var html2json = require('html2json_2').html2json;
var json2html = require('html2json_2').json2html;

API

json === html2json(document.body.innerHTML);
html === json2html(json);

console.assert(json === html);

json === html2json(document.body.innerHTML, {removeNonRenderingSpaces: true});

JSON format

Sample

html:

<div id="1" class="foo" style="margin: 0">
<h2>sample text with <code>inline tag</code></h2>
<pre id="demo" class="foo bar">foo</pre>
<pre id="output" class="goo">goo</pre>
<input id="execute" type="button" value="execute"/>
</div>

json:

{
  node: 'root',
  child: [
    {
      node: 'element',
      tag: 'div',
      attr: { id: '1', class: 'foo' },
      style: {margin: '0'},  
      child: [
        {
          node: 'element',
          tag: 'h2',
          child: [
            { node: 'text', text: 'sample text with ' },
            { node: 'element', tag: 'code', child: [{ node: 'text', text: 'inline tag' }] }
          ]
        },
        {
          node: 'element',
          tag: 'pre',
          attr: { id: 'demo', class: ['foo', 'bar'] },
          child: [{ node: 'text', text: 'foo' }]
        },
        {
          node: 'element',
          tag: 'pre',
          attr: { id: 'output', class: 'goo' },
          child: [{ node: 'text', text: 'goo' }]
        },
        {
          node: 'element',
          tag: 'input',
          attr: { id: 'execute', type: 'button', value: 'execute' }
        }
      ]
    }
  ]
}

<head>
    <meta charset="UTF-8">
    <title>Space Tests</title>
</head>
<body>
    <div>
        <p>
