-
-  The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/commander-rb/commander).  
-  [API documentation](http://tj.github.com/commander.js/)
-
-
-## Installation
-
-    $ npm install commander
-
-## Option parsing
-
-Options with commander are defined with the `.option()` method, also serving as documentation for the options. The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.
-
-```js
-#!/usr/bin/env node
-
-/**
- * Module dependencies.
- */
-
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .option('-p, --peppers', 'Add peppers')
-  .option('-P, --pineapple', 'Add pineapple')
-  .option('-b, --bbq-sauce', 'Add bbq sauce')
-  .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')
-  .parse(process.argv);
-
-console.log('you ordered a pizza with:');
-if (program.peppers) console.log('  - peppers');
-if (program.pineapple) console.log('  - pineapple');
-if (program.bbqSauce) console.log('  - bbq');
-console.log('  - %s cheese', program.cheese);
-```
-
-Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc.
-
-Note that multi-word options starting with `--no` prefix negate the boolean value of the following word. For example, `--no-sauce` sets the value of `program.sauce` to false.
-
-```js
-#!/usr/bin/env node
-
-/**
- * Module dependencies.
- */
-
-var program = require('commander');
-
-program
-  .option('--no-sauce', 'Remove sauce')
-  .parse(process.argv);
-
-console.log('you ordered a pizza');
-if (program.sauce) console.log('  with sauce');
-else console.log(' without sauce');
-```
-
-To get string arguments from options you will need to use angle brackets <> for required inputs or square brackets [] for optional inputs. 
-
-e.g. ```.option('-m --myarg [myVar]', 'my super cool description')```
-
-Then to access the input if it was passed in.
-
-e.g. ```var myInput = program.myarg```
-
-**NOTE**: If you pass a argument without using brackets the example above will return true and not the value passed in.
-
-
-## Version option
-
-Calling the `version` implicitly adds the `-V` and `--version` options to the command.
-When either of these options is present, the command prints the version number and exits.
-
-    $ ./examples/pizza -V
-    0.0.1
-
-If you want your program to respond to the `-v` option instead of the `-V` option, simply pass custom flags to the `version` method using the same syntax as the `option` method.
-
-```js
-program
-  .version('0.0.1', '-v, --version')
-```
-
-The version flags can be named anything, but the long option is required.
-
-## Command-specific options
-
-You can attach options to a command.
-
-```js
-#!/usr/bin/env node
-
-var program = require('commander');
-
-program
-  .command('rm <dir>')
-  .option('-r, --recursive', 'Remove recursively')
-  .action(function (dir, cmd) {
-    console.log('remove ' + dir + (cmd.recursive ? ' recursively' : ''))
-  })
-
-program.parse(process.argv)
-```
-
-A command's options are validated when the command is used. Any unknown options will be reported as an error. However, if an action-based command does not define an action, then the options are not validated.
-
-## Coercion
-
-```js
-function range(val) {
-  return val.split('..').map(Number);
-}
-
-function list(val) {
-  return val.split(',');
-}
-
-function collect(val, memo) {
-  memo.push(val);
-  return memo;
-}
-
-function increaseVerbosity(v, total) {
-  return total + 1;
-}
-
-program
-  .version('0.1.0')
-  .usage('[options] <file ...>')
-  .option('-i, --integer <n>', 'An integer argument', parseInt)
-  .option('-f, --float <n>', 'A float argument', parseFloat)
-  .option('-r, --range <a>..<b>', 'A range', range)
-  .option('-l, --list <items>', 'A list', list)
-  .option('-o, --optional [value]', 'An optional value')
-  .option('-c, --collect [value]', 'A repeatable value', collect, [])
-  .option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0)
-  .parse(process.argv);
-
-console.log(' int: %j', program.integer);
-console.log(' float: %j', program.float);
-console.log(' optional: %j', program.optional);
-program.range = program.range || [];
-console.log(' range: %j..%j', program.range[0], program.range[1]);
-console.log(' list: %j', program.list);
-console.log(' collect: %j', program.collect);
-console.log(' verbosity: %j', program.verbose);
-console.log(' args: %j', program.args);
-```
-
-## Regular Expression
-```js
-program
-  .version('0.1.0')
-  .option('-s --size <size>', 'Pizza size', /^(large|medium|small)$/i, 'medium')
-  .option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i)
-  .parse(process.argv);
-
-console.log(' size: %j', program.size);
-console.log(' drink: %j', program.drink);
-```
-
-## Variadic arguments
-
- The last argument of a command can be variadic, and only the last argument.  To make an argument variadic you have to
- append `...` to the argument name.  Here is an example:
-
-```js
-#!/usr/bin/env node
-
-/**
- * Module dependencies.
