If this is from a tutorial, you need to find another tutorial :) /(<.*>)/i; 1. Capturing text without checking for success or failure ($1 is not changed on no match, so it retains it's previous value). 2. Useless use of /i The last two lines would be better written as: /(<.*>)/ && print "Found it ! $1\n"; or, more readable: print "Found it ! $1\n" if /(<.*>)/; -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
