i love...
Spin the bottle
Redneck hoe
<br><br> <a href="http://den.com&qu
ot;>A</a>
http://www.google.com
loves ICP songs

and the result should be

i love...<br>
Spin the bottle<br>
Redneck hoe<br>

The real problem is finding a suitable regular expression,
which is a
little off topic for this list. For my (simple) purposes
this is
sufficient:

 r"""(?P<url>!?([a-z]+://[^ ]+[^.,'
)]}]))""",

To avoid substitution inside existing html tags you'll have
to limit
to strings of the form (^|>)[^<]*(<|$) I guess.

What you're asking is much trickier than you might think. 
Consider this
snippet:
   iron  < brass  < br >   <brrr!>
How will you know that the first and third "<"
should be turned in to
"&lt;" while the second one should be left as
a tag?

Arnar the 2 regexes u ve given me seem good how to do
         To avoid substitution inside existing html tags
you'll have
to limit to strings of the form (^|>)[^<]*(<|$) I
guess.

Thanks
