Even viewing the xml version of your post (ie, the way you posted it), the code makes no sense... but first, let's check: Is this what you intended:
($IPADDR,$MACADDR,$OS,$OSDETL) = $TEXT =~ /(192\.168\.1\.[\d]+).*?([\d]2:[\d]2:[\d]2:[\d]2:[\d]2:[\d]2)/g;

but it doesn't work. It will work if I only use 

@matches = ( $TEXT =~ /(192\.168\.1\.[\d]+)/g);
foreach my $val (@matches) {
   print "$val\n";

But if I try to match another string in the same regular expression it fails. For example, this doesn't work:

@matches = ( $TEXT =~ /(192\.168\.1\.[\d]+).*?([\d]2:[\d]2:[\d]2:[\d]2:[\d]2:[\d]2)/g);

If that's what you tried to write, amended to close the code tags as kennethk suggested, why are you using character classes when \d would work and \d{2} might do what you want?

And not just BTW, were you specify \d+ the regex engine would any number of digits until some other character intervenes or it hits the end of the string... and .*? merely limits the number of matches to the dot (anything) to as few as possible before taking up with your [\d]2:s again.


Questions containing the words "doesn't work" (or their moral equivalent) will usually get a downvote from me unless accompanied by:
  1. code
  2. verbatim error and/or warning messages
  3. a coherent explanation of what "doesn't work actually means.
