your example would be easier to follow if enclosed in
<code></code> blocks.

It works similar to the PRE tags in HTML.

I imagine you were downvoted because the code is hard
to read: 
{ 
     while(/A\s+HREF\s*=\s*"(^"+)"/ig)
     {
          $foo{$1}=1;
     }
}
 
for(keys %foo)
{
     print "\n";
}

Is this the code you had in mind?
