I am trying to work with some XML (a SOAP -> WSDL service request)

  • 0

I am trying to work with some XML (a SOAP -> WSDL service request) in which I have an XML schema with the namespace like:

NWMLS:EverNet:ImageQuery:1.0

<xs:schema id="ImageQuery_1.0" 
    targetNamespace="NWMLS:EverNet:ImageQuery:1.0"
    xmlns="NWMLS:EverNet:ImageQuery:1.0"
    xmlns:mstns="NWMLS:EverNet:ImageQuery:1.0" 
    xmlns:xs="http://www.w3.org/2001/XMLSchema" 
    attributeFormDefault="qualified" elementFormDefault="qualified"> ...remainder of xsd...

I keep getting this error from the web service I am requesting:

Could not find schema information for the element 'NWMLS:EverNet:ImageQuery:1.0:ImageQuery'.

Can someone please help me understand formatting namespaces like this, and perhaps point me to some reading? I have been looking for several hours. Thanks!

    A construct like xmlns:mstns=”NWMLS:EverNet:ImageQuery:1.0″ is mapping from a prefix (mstns) to a namespace URI (purported to be NWMLS:EverNet:ImageQuery:1.0).

    RFC2396 defines the syntax or a URI. What you have here is a perfectly valid non-hierarchical URI with a scheme of NWMLS.

    Your error message indicates that you just don’t have a W3C XML Schema with targetNamespace of the URI. The URI is just a string that uniquely identifies the schema.

    It has nothing to do with the syntax or format. In fact, it has a very simple syntax: NWMLS is the scheme, and everything else is just an opaque lump.
