Please see Writeup Formatting Tips -- your post will be easier to read if you use <p> and <br> to format your text, and use <code> and </code> tags to format your code, data, and results.

Update:Here's the best I could get out of your code as written; I am sure I mistranslated something in the effort to compensate for the lack of <code> and </code> tags.

#!/usr/bin/perl -w

use strict;

# ---------------[ Original request ]---------------
# I have a string: P7: "P7": place in [from Mem:0x5ffa5800 to Mem:0x60
+077fff]
# { I need to extract both Hex Values and subtract value 2 from value 
+2
# There are allot of ways to parse a astring and wanted to be a little
+ more elegant in the approach.
# I am not getting an matches at all with this and it should work.


my    $line = "P7: \"P7\": place in [from Mem:0x5ffa5800 to Mem:0x6007
+7fff]";
print "\$line = '$line'\n";

if ($line =~ m/"P7"\:/)
{
    print "\$line matches P7\n";
    if ( $line =~ /\(.*Mem:\)\(0x[0-9a-fA-F]*\)\( to Mem:\)\(0x[0-9a-f
+A-F]*\) )
    {
        print "First Value $2 \n";
        print "Second Value $4 \n ";
    }
    else
    {
        print "Did not match second test\n";
    }
}

exit;
