AI am trying to call a third-party web service. this service expects an XML
fragment that contains the request plus other parameter. adding the web
reference created the syntax below(reference.vb).
I changed the data type for the structure that contains the XML data from
the default "String" to "xml.xmldocument" to enable easy filling of the
data.
my client code creates an XML document class, fills the data using standard
xml dom calls, and then invokes the web service.
the server refuses my call because the XML element below the root element
(customerGeneralInquiryRequests ) contains an empty "xmlns" attribute. How
do I get rid of it? I tried to define PDataXML as a node, explicitly declare
the namespace as "nothing" when calling "CreateElement", nothing helps!
attached: samples from the reference file, my code that fills the XML
framgment, the WSDL retrieved from the web serrver, and from the output
trace.
any help will be appreciated!
note: a second question. the process by which the "p0" and "PDataXML"
elements are created in the request body are unclear to me. can anyone
explain or refer to good explanations? thanks!

aRequest.PDataXML = aXMLDoc
Try
aResult = svc.CallService(aRequest)