- */
-
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .command('rmdir <dir> [otherDirs...]')
-  .action(function (dir, otherDirs) {
-    console.log('rmdir %s', dir);
-    if (otherDirs) {
-      otherDirs.forEach(function (oDir) {
-        console.log('rmdir %s', oDir);
-      });
-    }
-  });
-
-program.parse(process.argv);
-```
-
- An `Array` is used for the value of a variadic argument.  This applies to `program.args` as well as the argument passed
- to your action as demonstrated above.
-
-## Specify the argument syntax
-
-```js
-#!/usr/bin/env node
-
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .arguments('<cmd> [env]')
-  .action(function (cmd, env) {
-     cmdValue = cmd;
-     envValue = env;
-  });
-
-program.parse(process.argv);
-
-if (typeof cmdValue === 'undefined') {
-   console.error('no command given!');
-   process.exit(1);
-}
-console.log('command:', cmdValue);
-console.log('environment:', envValue || "no environment given");
-```
-Angled brackets (e.g. `<cmd>`) indicate required input. Square brackets (e.g. `[env]`) indicate optional input.
-
-## Git-style sub-commands
-
-```js
-// file: ./examples/pm
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .command('install [name]', 'install one or more packages')
-  .command('search [query]', 'search with optional query')
-  .command('list', 'list packages installed', {isDefault: true})
-  .parse(process.argv);
-```
-
-When `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools.  
-The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`.
-
-Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the subcommand from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified.
-
-If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
-
-### `--harmony`
-
-You can enable `--harmony` option in two ways:
-* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern.
-* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.
-
-## Automated --help
-
- The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:
-
-```  
-$ ./examples/pizza --help
-Usage: pizza [options]
-
-An application for pizzas ordering
-
-Options:
-  -h, --help           output usage information
-  -V, --version        output the version number
-  -p, --peppers        Add peppers
-  -P, --pineapple      Add pineapple
-  -b, --bbq            Add bbq sauce
-  -c, --cheese <type>  Add the specified type of cheese [marble]
-  -C, --no-cheese      You do not want any cheese
-```
-
-## Custom help
-
- You can display arbitrary `-h, --help` information
- by listening for "--help". Commander will automatically
- exit once you are done so that the remainder of your program
- does not execute causing undesired behaviors, for example
- in the following executable "stuff" will not output when
- `--help` is used.
-
-```js
-#!/usr/bin/env node
-
-/**
- * Module dependencies.
- */
-
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .option('-f, --foo', 'enable some foo')
-  .option('-b, --bar', 'enable some bar')
-  .option('-B, --baz', 'enable some baz');
-
-// must be before .parse() since
-// node's emit() is immediate
-
-program.on('--help', function(){
-  console.log('')
-  console.log('Examples:');
-  console.log('  $ custom-help --help');
-  console.log('  $ custom-help -h');
-});
-
-program.parse(process.argv);
-
-console.log('stuff');
-```
-
-Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run:
-
-```
-Usage: custom-help [options]
-
-Options:
-  -h, --help     output usage information
-  -V, --version  output the version number
-  -f, --foo      enable some foo
-  -b, --bar      enable some bar
-  -B, --baz      enable some baz
-
-Examples:
-  $ custom-help --help
-  $ custom-help -h
-```
-
-## .outputHelp(cb)
-
-Output help information without exiting.
-Optional callback cb allows post-processing of help text before it is displayed.
-
-If you want to display help by default (e.g. if no command was provided), you can use something like:
-
-```js
-var program = require('commander');
-var colors = require('colors');
-
-program
-  .version('0.1.0')
-  .command('getstream [url]', 'get stream URL')
-  .parse(process.argv);
-
-if (!process.argv.slice(2).length) {
-  program.outputHelp(make_red);
-}
-
-function make_red(txt) {
-  return colors.red(txt); //display the help text in red on the console
-}
-```
-
-## .help(cb)
-
-  Output help information and exit immediately.
