You may be on the wrong track. When you say "in HTML source code", it
is important to understand that a legitimate browser "link" is always
going to be delimited by quotes, ie: href="
http://...";, src="
http://...";.
It is far more dificult when you need to grab URLs that are not a part
of HTML syntax, as when they occur in an unlinked form in the HTML's body
text, or when they occur anywhere else, as in email, Word documents,
Stickies files, etc.
Here are the two primary documents that defined the URL:
<
http://RFC.net/rfc1738.html>
<
http://RFC.net/rfc1808.html>
If you are making use of regular expressions, there are lots of perl
examples out there of how to extract a legitamte URL out of any kind
of text, but I don't seem able to find any links at the moment.

Which will work 99% of the time. Be aware that sometimes people will
type a URL in a "word-processy" sort of way that can trip you up, as when
normal sentence punctuation and whitespace are added.
I'll try to post a URL extractor of my own sometime later today...
