Regular Expressoin Help

[Anon]

I'm trying to parse a very complex dictionary file... Here's a sample of the data (this is one of the very simple lines):

<key>uel2.06:xanax<cw>Xanax<ent><me>Xan&syl;ax</me><pron>(zan&prim;aks),</pron><pdef><lab>Pharm. Trademark.</lab></pdef><def cat='PHA,TRM'>a brand of alprazolam.</def></ent></cw></key>

I'm trying to develop a regular expression that will capture the starting key, the data in the middle, then the ending key.
So far, I've got this:

$reNode = "(<[^>]>)";
$reData = "(.)";
$reEndNode = "(</[^>]*>)";
$reCheck = $reNode.$reData.$reEndNode;

This works fine the first couple of times through this loop:

do
{
ereg($reCheck, $data, $test);

echo $test[1]."\n";
echo $test[2]."\n";
echo $test[3]."\n\n";

$data = $test[2];

} while ($test[1] != "" AND $test[2] != "" AND $test[3] != "")

It doesn't break u ntill it get's to the tag <me>. Then it skips over the end tag </me> and grabs the end tag </pron>.

Any help would be very appreciated.

I guess what I'm asking is this: is there any way that I can tell $reEndNode to find "</(the first match's innards)>"?

It just made sense to me why it doesn't break untill it get's to <me>. <me> is the first tag that doesn't have it's ending </me> tag at the very end of the line... Ack...
