Hello,
I'm frustrating myself terribly, trying to extract an URL using regular
expressions from the following string:
bla http://www.yahoo.com/blabla.html?this=insane - bla bla
Now how do I do that? I've tried and failed miserably, this is where I
got: (http://|www).*
Which prints out "http://www.yahoo.com/blabla.html?this=insane - bla
bla" - damn these regular expressions! Rebol's 'parse is way better for
this kind of thing, at least I can get 'parse to stop at the first
space!
Thanks in advance!
Regards,
Rachid
