Title: regexp doesnt work for me

Something is wrong with this Regexp. 1)(?:(?:(?:http|ftp|gopher|telnet|news)://)(?:w{3}\.)?(?:[a-zA-Z0-9/;\?&=:\-_\$\+!\*'\(\|\\~\[\]#%\.])+) 2)(?:(?:(?:http|ftp|gopher|telnet|news)://)(?:w{3}\.)?(?:[a-zA-Z0-9/;\?&=:\-_\$\+!\*'\(\|\\~\[\]#%\.])+)) firstly: at 1 is the postet regexp. but i think there need to be placed at least an additional right parenthesis to close the first parenthesis (2) secondly: look at this part at the end: (?:[a-zA-Z0-9/;\?&=:\-_\$\+!\*'\(\|\\~\[\]#%\.])+) theres a beginning square bracket inside. behind the closing square bracket is a right parenthesis. the corresponding left parenthesis is inside the squared bracketing. so u have a wrong nesting. anyway: this regexp doesnt work for me. it generates syntax errors.
