HTML snippet:
<h1>Heading</h1>
<p>paragraph paragraph paragraph</p>
<h2>Heading</h2>
<p>paragraph paragraph paragraph</p>
The snippet above is equal to:
<section>
<h1>Heading</h1>
<p>paragraph paragraph paragraph</p>
<section>
<h2>Heading</h2>
<p>paragraph paragraph paragraph</p>
</section>
</section>
As mentioned here.
Now I want to do this by jQuery from the first snippet. Is there already an API for this?
Demo : http://jsfiddle.net/abdennour/LX2YX/
$('h2').next('p').andSelf().wrapAll('<section />');
$('h1').next().andSelf().next().andSelf().wrapAll('<section />');
You can see browser inspector to check your DOM tree :
