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.