-  Optional callback cb allows post-processing of help text before it is displayed.
-
-
-## Custom event listeners
- You can execute custom actions by listening to command and option events.
-
-```js
-program.on('option:verbose', function () {
-  process.env.VERBOSE = this.verbose;
-});
-
-// error on unknown commands
-program.on('command:*', function () {
-  console.error('Invalid command: %s\nSee --help for a list of available commands.', program.args.join(' '));
-  process.exit(1);
-});
-```
-
-## Examples
-
-```js
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .option('-C, --chdir <path>', 'change the working directory')
-  .option('-c, --config <path>', 'set config path. defaults to ./deploy.conf')
-  .option('-T, --no-tests', 'ignore test hook');
-
-program
-  .command('setup [env]')
-  .description('run setup commands for all envs')
-  .option("-s, --setup_mode [mode]", "Which setup mode to use")
-  .action(function(env, options){
-    var mode = options.setup_mode || "normal";
-    env = env || 'all';
-    console.log('setup for %s env(s) with %s mode', env, mode);
-  });
-
-program
-  .command('exec <cmd>')
-  .alias('ex')
-  .description('execute the given remote cmd')
-  .option("-e, --exec_mode <mode>", "Which exec mode to use")
-  .action(function(cmd, options){
-    console.log('exec "%s" using %s mode', cmd, options.exec_mode);
-  }).on('--help', function() {
-    console.log('');
-    console.log('Examples:');
-    console.log('');
-    console.log('  $ deploy exec sequential');
-    console.log('  $ deploy exec async');
-  });
-
-program
-  .command('*')
-  .action(function(env){
-    console.log('deploying "%s"', env);
-  });
-
-program.parse(process.argv);
-```

-# cssfilter
-Sanitize untrusted CSS with a configuration specified by a Whitelist. 根据白名单过滤CSS
-
-
-## 安装
-
-```bash
-$ npm install cssfilter --save
-```
-
-
-## 使用方法
-
-```javascript
-var cssfilter = require('cssfilter');
-var css = cssfilter('position:fixed; /* this is comments */ width:100px; height:100px; background:#aaa;');
-console.log(css);
-// 输出：width:100px; height:100px; background:#aaa;
-// 因为position不在白名单允许范围
-```
-
-或者：
-
-```javascript
-options = {
-  // 白名单，可选
-  whiteList: {
-    a: true,                 // true表示允许
-    b: /^fixed|relative$/,   // 正则test()返回true表示允许
-    c: function (value) {
-      // 返回true表示允许
-    },
-    d: false                 // 除以上三个以外，所有值均表示不允许
-  },
-  // 当匹配到一个在白名单中的属性时
-  onAttr: function (name, value, options) {
-    // name为属性名
-    // value为属性值
-    // 返回字符串表示覆盖此段CSS
-    // 不返回任何值表示使用默认生成方法，即 name:value
-  },
-  // 当匹配到一个不在白名单中的属性时
-  onIgnoreAttr: function (name, value, options) {
-    // name为属性名
-    // value为属性值
-    // 返回字符串表示覆盖此段CSS
-    // 不返回任何值表示使用默认生成方法，即将此段CSS去掉
-  }
-};
-mycss = new cssfilter.FilterCSS(options);
-// then apply mycss.process()
-css = mycss.process('position:fixed; width:100px; height:100px; background:#aaa;');
-console.log(css);

-* **cnpmjs.org** - Private npm registry and web for Enterprise - https://github.com/cnpm/cnpmjs.org
-
-## Install
-
-### NPM
-
-```bash
-npm install xss
-```
-
-### Bower
-
-```bash
-bower install xss
-```
-
-Or
-
-```bash
-bower install https://github.com/leizongmin/js-xss.git
-```
-
-## Usages
-
-### On Node.js
-
-```javascript
-var xss = require("xss");
-var html = xss('<script>alert("xss");</script>');
-console.log(html);
-```
-
-### On Browser
-
-Shim mode (reference file `test/test.html`):
-
-```html
-<script src="https://rawgit.com/leizongmin/js-xss/master/dist/xss.js"></script>
-<script>
-// apply function filterXSS in the same way
-var html = filterXSS('<script>alert("xss");</scr' + 'ipt>');
-alert(html);
-</script>
-```
-
-AMD mode - shim:
-
-```html
-<script>
-require.config({
-  baseUrl: './',
-  paths: {
-    xss: 'https://rawgit.com/leizongmin/js-xss/master/dist/xss.js'
-  },
-  shim: {
-    xss: {exports: 'filterXSS'}
-  }
-})
-require(['xss'], function (xss) {
-  var html = xss('<script>alert("xss");</scr' + 'ipt>');
-  alert(html);
-});
-</script>
-```
-
-**Notes: please don't use the URL https://rawgit.com/leizongmin/js-xss/master/dist/xss.js in production environment.**
-
-## Command Line Tool
-
-### Process File
-
-You can use the xss command line tool to process a file. Usage:
-
-```bash
-xss -i <input_file> -o <output_file>
-```
-
-Example:
-
-```bash
-xss -i origin.html -o target.html
-```
-
-### Active Test
-
-Run the following command, them you can type HTML
-code in the command-line, and check the filtered output:
-
-```bash
-xss -t
-```
-
-For more details, please run `$ xss -h` to see it.
