RE: Regex search using scalar
The search patterns I am looking for are contained inside the list (each element of the list is going to be used to scan an entire log file). So "if ( /match/ )" needs to reference each element of the FOREACH loop which I will have nested inside a while loop. That's what's confusing me. -Original Message- From: news [mailto:[EMAIL PROTECTED] On Behalf Of Tore Aursand Posted At: Wednesday, November 05, 2003 5:12 AM Posted To: Perl Conversation: Regex search using scalar Subject: Re: Regex search using scalar On Tue, 04 Nov 2003 20:41:17 -0800, Paul Harwood wrote: > I would like to enumerate a list and search through each element like > so: > [...] Why do you want to enumerate the list?
