XmlReader Hangs

[Shivonne]

Hi all

Having problems with the XmlReader object. I'm trying to
transform an XML document with XSLT - and get the
resulting output. My code is as follows:

XsltArgumentList xslArgs = passParameters
(xmlMenu.SelectSingleNode("document/setup")); // just a
local function to get all parameters in the doc
XslTransform xslTransform = new XslTransform();
MemoryStream memStream = new MemoryStream();
XmlTextWriter xmlWriter = new XmlTextWriter(memStream,
System.Text.Encoding.UTF8);
XmlDataDocument xmlXslt = new XmlDataDocument();
System.Security.Policy.Evidence evidence = new
System.Security.Policy.Evidence();
XmlUrlResolver xmlResolver = new XmlUrlResolver();
XmlReader xmlReader = null;

xmlXslt.Load(httpContext.Current.Request.MapPath
("xslt\\topneat.xslt"));
StringReader sr = new StringReader(xmlXslt.OuterXml);
XmlTextReader styleReader = new XmlTextReader(sr);
xslTransform.Load(styleReader, xmlResolver, evidence);
xmlReader = xslTransform.Transform(xmlMenu.CreateNavigator
(), xslArgs, xmlResolver);

xmlReturn.Load(xmlReader);
xmlReader.Close();
memStream.Close();

return xmlReturn;
It worked fine once - and now it hangs after the
xmlReturn.Load(xmlReader); line. My asp_wp process hogs
all the memory so something has gone wrong somewhere.

Can someone help me with this please? Is there something
I need to close at the end of the call?

Any help is much appreciated.

Thanks as always
