\nFrom the list of the same tag's attributes, the attribute which goes the first will be taken for comparison, others will be ignored (default: `false`).\n\n**Example**: `true`
\nFor example, the following two code samples will be considered to be equivalent:\n\n```html\nText\n```\n\n```html\nText\n```\n\n#### Presets\n\n* [bem](https://github.com/bem/html-differ/blob/master/presets/bem.json) - sets predefined options for [BEM](http://bem.info/).\n\n\n##### Usage\n\nPassing of a preset via the constructor:\n\n```js\nvar HtmlDiffer = require('html-differ').HtmlDiffer,\n htmlDiffer = new HtmlDiffer('bem');\n```\n\nRedefinition of a preset via the constructor:\n\n```js\nvar HtmlDiffer = require('html-differ').HtmlDiffer,\n htmlDiffer = new HtmlDiffer({ preset: 'bem', ignoreAttributes: [] });\n```\n\n#### Methods\n\n##### htmlDiffer.diffHtml\n\n**@param** *{String}* - the 1-st HTML code
\n**@param** *{String}* - the 2-nd HTML code
\n**@returns** *{Array of objects}* - [array with diffs](https://github.com/kpdecker/jsdiff#change-objects) between HTML\n\n##### htmlDiffer.isEqual\n\n**@param** *{String}* - the 1-st HTML code
\n**@param** *{String}* - the 2-nd HTML code
\n**@returns** *{Boolean}*\n\n\n### Logger\n\n```js\nvar logger = require('html-differ/lib/logger');\n```\n\n#### Methods\n\n##### logger.getDiffText\n\n**@param** *{Array of objects}* - the result of the work of the method [htmlDiffer.diffHtml](https://github.com/bem/html-differ/tree/master#htmldifferdiffhtml)
\n**@param** *{Object}* - options:
\n\n* **charsAroundDiff: Number** - the number of characters around the diff result between two HTML (default: `40`).\n\n**@returns** *{String}*\n\n##### logger.logDiffText\n**@param** *{Array of objects}* - the result of the work of the method [htmlDiffer.diffHtml](https://github.com/bem/html-differ/tree/master#htmldifferdiffhtml)
\n**@param** *{Object}* - options:
\n\n* **charsAroundDiff: Number** - the number of characters around the diff result between two HTML (default: `40`).\n\n**@returns** - pretty logging of diffs:\n\n
\n\n\n### Example\n\n```js\nvar fs = require('fs'),\n HtmlDiffer = require('html-differ').HtmlDiffer,\n logger = require('html-differ/lib/logger');\n\nvar html1 = fs.readFileSync('1.html', 'utf-8'),\n html2 = fs.readFileSync('2.html', 'utf-8');\n\nvar options = {\n ignoreAttributes: [],\n compareAttributesAsJSON: [],\n ignoreWhitespaces: true,\n ignoreComments: true,\n ignoreEndTags: false,\n ignoreDuplicateAttributes: false\n };\n\nvar htmlDiffer = new HtmlDiffer(options);\n\nvar diff = htmlDiffer.diffHtml(html1, html2),\n isEqual = htmlDiffer.isEqual(html1, html2),\n res = logger.getDiffText(diff, { charsAroundDiff: 40 });\n\nlogger.logDiffText(diff, { charsAroundDiff: 40 });\n```\n\n## Usage as a program\n\n```bash\n$ html-differ --help\nCompares two HTML\n\nUsage:\n html-differ [OPTIONS] [ARGS]\n\nOptions:\n -h, --help : Help\n -v, --version : Shows the version number\n --config=CONFIG : Path to a configuration JSON file\n --bem : Uses predefined options for BEM (deprecated)\n -p PRESET, --preset=PRESET : Name of a preset\n --chars-around-diff=CHARSAROUNDDIFF : The number of characters around the diff (default: 40)\n\nArguments:\n PATH1 : Path to the 1-st HTML file (required)\n PATH2 : Path to the 2-nd HTML file (required)\n```\n\n### Example\n\n```bash\n$ html-differ path/to/html1 path/to/html2\n\n$ html-differ --config=path/to/config --chars-around-diff=40 path/to/html1 path/to/html2\n\n$ html-differ --preset=bem path/to/html1 path/to/html2\n```\n\n### Configuration file\n\nStudy the following file `config.json`:\n\n```js\n{\n \"ignoreAttributes\": [],\n \"compareAttributesAsJSON\": [],\n \"ignoreWhitespaces\": true,\n \"ignoreComments\": true,\n \"ignoreEndTags\": false,\n \"ignoreDuplicateAttributes\": false\n}\n```\n\n## Masks\n\n**html-differ** supports handling of _masks_ in HTML.\n\nFor example, the following two code samples will be considered to be equivalent:\n\n```html\n\n```\n\n```html\n
\n```\n\n### Syntax\n\n_Masks_ in **html-differ** have the following syntax:\n\n```js\n{{RegExp}}\n```\n\nwhere:\n\n* `{{` – opening identifier of the _mask_.\n\n* `RegExp` – regular expression for matching with the corresponding value in another HTML. The syntax is similar to regular expressions in JavaScript written in a literal notation.\n\n* `}}` – closing identifier of the _mask_.\n\n### Screening\n\nThe rules of screening of symbols are similar to the rules which are used in regular expressions in JavaScript written in a literal notation.\n\nFor example, the following two code samples will be considered to be equivalent:\n\n```html\n
\n```\n\n```html\n
\n```\n\nIf you want to use `{{` or `}}` inside a mask, you should screen both curly braces, i.e. `\\{\\}` or `\\}\\}`.\n\nFor example, the following two code samples will be considered to be equivalent:\n\n```html\n
\n```\n\n```html\n
