Javascript - Visually Format Remote Server XML Query Response?

I'll preface this by stating I am a rank amateur when it comes to web dev.

I have a web appliance that provides XML data when issued a query string such as:

[URL]

I created a simple form that allows users to modify values of this query and have the appropriate XML returned. Here is that form:

<form id= "report" action="https://mysite.com/api/reporting.ns?" name="report">
Username: <input name="username"><br />
Password: <input type="password" name="password"><br />
<input type="hidden" name="generate_report" value="SupportSession">
Start Date: <input name="start_date">
<input type="hidden" name="duration" value="0">
<input type="hidden" name="limit" value="all">
<input type="submit" value="Show Report">

What I have not been able to accomplish is formatting that XML response so it looks pretty.

I have created an XSLT that formats the XML nicely and have used javascript to transform the XML using the XSLT like this:

function loadXMLDoc(dname)
{
if (window.XMLHttpRequest)
{
xhttp=new XMLHttpRequest();
}
else
{
xhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.open("GET",dname,false);
xhttp.send("");
return xhttp.responseXML;
}
function displayResult()
{
xml=loadXMLDoc("Report.xml");
xsl=loadXMLDoc("Report.xsl");
// code for IE
if (window.ActiveXObject)
{
ex=xml.transformNode(xsl);
document.getElementById("content").innerHTML=ex;
}
// code for Mozilla, Firefox, Opera, etc.
else if (document.implementation && document.implementation.createDocument)
{
xsltProcessor=new XSLTProcessor();
xsltProcessor.importStylesheet(xsl);
resultDocument = xsltProcessor.transformToFragment(xml,document);
document.getElementById("content").appendChild(resultDocument);
}
}

Which works locally but I run up against the cross domain security problem as the web appliance is hardened and I am not able to place any code on it.

I have been searching this site and the web for a couple days looking for a method to accomplish this using other means [asp?] and have been largely unsuccessful. The main reason this is so is that I don't know asp so I'm not sure how to attack it.

I think creating the query string in a form, then loading the resulting xml response from the web appliance to a string and applying the XSLT that resides on the server to it might be an option but haven't been able to make it work; again because I'm not really sure what I'm doing.

Here is my XSLT:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<div class="contentBox"> -->

[Code].....

Further information:

I found a way in asp to retrieve remote xml that works for URL's like http://site.com/file.xml but doesnt work for my URL. Maybe because it is a query? I've looked at way to encode/encapsulate my URL but haven't found anything that works.
