Good Day Honorable Monks,
I am attempting to use RegEx to match specific XML tags and can't seem to figure out why I can't get the results that I expect.
Here is an example xml doc: 

<ROOT hostname="bumblebee" tstamp="2011/09/21 22:24:05">
    <APPLICATION>
        <PORT>7777</PORT>
        <APP_HOME>/extra/localcw/opt/APP/sun4</APP_HOME>
        <VERSION>V36.11.01</VERSION>
        <PERF_HOME>/usr/localcw/opt/APP/Solaris-2-9-sparc-64</PERF_HOM
+E>
        <PERF_VERSION>glanceSunOS 5.9 (Solaris 9) (sparc, 64 Bit) 7.3.
+00.6059 Jul 19 2006</PERF_VERSION>
        <STAR_VERSION>3.0</STAR_VERSION>
        <DEFAULT_ACCT>root</DEFAULT_ACCT>
        <HISTORY_RETENTION>90</HISTORY_RETENTION>
        <LAST_FILE_DOWN>StAR-201105090928.tar</LAST_FILE_DOWN>
        <LAST_STATUS>No download file found</LAST_STATUS>
        <ACL>
            <ACCOUNT id="f9a64ef61c">
                <MD5>f9a64ef61c</MD5>
                <USERNAME>*</USERNAME>
                <HOST>flower</HOST>
                <PERMISSION>P</PERMISSION>
            </ACCOUNT>
        </ACL>
    </APPLICATION>
</ROOT>

So I have basically 5 different distinct XML tag formats to match against.

<openingTagName attribute="whatever">
<openingTagName>
<openingTagName>value</closingTagName>
<openingTagName></closingTagName>
</closingTagName>

But when trying to match against <openingTagName> only using something like the following it doesn't match what I would think it would namely <openingTagName> only like from the xml tags <APPLICATION> and <ACL>. But it doesn't. Can someone give me a hint or two on how to grab only <APPLICATION> and <ACL> which once realized should help me get through the others myself. 

foreach my $line (@xml)
{
  chomp($line);
  if($line =~ /^\s*<(\w+)>[^\w*|\d*|<]/)
  {
        print "$1\n";
  }
}

I would have thought the negate classes would have eliminated any and all values after the initial > but it doesn't. I have spent quite a while on different patterns but none work. Any and all suggestions will be greatly appreciated.

Thanks...
