Look at your code: you've only instantiated an instance of an HTML::LinkExtor
object (and given it a sub to use). That's great, but you never told it to
actually *do* anything, which is why you aren't seeing anything.
Do a 'perldoc HTML::LinkExtor' from a cmd shell. You'll see that you'll need
to call a parse method to have it actually process your text. The syntax is
in the docs, so have fun. :-)
