Is this possible using just regular expressions?
The general idea is to match text in capturing parens and then refer to that text using $1, $2, etc. in the replacement expression: s/X(.*)X/Y$1Y/; # changes "Xfoo barX" to "Yfoo barY" perldoc perlre (search for "backreference") for all the poop. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
