var my_xml:XML = new XML("<highscore><name>Ernie</name><score>13045</score></highscore>");

This example indicates the XML data is sent to a coldfusion template, highscore.cfm. Could the code for this document be included somewhere in the documentation so users can see how to interpet the XML data in coldfusion? I have been unable to find any documentation as to how the XML data object sent from flash is usable with coldfusion.

The code for highscore.cfm is included below, and may be a bit basic, but it works.

<cfsetting enablecfoutputonly="Yes">
<cfscript>
success = true;
// sample packet: <highscore><name>Ernie</name><score>13045</score><highscore>
try {
switch (CGI.REQUEST_METHOD) {
case 'POST':
XmlRequest = getHTTPRequestData( ).content;
break;
case 'GET':
XmlRequest = CGI.QUERY_STRING;
break;
}
XmlRequest = XmlParse(XmlRequest);
Variables.name = XmlRequest.XmlRoot.name.XmlText;
Variables.score = XmlRequest.XmlRoot.score.XmlText;
} catch (Any e) {
errorMessage = e.Message;
success = false;
}
</cfscript>
<cfif success>
<cfoutput><h1>Congratulations to #Variables.name# who scored #Val(Variables.score)# points!</h1></cfoutput>
<cfelse>
<cfoutput><h2 style="color:##FF0000;">Unable to locate XML packet in either GET or POST scope.</h2>
<ul><li>#errorMessage#</li></ul></cfoutput>
</cfif>
<cfsetting enablecfoutputonly="No">

The code begins with a switch statement which determines how the data was submitted. If the CGI.REQUEST_METHOD is POST, the XML packet is passed in the HTTP request as #getHTTPRequestData().content#. If the CGI.REQUEST_METHOD is GET, the same XML would have been passed in the query string as CGI.QUERY_STRING.
Next you parse the XML string into a CF XML object using #XmlParse()# and the values are accessed using ColdFusion.

Hope that helps. The only real "trick" in the process is the #getHTTPRequestData()# which is explained in the ColdFusion documentation on LiveDocs at http://livedocs.macromedia.com/coldfusion/7/htmldocs/00000482.htm.

Notice that '&' caracter is replaced by its entity '&amp;' just before the sending.
So you can't send a simple textNode like XML("login=name&pass=word") to perform the same HTTP request that a <form method="POST"> do.
