Sounds like you need a HTMLEncode function, you should take
a look at:

If you are just interested in adding the HREF link, then look at
the last line in that function.

str = str.replaceAll("((https?|ftp)://|mailto:)[^\\s<]+", "<A
HREF=\"$0\">$0</a>");

Good luck,

Matt

This is more of a javascript question actually, but take a look at:

Well the easy answer would be to simple extend the regular expression
like so:
str = str.replaceAll("((https?|ftp)://|mailto:)[^\\s<]+", "<A
TARGET=\"_new\" HREF=\"$0\">$0</a>");

should do.

lets say the text is "(www.blahblah.com)"
the code will include the ")" at the end of the string. Anyone know a
way around this?
