microsoft.public.dotnet.framework.aspnet.webservices

error with namespace

RK

7/14/2003 6:24:00 PM

I created a small web service with a single method that
returns XmlElement back to the client. This method is
working fine if I return string using OuterXml property,
but when I am trying to return XmlElement it is throwing
error. could anybody give me hint, what could be the
problem..


thanx in advance
RK



webservice is something like this..

[WebService(Namespace="http://www.xyz.com/mySer...)]
public class myWebService:System.Web.Services.WebService
{

[WebMethod]
public XmlElement getXML(string strNumber)
{
XmlDocument objXML = new XmlDocument();
objXML.LoadXml("<topElement></topElement>");

/**nodeOne and nodeTwo are coming from dll
* component using some methods */

objXML.DocumentElement.AppendChild(nodeOne);
objXML.DocumentElement.AppendChild(nodeTwo);

return objXML.DocumentElement;

}

}

It is throwing an error like

System.InvalidOperationException: There was an error
generating the XML document. --->
System.ArgumentException: Cannot use a prefix with an
empty namespace.

LIAR!!!!!!!!!!!!!!!!!!!!!!!

"President Barack Obama proposed his 2011 budget during February 2010.
He has indicated that jobs, health care, clean energy, education, and
infrastructure will be priorities. Total requested spending is $3.83
trillion and the federal deficit is forecast to be $1.56 trillion in
2010 and $1.27 trillion in 2011."
