[ http://issues.apache.org/jira/browse/XERCESC-1441?page=all ]
Alex Dickinson updated XERCESC-1441:
------------------------------------
Attachment: qname-good.xml
qname-bad.xml
qname.xsd
Attaching three files:
qname-good.xml - an XML file that will properly validate against qname.xsd
qname-bad.xml - an XML file that will should validate against qname.xsd, but
does not
qname.xsd - a schema definition defining QName based enumerated types
> QNameDatatypeValidator does not resolve namespaces when making comparisions

> Key: XERCESC-1441

> Project: Xerces-C++
> Type: Bug
> Components: Validating Parser (Schema) (Xerces 1.5 or up only)
> Versions: 2.6.0
> Environment: Linux 2.4.21-27 i686 GNU/Linux
> gcc (GCC) 3.2.3 20030502 (Red Hat Linux 3.2.3-49)
> Reporter: Alex Dickinson
> Attachments: QnameTest.cpp, qname-bad.xml, qname-good.xml, qname.xsd

> Xerces-C can not properly validate enumerations with a QName base.It will
> validate only if the enumeration's QName's prefix is exactly the same as the
> namespace prefix defined in the XSD.
> For example, the schema is defined as:
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
> xmlns:tns="http://www.example.com/qname";
> xmlns:xml="http://www.w3.org/XML/1998/namespace";
> targetNamespace="http://www.example.com/qname";
> elementFormDefault="qualified" > ...
> (the full schema is included below)
> Then the XML document will validate (using same namespace prefix):
> <tns:Body xmlns:tns="http://www.example.com/qname";
> xmlns:xml="http://www.w3.org/XML/1998/namespace";>
> <tns:Fault>
> <tns:Code>
> <tns:Value>tns:Sender</tns:Value>
> </tns:Code>
> </tns:Fault>
> </tns:Body>
> But the following will not (using a different namespace prefix):
> <my-tns:Body xmlns:my-tns="http://www.example.com/qname";
> xmlns:xml="http://www.w3.org/XML/1998/namespace";>
> <my-tns:Fault>
> <my-tns:Code>
> <my-tns:Value>my-tns:Sender</my-tns:Value>
> </my-tns:Code>
> </my-tns:Fault>
> </my-tns:Body>
> I have tracked the root of this problem down to
> trunk/src/xercesc/validators/datatype/QNameDatatypeValidator.cpp line 185:
> for ( ; i < enumLength; i++)
> {
> if (XMLString::equals(normContent, getEnumeration()->elementAt(i)))
> break;
> }
> if (i == enumLength)
> ThrowXMLwithMemMgr1(InvalidDatatypeValueException,
> XMLExcepts::VALUE_NotIn_Enumeration, content, manager);
> The comparison XMLString::equals is comparing the QName string with the URI
> prefix (i.e. tns:Sender) instead of the the URI itself (i.e.
> {http://www.example.com/qname}:Sender). So if the XML uses a different
> namespace prefix than that of the schema definition, it will fail.
