Neutron HTML5 Parser #

Here is a small pure-JavaScript HTML5 parser that can run on browsers as well as NodeJS with jsdom.

_Credit goes to John Resig for his code written back in 2008 and Erik Arvidsson for his code written piror to that._
This code has been updated to work with HTML 5 to fix several problems.

Use case

For parsing templates on both client and server side.
This library may soon be used internally in htmlizer.

For only server-side use case, you may like to use htmlparser2 or high5. Note: DOCTYPE gets ignored by htmlparser2.

For only client-side use case, you can look into jQuery.parseHTML() or native DOMParser (IE10+).

Usage

Add htmlparser.js to head tag or require with nodejs.

$3

//Returns DocumentFragment.
var documentfragment = HTMLtoDOM("

Hello World");

//If doctype is given then returns HTMLDocument
var doc = HTMLtoDOM("test");

//on NodeJS
var factory = require('neutron-html5parser'),
jsdom = require('jsdom'),
HTMLtoDOM = factory(jsdom.jsdom('').parentWindow);

While this library doesn’t cover the full gamut of possible weirdness that HTML provides, it does handle a lot of the most obvious stuff. All of the following are accounted for:
