$catreg = "^(<[A-Za-z0-9]+>)*<H1>(<[A-Za-z0-9]+>)*([A-Za-z0-9]+)";
 Im a newbie...so if you respond, speak in English, not PERL, please. Be gentle!

The script Above is used to parse through at HTML document. In practice, what it is doing is getting the text between <H1> and </H1>. For instance, if it found <H1>ABCD</H1> , it would isolate and return ABCD.

This works most of the time, but for some combinations of letters, it does not work. Its very very wierd.

So, my question is..can someone explains what this line of code does? Again it is below.

$catreg = "^(<[A-Za-z0-9]+>)*<H1>(<[A-Za-z0-9]+>)*([A-Za-z0-9]+)";

PS...below is the later section of the code where it is REALLY used. The line I show above, i think, is sort of a variable declaration.

    if ( m!$catreg! ) {
    print "found(pre) $cat\n";
    print STDERR "checking for cat :$3:\n";
    $cat = $catlist{$3};
    print "cat == $cat\n";
    next;
    }