-
-## Custom filter rules
-
-When using the `xss()` function, the second parameter could be used to specify
-custom rules:
-
-```javascript
-options = {}; // Custom rules
-html = xss('<script>alert("xss");</script>', options);
-```
-
-To avoid passing `options` every time, you can also do it in a faster way by
-creating a `FilterXSS` instance:
-
-```javascript
-options = {}; // Custom rules
-myxss = new xss.FilterXSS(options);
-// then apply myxss.process()
-html = myxss.process('<script>alert("xss");</script>');
-```
-
-Details of parameters in `options` would be described below.
-
-### Whitelist
-
-By specifying a `whiteList`, e.g. `{ 'tagName': [ 'attr-1', 'attr-2' ] }`. Tags
-and attributes not in the whitelist would be filter out. For example:
-
-```javascript
-// only tag a and its attributes href, title, target are allowed
-var options = {
-  whiteList: {
-    a: ["href", "title", "target"]
-  }
-};
-// With the configuration specified above, the following HTML:
-// <a href="#" onclick="hello()"><i>Hello</i></a>
-// would become:
-// <a href="#">Hello</a>
-```
-
-For the default whitelist, please refer `xss.whiteList`.
-
-### Customize the handler function for matched tags
-
-By specifying the handler function with `onTag`:
-
-```javascript
-function onTag(tag, html, options) {
-  // tag is the name of current tag, e.g. 'a' for tag <a>
-  // html is the HTML of this tag, e.g. '<a>' for tag <a>
-  // options is some addition informations:
-  //   isWhite    boolean, whether the tag is in whitelist
-  //   isClosing  boolean, whether the tag is a closing tag, e.g. true for </a>
-  //   position        integer, the position of the tag in output result
-  //   sourcePosition  integer, the position of the tag in input HTML source
-  // If a string is returned, the current tag would be replaced with the string
-  // If return nothing, the default measure would be taken:
-  //   If in whitelist: filter attributes using onTagAttr, as described below
-  //   If not in whitelist: handle by onIgnoreTag, as described below
-}
-```
-
-### Customize the handler function for attributes of matched tags
-
-By specifying the handler function with `onTagAttr`:
-
-```javascript
-function onTagAttr(tag, name, value, isWhiteAttr) {
-  // tag is the name of current tag, e.g. 'a' for tag <a>
-  // name is the name of current attribute, e.g. 'href' for href="#"
-  // isWhiteAttr whether the attribute is in whitelist
-  // If a string is returned, the attribute would be replaced with the string
-  // If return nothing, the default measure would be taken:
-  //   If in whitelist: filter the value using safeAttrValue as described below
-  //   If not in whitelist: handle by onIgnoreTagAttr, as described below
-}
-```
-
-### Customize the handler function for tags not in the whitelist
-
-By specifying the handler function with `onIgnoreTag`:
-
-```javascript
-function onIgnoreTag(tag, html, options) {
-  // Parameters are the same with onTag
-  // If a string is returned, the tag would be replaced with the string
