There's a lot you don't say about how much variation might occur in your data. But here's some code: 
#!/usr/bin/perl -w
use strict;

# Dummy up some data
my $html_page = <<END_HTML;
<html>
<head><title>My test page</title></head>
<body>
Stuff stuff stuff
<a href="/f1/show?page=matchup&lid=206&week=8&mid1=2&mid2=4">
Grut garble glump
<a href="/f1/show?page=matchup&lid=206&week=13&mid1=11&mid2=8">
Anderanda manda ander
<a href="/f1/show?page=matchup&lid=206&week=4&mid1=7&mid2=7">
Bottom
</body>
</html>
END_HTML

# if  you KNOW the bits will always be in the order above...
while ( $html_page =~ /&week=(\d+)&mid1=(\d+)&mid2=(\d+)/g ) {
   my ($week, $mid1, $mid2) = ($1, $2, $3);
   print "week[$week] mid1[$mid1] mid2[$mid2]\n";
   # do stuff
}

# if the bits can occur in any order...
while ( $html_page =~ /(<a[^>]+>)/g ) {
   my $anchor_txt = $1;
   my ($week, $mid1, $mid2);
   my $found_all = 1;
   unless ( ($week) = $anchor_txt =~ /week=(\d+)/ ) {$found_all = 0}
   unless ( ($mid1) = $anchor_txt =~ /mid1=(\d+)/ ) {$found_all = 0}
   unless ( ($mid2) = $anchor_txt =~ /mid2=(\d+)/ ) {$found_all = 0}
   if ($found_all) {
      print "week[$week] mid1[$mid1] mid2[$mid2]\n";
      # do stuff
   }
   else {
      print "Oops! Missing bit or extraneous tag.\n"; 
   }
}

The link extractor   $html_page =~ /(<a^>+>)/g   is not safe for all purposes. But it is a bit more robust than Chady's quick-and-dirty grabber which assumes that the complete text of only one tag will appear on any one line. From the looks of it, it's likely that the one-line proviso is fine for your data.

If the solutions proposed so far are not flexible enough to handle your data, give another holler...

Hope this helps. David
