A simplistic DOM Manipulation JavaScript library heavily inspired by emmet.io.
This piece of code
var sting = 'div#id.class>p>span{Text}+a[href=#]^section*2'
emmet.render(sting).append();
</script>
...will produce.
<div id="id" class="class">
<p>
<span>Text</span>
<a href="#"></a>
</p>
<section></section>
<section></section>
</div>