-  // If return nothing, the default measure would be taken (specifies using
-  // escape, as described below)
-}
-```
-
-### Customize the handler function for attributes not in the whitelist
-
-By specifying the handler function with `onIgnoreTagAttr`:
-
-```javascript
-function onIgnoreTagAttr(tag, name, value, isWhiteAttr) {
-  // Parameters are the same with onTagAttr
-  // If a string is returned, the value would be replaced with this string
-  // If return nothing, then keep default (remove the attribute)
-}
-```
-
-### Customize escaping function for HTML
-
-By specifying the handler function with `escapeHtml`. Following is the default
-function **(Modification is not recommended)**:
-
-```javascript
-function escapeHtml(html) {
-  return html.replace(/</g, "&lt;").replace(/>/g, "&gt;");
-}
-```
-
-### Customize escaping function for value of attributes
-
-By specifying the handler function with `safeAttrValue`:
-
-```javascript
-function safeAttrValue(tag, name, value) {
-  // Parameters are the same with onTagAttr (without options)
-  // Return the value as a string
-}
-```
-
-### Customize CSS filter
-
-If you allow the attribute `style`, the value will be processed by [cssfilter](https://github.com/leizongmin/js-css-filter) module. The cssfilter module includes a default css whitelist. You can specify the options for cssfilter module like this:
-
-```javascript
-myxss = new xss.FilterXSS({
-  css: {
-    whiteList: {
-      position: /^fixed|relative$/,
-      top: true,
-      left: true
-    }
-  }
-});
-html = myxss.process('<script>alert("xss");</script>');
-```
-
-If you don't want to filter out the `style` content, just specify `false` to the `css` option:
-
-```javascript
-myxss = new xss.FilterXSS({
-  css: false
-});
-```
-
-For more help, please see https://github.com/leizongmin/js-css-filter
-
-### Quick Start
-
-#### Filter out tags not in the whitelist
-
-By using `stripIgnoreTag` parameter:
-
-* `true` filter out tags not in the whitelist
-* `false`: by default: escape the tag using configured `escape` function
-
-Example:
-
-If `stripIgnoreTag = true` is set, the following code:
-
-```html
-code:<script>alert(/xss/);</script>
-```
-
-would output filtered:
-
-```html
-code:alert(/xss/);
-```
-
-#### Filter out tags and tag bodies not in the whitelist
-
-By using `stripIgnoreTagBody` parameter:
-
-* `false|null|undefined` by default: do nothing
-* `'*'|true`: filter out all tags not in the whitelist
-* `['tag1', 'tag2']`: filter out only specified tags not in the whitelist
-
-Example:
-
-If `stripIgnoreTagBody = ['script']` is set, the following code:
-
-```html
-code:<script>alert(/xss/);</script>
-```
-
-would output filtered:
-
-```html
-code:
-```
-
-#### Filter out HTML comments
-
-By using `allowCommentTag` parameter:
-
-* `true`: do nothing
-* `false` by default: filter out HTML comments
-
-Example:
-
-If `allowCommentTag = false` is set, the following code:
-
-```html
-code:<!-- something --> END
-```
