problem with Transforming dynamically generated xmll

R

reed.emmons

I'm trying to load and transform dynamically created xml. It works
great in IE but in Mozilla, it will not transform. I discovered that
when I copy the generated xml into a flat file, it works.

It might be caused by the function that processes the XML was called
before the xml document was completely loaded, though I don't know how
to resolve that.

Any ideas?

<html>
<head>
<script>
function loadXMLDoc(fileName)
{
var xmlDoc;
// code for IE
if (window.ActiveXObject){
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
}
else if (document.implementation &&
document.implementation.createDocument){
xmlDoc=document.implementation.createDocument("","",null);
}

xmlDoc.async=false;
xmlDoc.load(fileName);

return(xmlDoc);
}

function loadInventory()
{
xml=loadXMLDoc("/inventory/inventoryXML");
xsl=loadXMLDoc("/xsl/inventory.xsl");

// code for IE
if (window.ActiveXObject){
ex=xml.transformNode(xsl);
document.getElementById("inventory").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("inventory").appendChild(resultDocument);
}
}
</script>
</head>
<body onLoad="loadInventory()">
<div id="inventory"></div>
</body>
</html>

You will need to show a minimal but complete sample of the XML and XSLT
demonstrating the problem. Make sure that the server sends the HTTP
Content-Type: application/xml header for your XML as otherwise Mozilla
does not build an XML DOM document at all.

function loadXMLDoc(fileName)
{
var xmlDoc;
// code for IE
if (window.ActiveXObject){
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
Click to expand...

Note that only Msxml2.DOMDocument.3.0 and later (e.g.
Msxml2.DOMDocument.4.0, 5.0, 6.0) support XSLT 1.0 while
Microsoft.XMLDOM might give you a DOM document that does not support
XSLT 1.0.
// code for Mozilla, Firefox, Opera, etc.
else if (document.implementation &&
document.implementation.createDocument){
Click to expand...

If you want to use XSLTProcessor then why do you check for other
unrelated objects? I strongly suggest to check
if (typeof XSLTProcessor != 'undefined')
xsltProcessor=new XSLTProcessor();
xsltProcessor.importStylesheet(xsl);
resultDocument = xsltProcessor.transformToFragment(xml,document);
document.getElementById("inventory").appendChild(resultDocument);
}
Click to expand...

I don't see anything wrong with the code that would cause it to fail, as
said, show us the XML and XSLT and we can tell you more.

Have you checked that your application sends the HTTP
Content-Type: application/xml
header for the dynamically generated XML? That is necessary with Mozilla
to build a DOM with the load method.


<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/
Transform">

As you want to generate a HTML fragment to be included into a HTML div
element I suggest to set
<xsl:template match="/">
<html>
<body>
Click to expand...
^^^^^^
Throw them out, it does not make sense to have them for your case where
the result of the transformation is a fragment to be inserted into a div.

Ouch, of course, I didn't set the Content-Type.

Thanks a million; who knows when I would have figured that one out!
Cheers,
