xpath query causing System.Web.Serv ices.Protocols. SoapException

7 New Member
I have a web service that receives an xml Node and xpath and should send back the matching node. My code works fine, the only problem is when the matching node is an XmlAttribute then it throws the following exception:

System.Web.Serv ices.Protocols. SoapException: Server was unable to process request. ---> System.InvalidO perationExcepti on: There was an error generating the XML document. ---> System.InvalidO perationExcepti on: Cannot write a node of type XmlAttribute as an element value. Use XmlAnyAttribute Attribute with an array of XmlNode or XmlAttribute to write the node as an attribute.

This is the xmlNode the server receives :
"<r xmlns=''> <a x='alpha'>aa <x>beta</x> cc</a> <b/> <a>AAA</a> </r>",
And xpath is “r/a/@x”
it returns an array of xmlNode
foreach (XmlNode matchingNode in list)
nodeResult[i] = matchingNode ;
Can anyone help me to solve this problem please?

Now I get the message when I try to run just my webservice...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
