Please observe the code snippet:

POST http://localhost/KRA/ASPDOTNET/DataService.asmx HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type:
application/soap+xml;charset=UTF-8;action="http://localhost/ASPDOTNET/XmlDataProcessing"
User-Agent: Jakarta Commons-HttpClient/3.1
Host: localhost
Content-Length: 472

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope"
xmlns:ihut="http://localhost/ASPDOTNET">
<soap:Header>
<ihut:UserCredentials>
<ihut:Username>dseadmin</ihut:Username>
<ihut:Password>adsfasdf</ihut:Password>
</ihut:UserCredentials>
</soap:Header>
<soap:Body>
<ihut:XmlDataProcessing>
<ihut:argstring>
<x>y</x>
</ihut:argstring>
</ihut:XmlDataProcessing>
</soap:Body>
</soap:Envelope>

I am getting error message as:
Data at the root level is invalid. Line 1, position 1

I need to pass <x>y</x> instead of y.

The web method is declared as XmlDataProcessing(XMLElement argstring)

Is there any workaround to fix this problem.

Thank you

Regards
Raj

That sounds like an error message of an XML parser but you have not
shown any code using an XML parser respectively you have not explained
what exactly you do with C# when you get that error.
The code you show above is some XML preceded by some HTTP request
headers. How does your C# code look? How do you send above to your web
method?
One explanation for that error would be that the XML parser parses the
HTTP headers you have shown.
