I am having some problems building a properly formatted SOAP message using XMLDocument in VB.NET(C# answers are fine though).
I am using the following code to manually create my SOAP message, what is happening is that the namespace prefix of the soap:Header and soap:Body are being stripped in the output XML:
Dim soapEnvelope As XmlElement = _xmlRequest.CreateElement("soap", "Envelope", "http://schemas.xmlsoap.org/soap/envelope/")
soapEnvelope.SetAttribute("xmlns:xsd", "http://www.w3.org/2001/XMLSchema")
soapEnvelope.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance")
_xmlRequest.AppendChild(soapEnvelope)
Dim soapHeader As XmlElement = _xmlRequest.CreateElement("soap", "Header", String.Empty)
_xmlRequest.DocumentElement.AppendChild(soapHeader)
Dim soapBody As XmlElement = _xmlRequest.CreateElement("soap", "Body", String.Empty)
_xmlRequest.DocumentElement.AppendChild(soapBody)
This results in the following output:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Header>
...
</Header>
<Body>
....
</Body>
</soap:Envelope>
What I need is:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soap:Header>
...
</soap:Header>
<soap:Body>
....
</soap:Body>
</soap:Envelope>
NOTE: I appreciate all input, but regardless of any references to how SOAP should work or be parsed on the receiving side or anything like that, the bottom line is I need to generate the XML as described for. Thanks in advance!
SOLUTION: Very similar to Quartmeister answer was the way I resolved this. The issue was in fact in relation to namespace. Rather than use the string value every time though, I used the following solution using the NamespaceURI of the DocumentElement:
Dim soapHeader As XmlElement = _xmlRequest.CreateElement("soap", "Header", _xmlRequest.DocumentElement.NamespaceURI)
Dim soapBody As XmlElement = _xmlRequest.CreateElement("soap", "Body", _xmlRequest.DocumentElement.NamespaceURI)
