PostHTML Attrs Parser\n[![npm version](https://badge.fury.io/js/posthtml-attrs-parser.svg)](http://badge.fury.io/js/posthtml-attrs-parser)\n[![Build Status](https://travis-ci.org/maltsev/posthtml-attrs-parser.svg?branch=master)](https://travis-ci.org/maltsev/posthtml-attrs-parser)\n\n[PostHTML](https://github.com/posthtml/posthtml) helper that gives a better API to work with tag's attrs.\n\n\n## Usage\n```js\nvar posthtml = require('posthtml'),\n parseAttrs = require('posthtml-attrs-parser');\n\nposthtml()\n .use(function (tree) {\n var div = tree[0],\n attrs = parseAttrs(div.attrs);\n\n attrs.style['font-size'] = '15px';\n attrs.class.push('title-sub');\n\n\t\t// Compose attrs back to PostHTML-compatible format\n div.attrs = attrs.compose();\n })\n .process('
Hello!
')\n .then(function (result) {\n console.log(result.html);\n });\n\n//
Hello!
\n```\n\n\n## Attributes\nOnly `style` and `class` attributes are parsed by default (as object and array, respectively).\nFor other attributes the parsing rules should be specified (see \"Custom parsing rule\" below).\n\n\n### Default attributes\n#### `style`\n```js\n//
\nvar attrs = parseAttrs(div.attrs);\nconsole.log(attrs.style);\n/*\n{\n // If there is several properties with the same name,\n // then the values are packed in array\n 'color': ['red', 'blue'],\n 'font-size': '14px'\n}\n*/\n```\n\n\n#### `class`\n```js\n//
\nvar attrs = parseAttrs(div.attrs);\nconsole.log(attrs.class);\n// ['title', 'title-sub']\n```\n\n\n### Custom parsing rule\nYou can also define the parsing rule for other attributes.\n\n#### Array-like attribute\n```js\n//
\nvar attrs = parseAttrs(div.attrs, {\n rules: {\n\t\t'data-ids': {\n\t\t\tdelimiter: /\\s+/,\n // Optional parameter for stringifying attribute's values\n // If not set, glue = delimiter\n\t\t\tglue: ' '\n\t\t}\n\t}\n});\nconsole.log(attrs['data-ids']);\n// ['1', '2', '4', '5', '6']\n\nconsole.log(attrs.compose()['data-ids']);\n// 1 2 3 4 5 6\n```\n\n\n#### Object-like attribute\n```js\n//
\nvar attrs = parseAttrs(div.attrs, {\n\trules: {\n\t\t'data-config': {\n // Delimiter for key-value pairs\n\t\t\tdelimiter: ';',\n // Delimiter for a key-value\n\t\t\tkeyDelimiter: '=',\n\n // Optional parameter for stringifying key-value pairs\n // If not set, keyGlue = keyDelimiter\n\t\t\tglue: '; ',\n // Optional parameter for stringifying a key-value\n // If not set, glue = delimiter\n keyGlue: ' = '\n\t\t}\n\t}\n});\nconsole.log(attrs['data-config']);\n// {TEST: '1', ENV: 'debug', PATH: '.'}\n\nconsole.log(attrs.compose()['data-config']);\n// TEST = 1; ENV = debug; PATH = .\n```\n","_attachments":{},"homepage":"https://github.com/maltsev/posthtml-attrs-parser","bugs":{"url":"https://github.com/maltsev/posthtml-attrs-parser/issues"},"license":"MIT"}
