You seem to be using XSLT 2.0 so this is definitely a case for regular
expressions.

I'm always a bit hesitant about pattern matching in the text - you have to
accept that there will be a proportion of wrong matches and that these will
irritate your users. (Microsoft Powerpoint seems to have a nasty habit of
highlighting XPath expressions and regular expressions as URL hyperlinks,
for example). So I think it's important (a) to be careful about it, and (b)
to be conservative.

A reasonable regex might be something like 

\s(http://|www)(\.[a-z0-9])+\.(com|org|net|ca|uk|fr|de|...)[^\s]*

but I'm sure one could improve it.
