Subject: Re: AW: Not an FAQ:
still unable to validate against XSD

Please respond to
xerces-j-user
I just signed up to this list and stumbled accross this thread which
illustrates exactly (as far as I can tell) the problem I'm having.
Furthermore, I do not accept this solution (even if it works) as a valid
"fix" to the problem. The fact remains that namespace-enabled schemas
are not being processed correctly when referenced normally within an XML
document. My example that doesn't work is as follows:
Schema:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://schemas.gridforum.org/gridServices/rsl";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:rsl="http://schemas.gridforum.org/gridServices/rsl";
xmlns="http://schemas.gridforum.org/gridServices/rsl";
version="0.2">
<xsd:element name="rsl" type="rslType"/>
<xsd:complexType name="rslType">
<xsd:sequence>
<xsd:element name="job" type="xsd:string" minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
Document:
<?xml version="1.0" encoding="UTF-8"?>
<rsl
xmlns:rsl="http://schemas.gridforum.org/gridServices/rsl";
xmlns="http://schemas.gridforum.org/gridServices/rsl";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="
http://schemas.gridforum.org/gridServices/rsl
schema/test.xsd">
<job> Bastard! </job>
</rsl>
Xerces code:
DocumentBuilderFactory parserFactory = null;
DocumentBuilder xmlParser = null;
try {
parserFactory = DocumentBuilderFactory.newInstance();
parserFactory.setNamespaceAware(true);
parserFactory.setValidating(true);
xmlParser = parserFactory.newDocumentBuilder();
xmlParser.setErrorHandler(this);
} catch (javax.xml.parsers.ParserConfigurationException pce) {
logger.error("problem getting parser factory instance", pce);
return null;
}
BufferedReader bufferedReader = new BufferedReader(xmlReader);
return xmlParser.parse(new InputSource(bufferedReader));
I would really appreciate some feedback on this as my project is
basically stalled until I get this resolved.
Thanks,
Peter
