What I'm trying to do is to parse URLs of different sorts, ftp, http,

You might want to consider using vbCode, there is a nice class for PHP
here:

HTH, cheers.

Thanks, but I already use PEAR HTML_BBCodeParser for that part.. :)
I solved it by a lookbehind, if there isn't a whitespace before the URL,
I answered your question stating that a regexp with a
negative-lookahead assertion would probably be a good way to go...
but it seems my post never arrived ... anyway I think a negative lookahead or
lookbehind assertion will cut it. I would just like to add that you might consider
looking behind for something a little more specific that a white space
(or lack of it); consider what happens when you are given the following HTML snippet:
<p>click this: <b>http://yourdomain.com/something</b>
depending on the processing you do to the text prior to linkifying
(made that word up!) this may not be relevant.
just jump over it.
Thanks for the suggestion!
