Thanks a lot for the mail... I have one more to clarify...The line you specified s/$openTag.*?$closeTag/New/g;
searches and replaces the tags with the word "New" fine.. My questions is if there is a line like $_= "This is a test for [%one_two%] number and [%pne%] numbers."; Is there in perl any operator which will help me to take the variable names separately like... one_two pne Thanks Anish ----- Original Message ----- From: "David le Blanc" <[EMAIL PROTECTED]> To: "Anish Kumar K." <[EMAIL PROTECTED]> Cc: "beginners perl" <[EMAIL PROTECTED]> Sent: Thursday, October 07, 2004 4:38 PM Subject: Re: Need Help > This is an example of perl regular expression greediness. > > check 'perldoc perlre' and search for "greediness". > > You might want to use something like > > s/$openTag.*?$closeTag/New/g > > the extra '?' does not mean what you think it means when it follows a + or a * > > :-) > > Sorry for the top post. > > > > On Thu, 7 Oct 2004 15:45:09 +0530, Anish Kumar K. > <[EMAIL PROTECTED]> wrote: > > Hi > > > > Please anyone help me in Reg Exp.
