I'm writing a filter/parsing function for texts entered by users, and
I've run into a problem...
What I'm trying to do is to parse URLs of different sorts, ftp, http,
mms, irc etc and format them as links, that part was real easy..
The hard part is when a user has already entered a complete link..
In short:
http://www.server.tld/page.html
should be converted to:
<a
href='http://www.server.tld/page.html'>http://www.server.tld/page.html</a>
That part works fine, but if the user enters:
<a href='http://www.server.tld/page.html'>click here</a>
it all becomes a mess... Can somebody please make a suggestion on this?
regular expressions - in particular a 'negative look behind' assertion.
here is a page that [trys to] explain it:

google given loads of hits for 'negative look behind', hopefully you
get somewhere - me I have too little time to right now to go into
examples. good luck
