Python lxml packaging elements

I was wondering what is the easiest way to wrap an element with another element using lxml and Python, for example, if I have an html fragment:

<h1>The cool title</h1>
<p>Something Neat</p>
<table>
<tr>
<td>aaa</td>
<td>bbb</td>
</tr>
</table>
<p>The end of the snippet</p>

And I want to wrap a table element with a section element as follows:

<h1>The cool title</h1>
<p>Something Neat</p>
<section>
<table>
<tr>
<td>aaa</td>
<td>bbb</td>
</tr>
</table>
</section>
<p>The end of the snippet</p>

Another thing I would like to do is to clear the XML document in h1s with a specific attribute and then wrap all the elements until the next h1 tag in the element, for example:

<h1 class='neat'>Subject 1</h1>
<p>Here is a bunch of boring text</p>
<h2>Minor Heading</h2>
<p>Here is some more</p>
<h1 class='neat>Subject 2</h1>
<p>And Even More</p>

Converted to:

<section>
<h1 class='neat'>Subject 1</h1>
<p>Here is a bunch of boring text</p>
<h2>Minor Heading</h2>
<p>Here is some more</p>
</section>
<section>
<h1 class='neat>Subject 2</h1>
<p>And Even More</p>
</section>

Thanks for the help, Chris.
