I think the easiest thing to do is use something like Sarissa to get your  
DOM Document. Find the elements you want with XPath. Then use something  
like Mozilla/Sarissa's serialize to convert the element to a text string.  
Then stick the HTML where you need with innerHTML and eval the JS.

Of course this is pretty simple JS (even if browser specific) and you  
don't need a special library for it (XHR and serialize, that is, the rest  
is cross browser). Plus you don't have to send the other stuff that the  
client doesn't need or won't be using.

best,
-Rob
