Wow, thanks!

Processing the entire file at once is fine for what I'm trying to do.

Here's what I had written so far (I just started with Perl so be gentle):

open (IN, 'input.txt') or die "$!";
my $lines = do {local $/; <IN>};
close IN;

while ($lines =~ s/Key.+?value=(\d+).+?Screen:add.+?value=(\d+).+?Xml:
+sendRequest.+?value=(\d+).+?Xml:onResponse.+?value=(\d+).+?Xml:proces
+sing.+?value=(\d+)//s){

# then I would use $1 - $5
}

I'm not sure yet how to incorporate your solution into what I have, but perhaps I should do some more reading.

Also, to clarify, the file has multiple lines but the KEY and PATTERN values don't fall on their own line as my original example illustrates. I made it a bit too simplistic. It looks more like:

BLAH BLAH BLAH KEY blah blah blah
BlAH BLAH BLAH ABD KEY blah blah
asdf asdf asdf asdf
BLAH ASDF PATTERN blah blah