-
-would output filtered:
-
-```html
-code: END
-```
-
-## Examples
-
-### Allow attributes of whitelist tags start with `data-`
-
-```javascript
-var source = '<div a="1" b="2" data-a="3" data-b="4">hello</div>';
-var html = xss(source, {
-  onIgnoreTagAttr: function(tag, name, value, isWhiteAttr) {
-    if (name.substr(0, 5) === "data-") {
-      // escape its value using built-in escapeAttrValue function
-      return name + '="' + xss.escapeAttrValue(value) + '"';
-    }
-  }
-});
-
-console.log("%s\nconvert to:\n%s", source, html);
-```
-
-Result:
-
-```html
-<div a="1" b="2" data-a="3" data-b="4">hello</div>
-convert to:
-<div data-a="3" data-b="4">hello</div>
-```
-
-### Allow tags start with `x-`
-
-```javascript
-var source = "<x><x-1>he<x-2 checked></x-2>wwww</x-1><a>";
-var html = xss(source, {
-  onIgnoreTag: function(tag, html, options) {
-    if (tag.substr(0, 2) === "x-") {
-      // do not filter its attributes
-      return html;
-    }
-  }
-});
-
-console.log("%s\nconvert to:\n%s", source, html);
-```
-
-Result:
-
-```html
-<x><x-1>he<x-2 checked></x-2>wwww</x-1><a>
-convert to:
-&lt;x&gt;<x-1>he<x-2 checked></x-2>wwww</x-1><a>
-```
-
-### Parse images in HTML
-
-```javascript
-var source =
-  '<img src="img1">a<img src="img2">b<img src="img3">c<img src="img4">d';
-var list = [];
-var html = xss(source, {
-  onTagAttr: function(tag, name, value, isWhiteAttr) {
-    if (tag === "img" && name === "src") {
-      // Use the built-in friendlyAttrValue function to escape attribute
-      // values. It supports converting entity tags such as &lt; to printable
-      // characters such as <
-      list.push(xss.friendlyAttrValue(value));
-    }
-    // Return nothing, means keep the default handling measure
-  }
-});
-
-console.log("image list:\n%s", list.join(", "));
-```
-
-Result:
-
-```html
-image list:
-img1, img2, img3, img4
-```
-
-### Filter out HTML tags (keeps only plain text)
-
-```javascript
-var source = "<strong>hello</strong><script>alert(/xss/);</script>end";
-var html = xss(source, {
-  whiteList: [], // empty, means filter out all tags
-  stripIgnoreTag: true, // filter out all HTML not in the whilelist
-  stripIgnoreTagBody: ["script"] // the script tag is a special case, we need
-  // to filter out its content
-});
-
-console.log("text: %s", html);
-```
-
-Result:
-
-```html
-text: helloend
-```

-// 使用函数名 filterXSS，用法一样
-var html = filterXSS('<script>alert("xss");</scr' + 'ipt>');
-alert(html);

-```
-
-AMD 模式（参考文件 `test/test_amd.html`）:

-require.config({
-  baseUrl: './',
-  paths: {
-    xss: 'https://rawgit.com/leizongmin/js-xss/master/dist/xss.js'
-  },
-  shim: {
-    xss: {exports: 'filterXSS'}
-  }
-})
-require(['xss'], function (xss) {
-  var html = xss('<script>alert("xss");</scr' + 'ipt>');
-  alert(html);
-});
-</script>
-```

-
-### 使用命令行工具来对文件进行 XSS 处理
-
-### 处理文件
-
-可通过内置的 `xss` 命令来对输入的文件进行 XSS 处理。使用方法：
-
-```bash
-xss -i <源文件> -o <目标文件>
-```
-
-例：
-
-```bash
-xss -i origin.html -o target.html
-```
-
-### 在线测试
-
