# Fast HTML Parser [![NPM version](https://badge.fury.io/js/node-html-parser.png)](http://badge.fury.io/js/node-html-parser) [![Build Status](https://travis-ci.org/taoqf/node-html-parser.svg?branch=master)](https://travis-ci.org/taoqf/node-html-parser) Fast HTML Parser is a _very fast_ HTML parser. Which will generate a simplified DOM tree, with basic element query support. Per the design, it intends to parse massive HTML files in lowest price, thus the performance is the top priority. For this reason, some malformatted HTML may not be able to parse correctly, but most usual errors are covered (eg. HTML4 style no closing `
  • `, `` etc). ## Install ```shell npm install --save node-html-parser ``` ## Performance Faster than htmlparser2! ```shell node-html-parser:1.94548 ms/file ± 2.15709 libxmljs :5.28893 ms/file ± 3.69863 htmlparser :24.9625 ms/file ± 168.380 htmlparser2 :3.34011 ms/file ± 4.76959 parse5 :13.9589 ms/file ± 9.84068 high5 :6.98078 ms/file ± 4.47575 ``` Tested with [htmlparser-benchmark](https://github.com/AndreasMadsen/htmlparser-benchmark). ## Usage ```ts import { parse } from 'node-html-parser'; const root = parse(''); console.log(root.firstChild.structure); // ul#list // li // #text console.log(root.querySelector('#list')); // { tagName: 'ul', // rawAttrs: 'id="list"', // childNodes: // [ { tagName: 'li', // rawAttrs: '', // childNodes: [Object], // classNames: [] } ], // id: 'list', // classNames: [] } console.log(root.toString()); // root.set_content('
  • Hello World
  • '); root.toString(); //
  • Hello World
  • ``` ```js var HTMLParser = require('node-html-parser'); var root = HTMLParser.parse(''); ``` ## HTMLElement Methods ### parse(data[, options]) Parse given data, and return root of the generated DOM. - **data**, data to parse - **options**, parse options ```js { lowerCaseTagName: false, // convert tag name to lower case (hurt performance heavily) script: false, // retrieve content in
