Grep Challenge 2001

Hello everyone! Here's my grep challenge. Turn: <!--begin variable: variable_blah--> blah blah blah blah blah blah blah blah <!--begin variable: variable_blah2--> blah 2 blah 2 blah 2 blah 2 blah 2 blah 2 blah 2 blah 2 into: (variable_blah) (blah blah blah blah blah blah blah blah) (variable_blah2) (blah 2 blah 2 blah 2 blah 2 blah 2 blah 2 blah 2 ) Where the "blahs" (that are not part of the variable name) contain practically anything but the next comment "<!--begin variable:". Also the "blahs" maintain their \n and such (I just flattened those values out for demo purposes here). I've tried:"/<!--begin variable:?([\w\s]*)-->([\w\s]*)/m", but that misses out on any punctuation and "/<!--begin variable:?([\w\s]*)-->(.*)/m" gives me some other weirdness-- it doesn't find anything at all for the second substring. Any suggestions! Thanks cowboys! Sondra