-执行以下命令，可在命令行中输入 HTML 代码，并看到过滤后的代码：
-
-```bash
-xss -t
-```
-
-详细命令行参数说明，请输入 `$ xss -h` 来查看。
-
-## 自定义过滤规则
-
-在调用 `xss()` 函数进行过滤时，可通过第二个参数来设置自定义规则：
-
-```javascript
-options = {}; // 自定义规则
-html = xss('<script>alert("xss");</script>', options);
-```
-
-如果不想每次都传入一个 `options` 参数，可以创建一个 `FilterXSS` 实例（使用这种方法速度更快）：
-
-```
-options = {};  // 自定义规则
-myxss = new xss.FilterXSS(options);
-// 以后直接调用 myxss.process() 来处理即可
-html = myxss.process('<script>alert("xss");</script>');
-```
-
-`options` 参数的详细说明见下文。
-
-### 白名单
-
-通过 `whiteList` 来指定，格式为：`{'标签名': ['属性1', '属性2']}`。不在白名单上的标签将被过滤，不在白名单上的属性也会被过滤。以下是示例：
-
-```javascript
-// 只允许a标签，该标签只允许href, title, target这三个属性
-var options = {
-  whiteList: {
-    a: ["href", "title", "target"]
-  }
-};
-// 使用以上配置后，下面的HTML
-// <a href="#" onclick="hello()"><i>大家好</i></a>
-// 将被过滤为
-// <a href="#">大家好</a>
-```
-
-默认白名单参考 `xss.whiteList`。
-
-### 自定义匹配到标签时的处理方法
-
-通过 `onTag` 来指定相应的处理函数。以下是详细说明：
-
-```javascript
-function onTag(tag, html, options) {
-  // tag是当前的标签名称，比如<a>标签，则tag的值是'a'
-  // html是该标签的HTML，比如<a>标签，则html的值是'<a>'
-  // options是一些附加的信息，具体如下：
-  //   isWhite    boolean类型，表示该标签是否在白名单上
-  //   isClosing  boolean类型，表示该标签是否为闭合标签，比如</a>时为true
-  //   position        integer类型，表示当前标签在输出的结果中的起始位置
-  //   sourcePosition  integer类型，表示当前标签在原HTML中的起始位置
-  // 如果返回一个字符串，则当前标签将被替换为该字符串
-  // 如果不返回任何值，则使用默认的处理方法：
-  //   在白名单上：  通过onTagAttr来过滤属性，详见下文
-  //   不在白名单上：通过onIgnoreTag指定，详见下文
-}
-```
-
-### 自定义匹配到标签的属性时的处理方法
-
-通过 `onTagAttr` 来指定相应的处理函数。以下是详细说明：
-
-```javascript
-function onTagAttr(tag, name, value, isWhiteAttr) {
-  // tag是当前的标签名称，比如<a>标签，则tag的值是'a'
-  // name是当前属性的名称，比如href="#"，则name的值是'href'
-  // value是当前属性的值，比如href="#"，则value的值是'#'
-  // isWhiteAttr是否为白名单上的属性
-  // 如果返回一个字符串，则当前属性值将被替换为该字符串
-  // 如果不返回任何值，则使用默认的处理方法
-  //   在白名单上：  调用safeAttrValue来过滤属性值，并输出该属性，详见下文
-  //   不在白名单上：通过onIgnoreTagAttr指定，详见下文
-}
-```
-
-### 自定义匹配到不在白名单上的标签时的处理方法
-
-通过 `onIgnoreTag` 来指定相应的处理函数。以下是详细说明：
-
-```javascript
-function onIgnoreTag(tag, html, options) {
-  // 参数说明与onTag相同
-  // 如果返回一个字符串，则当前标签将被替换为该字符串
-  // 如果不返回任何值，则使用默认的处理方法（通过escape指定，详见下文）
-}
-```
-
-### 自定义匹配到不在白名单上的属性时的处理方法
-
-通过 `onIgnoreTagAttr` 来指定相应的处理函数。以下是详细说明：
-
-```javascript
-function onIgnoreTagAttr(tag, name, value, isWhiteAttr) {
-  // 参数说明与onTagAttr相同
-  // 如果返回一个字符串，则当前属性值将被替换为该字符串
-  // 如果不返回任何值，则使用默认的处理方法（删除该属）
-}
-```
-
-### 自定义 HTML 转义函数
-
-通过 `escapeHtml` 来指定相应的处理函数。以下是默认代码 **（不建议修改）** ：
-
-```javascript
-function escapeHtml(html) {
-  return html.replace(/</g, "&lt;").replace(/>/g, "&gt;");
-}
-```
-
-### 自定义标签属性值的转义函数
-
-通过 `safeAttrValue` 来指定相应的处理函数。以下是详细说明：
-
-```javascript
-function safeAttrValue(tag, name, value) {
-  // 参数说明与onTagAttr相同（没有options参数）
-  // 返回一个字符串表示该属性值
-}
-```
-
-### 自定义 CSS 过滤器
-
-如果配置中允许了标签的 `style` 属性，则它的值会通过[cssfilter](https://github.com/leizongmin/js-css-filter) 模块处理。
-`cssfilter` 模块包含了一个默认的 CSS 白名单，你可以通过以下的方式配置：
-
-```javascript
-myxss = new xss.FilterXSS({
-  css: {
-    whiteList: {
-      position: /^fixed|relative$/,
-      top: true,
