Subject: Efficient way to do a simple Perl thing with Ruby

I have some Perl code that does something like this:

$copy =~ s{<!--#include\s+virtual\s*=\s*"([^"]*)"\s*-->}{get($1)}gem

Basically, apply a regex to a string, and for every match, call get($1) and 
replace the match with the return value of the get().  get() comes from 
LWP::Simple, and simply fetches the content at the given URL.

My Ruby-fu is failing me at coming up with a relatively concise yet readable 
way to do this in Ruby.  My implementation is, I am sure, much longer than 
necessary.

So, anyone have any ideas?  How would you do this?
