Xml transformation to wml using asp.net

[shakthi]

Hi,

I am trying to transform an xml file to wml using asp.net. I get the
xml file from sql server as a string. so I need to convert it to xml
and tranform that xml file to wml.

Here is my code:

private void XmlTransformToWML(string hn_xml)
{
XmlDocument xmlDoc = new XmlDocument();

try
{
xmlDoc.LoadXml(hn_xml);
}
catch (XmlException e)
{
Response.Write(e.Message);
}
XPathDocument xpathDoc = new XPathDocument();

string xslPath = Server.MapPath("hnxml.xslt");


XslCompiledTransform myXslTrans = new XslCompiledTransform();
//Load the XSL stylsheet into the XslCompiledTransform object
myXslTrans.Load(xslPath);
myXslTrans.Transform(xmlDoc, null, Response.Output);
}

My problem is when I execute this code I am getting the following
exception. I have a doubt, can we use XmlDocument as a argument to
transform to wml.

Exception:

System.Xml.Xsl.XslTransformException: Attribute and namespace nodes
