Stick an XML value into a variable for file writing

Hello all, I have a question that is complicated in explanation, but I think the solution is going to be like.. one word simple. I'm guessing.

Here's my situation. I have a pdf form developed in Adobe LiveCycle Designer, so it outputs XML values. You can set up a button to fire these values off to a PHP file so that the XML values can be processed.

I have both the form and the PHP file set up, but now I'm trying to write to a .txt file using a retrieved XML field "final1" and to turn the value of that into the contents of the .txt file. Let's look at some stuff.

The form

The .txt file
http://www.cyan-studios.net/posttest/smdownload.txt

The PHP code
Code:

<HTML>
<HEAD>
<TITLE>HTTP Request Dump</TITLE>
</HEAD>
<BODY>
<h1>HTTP Request Dump</h1>
This page sends back to you what your browser or other user-agent submitted to this page.

<h2>HTTP Headers</h2>
<pre>
<?PHP
DumpArray("HEADERS", emu_getallheaders());
?>
</pre>

<h2>Submitted Variables (as parsed by PHP)</h2>
<pre>
<?PHP
echo $content_type;
DumpArray("REQUEST",$_REQUEST);
?>
</pre>

<h2>Raw POST Body</h2>

<pre>
<?PHP
$body = file_get_contents("php://input");
echo strlen($body);
echo " bytes: <br>";
?>
<span style="background-color: #e0e0f0">
<?PHP
while (strlen($body)>60) {
echo substr($body, 0, 60);
echo "\n";
$body = substr($body, 60);
}
echo $body;
?>
</span>
</pre>

</BODY>
</HTML>
<?PHP

# Function DumpArray
##########################################################
function DumpArray($ArrayName,&$Array) {

foreach ($Array as $Key=>$Value){
echo "$Key:\n$Value\n";
} # End of foreach ($GLOBALS as $Key=>$Value)
} # End of function DumpArray
#################################################


function emu_getallheaders() {
foreach($_SERVER as $h=>$v)
if(ereg('HTTP_(.+)',$h,$hp))
$headers[$hp[1]]=$v;
$headers["CONTENT_TYPE"]=$_SERVER["CONTENT_TYPE"];
return $headers;
}

$myFile = "smdownload.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "Jallopy";
fwrite($fh, $stringData);
fclose($fh);

?>

You get something like this on the dump:

As you can see from my oh-so artistically fashioned diagram, I just want the value of key "final1", and I want to turn that into a variable. Then, I want to toss that variable in place of the word "Jallopy" in the above code (see the blue text).

Any help's appreciated and shall be rewarded with cake.
