XSD with Namespacing

davidjlowry · June 15th, 2006, 03:53 AM

Hi All

I really hope you can be of some assistance!

I'm currently working on an XML producing C# component. It uses a WSDL and an XSD (thru MS' xsd.exe and wsdl.exe) to create a proxy by which the XML is sent.

I can produce clean valid XML, but I cannot work out how to get namespaces into the code.

This is my XML:

Code:

 <?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
 xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
 .....
    <API>CREATE_ARR_ARRANGEMENT</API>
  </MSG_HEADER>
  <MSG_BODY>
    <CreateArrearsArrangement>
      <accountPaymentReference>71335</accountPaymentReference>
      <startDate>2006-02-13</startDate>
  .....

And FYI this is what the Service provider states I should be sending

Code:

<?xml version="1.0" encoding="UTF-8"?>
......
     <ng0:API>CREATE_ARR_ARRANGEMENT</ng0:API>
</ng0:MSG_HEADER>
<ng0:MSG_SOAP_HEADER/>
<ng0:MSG_BODY>
   <ng1:CreateArrearsArrangement>
      <ng1:accountPaymentReference>71335</ng1:accountPaymentReference>
      <ng1:startDate>2006-02-13</ng1:startDate>
 .....

Here is some of the XSD code.

Code:

 <xs:element name="CreateArrearsArrangement">
    <xs:annotation>
    </xs:annotation>
    <xs:complexType>
      <xs:sequence>
        <xs:element name="accountPaymentReference" type="xs:date">
          <xs:annotation>
            <xs:documentation>This is the Pay....</xs:documentation>
          </xs:annotation>
        </xs:element>
        <xs:element name="startDate" type="xs:date">
          <xs:annotation>
            <xs:documentation>This is the Sta....nt</xs:documentation>
          </xs:annotation>
        </xs:element>

You can see above there is this:

Code:

<xs:element name="CreateArrearsArrangement">

I have tried setting this to:

Code:

<xs:element name="ng1:CreateArrearsArrangement">

and:

Code:

<xs:element name="ng1:CreateArrearsArrangement" ref="ng1:CreateArrearsArrangement">

but to no avail. I can't use ref on it's own all the time, because for most elements I require the type="" attribute to be set.

Does anyone have experience using namespaces in XSDs? Google for once is just evading being helpful!!

The "name" attribute of a component defined in a schema (e.g. an element) is always a local name: it is implicitly qualified by the targetNamespace defined on the xs:schema element. You can choose whether locally-declared elements (an xs:element within xs:complexType) should be in the target namespace or in no namespace by using the elementFormDefault attribute on xs:schema. Globally-declared elements (xs:element directly within xs:schema) are always in the target namespace.
