Problem in Matching XML Derived Types

whelanj · December 9th, 2009, 04:03 PM

Hello,
I had been under the impression that tests for things like "element(*, jsw:x)" would match when the current node was either of type jsw:x or derived from it. However, in at least one example (using SaxonSA 9.1.0.6), this doesn't seem to be working for me. Any advice as to what I am doing wrong? (details follow below.)
Thanks in advance.
Regards,
John

I'm expecting output of:

Code:

rootelem is NOT of type jsw:x.
A is of type jsw:x.
B is of type jsw:x.
C is NOT of type jsw:x.

But seeing output of:

Code:

rootelem is of type jsw:x.
A is NOT of type jsw:x.
B is NOT of type jsw:x.
C is NOT of type jsw:x.

My XSL is:

I seem to be unable to post the whole example. I'll look to add it ane part at a time...

The XSD for my input is:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns="http://www.company.com/whelan" 
xmlns:xs="http://www.w3.org/2001/XMLSchema" 
targetNamespace="http://www.company.com/whelan">
  <xs:complexType name="w">
   <xs:sequence>
    <xs:element ref="A"/>
    <xs:element ref="B"/>
    <xs:element ref="C"/>
   </xs:sequence>
  </xs:complexType>  
 <xs:element name="rootelem" type="w"/>
 <xs:element name="A" type="x"/>
 <xs:element name="B" type="y"/>
 <xs:element name="C" type="z"/>
 <xs:simpleType name="x">
  <xs:restriction base="xs:string"/>
 </xs:simpleType>
 <xs:simpleType name="y">
  <xs:restriction base="x"/>
 </xs:simpleType>
 <xs:simpleType name="z">
  <xs:restriction base="xs:string"/>
 </xs:simpleType>
</xs:schema>

Your test test="element(*, jsw:x)" is equivalent to test="child::element(*, jsw:x)" - it tests whether the context item has a child of that type, not whether it is itself of that type. You want test=". instance of element(*, jsw:x)", or test="self::element(*, jsw:x)".
