Let me reiterate ... Unfortunately, you're not reiterating anything: none of the example strings you give is the same as any in the OP. I suggest you follow CountZero's approach and post something like I have the following patterns of data: `'name=servername.xyz.abc.coom'` `'name=servername'` `'name=servername.xyz.com'` `'whatever'` ... From each of these patterns I want to extract string. I think I know what you think you want, but why should we play guessing games? The devil is in the details. Update: Also, what version(s) of Perl must you work with? This has implications for the regex constructs that are available. Give a man a fish: `<%-(-(-(-<`	[reply] [d/l] [select]

Wait! You have just changed the data. Before it was of the general form "`name=servername ...`" and now it is "`servername ...`". Different forms of data will need different forms of regexes. Please provide some better information or our help will just be guesswork. CountZero A program should be light and agile, its subroutines connected like a string of pearls.

Let me reiterate what CountZero told you earlier `if ($string =~ m/name=([^.]+)/) { my $variable_i_am_interested_in = $1; }` [download]	[reply] [d/l]