-      left: true
-    }
-  }
-});
-html = myxss.process('<script>alert("xss");</script>');
-```
-
-如果不想使用 CSS 过滤器来处理 `style` 属性的内容，可指定 `css` 选项的值为 `false`：
-
-```javascript
-myxss = new xss.FilterXSS({
-  css: false
-});
-```
-
-要获取更多的帮助信息可看这里：https://github.com/leizongmin/js-css-filter
-
-### 快捷配置
-
-#### 去掉不在白名单上的标签
-
-通过 `stripIgnoreTag` 来设置：
-
-* `true`：去掉不在白名单上的标签
-* `false`：（默认），使用配置的`escape`函数对该标签进行转义
-
-示例：
-
-当设置 `stripIgnoreTag = true`时，以下代码
-
-```html
-code:<script>alert(/xss/);</script>
-```
-
-过滤后将输出
-
-```html
-code:alert(/xss/);
-```
-
-#### 去掉不在白名单上的标签及标签体
-
-通过 `stripIgnoreTagBody` 来设置：
-
-* `false|null|undefined`：（默认），不特殊处理
-* `'*'|true`：去掉所有不在白名单上的标签
-* `['tag1', 'tag2']`：仅去掉指定的不在白名单上的标签
-
-示例：
-
-当设置 `stripIgnoreTagBody = ['script']`时，以下代码
-
-```html
-code:<script>alert(/xss/);</script>
-```
-
-过滤后将输出
-
-```html
-code:
-```
-
-#### 去掉 HTML 备注
-
-通过 `allowCommentTag` 来设置：
-
-* `true`：不处理
-* `false`：（默认），自动去掉 HTML 中的备注
-
-示例：
-
-当设置 `allowCommentTag = false` 时，以下代码
-
-```html
-code:<!-- something --> END
-```
-
-过滤后将输出
-
-```html
-code: END
-```
-
-## 应用实例
-
-### 允许标签以 data-开头的属性
-
-```javascript
-var source = '<div a="1" b="2" data-a="3" data-b="4">hello</div>';
-var html = xss(source, {
-  onIgnoreTagAttr: function(tag, name, value, isWhiteAttr) {
-    if (name.substr(0, 5) === "data-") {
-      // 通过内置的escapeAttrValue函数来对属性值进行转义
-      return name + '="' + xss.escapeAttrValue(value) + '"';
-    }
-  }
-});
-
-console.log("%s\nconvert to:\n%s", source, html);
-```
-
-运行结果：
-
-```html
-<div a="1" b="2" data-a="3" data-b="4">hello</div>
-convert to:
-<div data-a="3" data-b="4">hello</div>
-```
-
-### 允许名称以 x-开头的标签
-
-```javascript
-var source = "<x><x-1>he<x-2 checked></x-2>wwww</x-1><a>";
-var html = xss(source, {
-  onIgnoreTag: function(tag, html, options) {
-    if (tag.substr(0, 2) === "x-") {
-      // 不对其属性列表进行过滤
-      return html;
-    }
-  }
-});
-
-console.log("%s\nconvert to:\n%s", source, html);
-```
-
-运行结果：
-
-```html
-<x><x-1>he<x-2 checked></x-2>wwww</x-1><a>
-convert to:
-&lt;x&gt;<x-1>he<x-2 checked></x-2>wwww</x-1><a>
-```
-
-### 分析 HTML 代码中的图片列表
-
-```javascript
-var source =
-  '<img src="img1">a<img src="img2">b<img src="img3">c<img src="img4">d';
-var list = [];
-var html = xss(source, {
-  onTagAttr: function(tag, name, value, isWhiteAttr) {
-    if (tag === "img" && name === "src") {
-      // 使用内置的friendlyAttrValue函数来对属性值进行转义，可将&lt;这类的实体标记转换成打印字符<
-      list.push(xss.friendlyAttrValue(value));
-    }
-    // 不返回任何值，表示还是按照默认的方法处理
-  }
-});
-
-console.log("image list:\n%s", list.join(", "));
-```
-
-运行结果：
-
-```html
-image list:
-img1, img2, img3, img4
-```
-
-### 去除 HTML 标签（只保留文本内容）
-
-```javascript
-var source = "<strong>hello</strong><script>alert(/xss/);</script>end";
-var html = xss(source, {
-  whiteList: [], // 白名单为空，表示过滤所有标签
-  stripIgnoreTag: true, // 过滤所有非白名单标签的HTML
-  stripIgnoreTagBody: ["script"] // script标签较特殊，需要过滤标签中间的内容
-});
-
-console.log("text: %s", html);
-```
-
-运行结果：
-
-```html
-text: helloend
-```
