XSD problem

Question

Hi,
my assign command is failing for the following error:
<selectionFailure>
<part name="summary" >
<summary>empty variable/expression result. xpath variable/expression expression "/ns2:OrderXml/ns2:Envelope/ns2:Sender" is empty at line 31, when attempting reading/copying it. Please make sure the variable/expression result "/ns2:OrderXml/ns2:Envelope/ns2:Sender" is not empty. </summary>
</part>
</selectionFailure>
The xsi:noNamespaceSchemaLocation... (see below) was not added by me
as you can see the sernder node is not empty
i suspect something is wrong with my xsd file which starts like this:
<xs:schema attributeFormDefault="unqualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="myNS"
xmlns="myNS"
elementFormDefault="qualified">
<xs:element name="OrderXml">
<xs:complexType>
Any idea?
Thanks

Answer 1

Hmm. Just discovered that this is apparently because of the way I'm doing the namespacing: the following XSD and XML files work fine:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
     <xs:attribute name="code" type="xs:string"/>
     <xs:element name="foo">
          <xs:complexType>
               <xs:attribute ref="code" use="required"/>
          </xs:complexType>
     </xs:element>
     <xs:element name="body">
          <xs:complexType>
               <xs:sequence>
                    <xs:element ref="foo"  maxOccurs="unbounded"/>
               </xs:sequence>
          </xs:complexType>
     </xs:element>
</xs:schema>
<?xml version="1.0" encoding="UTF-8"?>
<body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="./test.xsd">
    <foo code="bar" />   
</body>Does anyone have any clue what the difference here is? What did I do wrong in my original files?
Thanks!
