Question

I am trying to create an asp.net web form that allows a user to enter information, then have this information sent via an XMLwriter to a web service.

Here is a snippet of the xml as it should be outputted;

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
 <soap:Body xmlns:ns1="http://its/foo.wsdl">

I try to manipulate this via code;

xml.WriteStartElement("soap", "Envelope", "http://schemas.xmlsoap.org/soap/envelope/")     
xml.WriteAttributeString("xmlns", "ns1", "http://its/foo.wsdl")

But I get this error:

The 'xmlns' attribute is bound to the reserved namespace 'http://www.w3.org/2000/xmlns/'.

Can anyone tell me what I am doing wrong?

Thanks.

Answer 1

using (var writer = XmlWriter.Create(Console.Out))
{
    writer.WriteStartElement("soap", "Envelope", "http://schemas.xmlsoap.org/soap/envelope/");
    writer.WriteStartElement("soap", "Body", null);
    writer.WriteAttributeString("xmlns", "ns1", null, "http://its/foo.wsdl");
    // ... add other tags
    writer.WriteEndElement();
    writer.WriteEndElement();
}
