sorting lines by term inside a tag

I need to sort lines like this:

<li><a href="http://foo.com/">Lisa</li>
<li><a href="http://ymmv.com/">Bart</li>
<li><a href="http://donuts.com/">Homer</li>

by the name "inside" the a tag, thus:

<li><a href="http://ymmv.com/">Bart</li>
<li><a href="http://donuts.com/">Homer</li>
<li><a href="http://foo.com/">Lisa</li>

Can I do this within Vim?
