As an aside, since my goal is to re-write the urls in place, I don't see how HTML::LinkExtor would help. I can get the links just fine, I'm just having problems doing the re-writing inline. Am I missing something there?

Well, not really I guess. You could try going through line-by-line with a regex, that extracts the links, and then mangles them appropriately in-line. The LinkExtor approach would be to use it to grab all the links, then for each of those links, do an s///g on the text you have (lumped together as a single string) to do the URL mangling. This way *might be* slower (or impractical for other reasons), but given a choice between speed and correctness, my impulse usually lies with correctness. YMMV, of course!
