Select first two elements

It's been a while since I have done any XSL (maybe 2 1/2 years!) I have a 
friend that wants his last 2 posts from an atom xml feed to show. I'm *trying* 
to get any for loop that I can find in xsl to work, but nothing is at all.

Basic structure is like so:
<feed>
     <entry>
           <title></title>
           <content></content>
     </entry>
     ...
     ...
</feed>

I just need to be able to select the first two in the xml doc. Once I can get 
this, you won't hear a peep from me in another two years!

example:
