Hi,
I am trying to use a SAXReader with a schema loaded into a
DatatypeDocumentFactory so that I can get properly typed data from the
getData() method of an Element. What I have found is that this only works
when a schema reference exists in an instance document. If I load the
schema using the loadSchema() method or use the SchemaParser it is simply
ignored.
I use the following code to parse and load the schema:
DatatypeDocumentFactory factory = new DatatypeDocumentFactory();
SAXReader reader = new SAXReader();
Document doc = reader.read(argSchemaLocation.toURL());
Namespace namespace = DocumentHelper.createNamespace(
"smclient",
"http://www.3eti.com/infomatics/schemas/sm_client_schema";);
factory.loadSchema(doc, namespace);
......
SAXReader reader = new SAXReader(factory);
Document doc = reader.read(argConfigURI.toURL());
I have an element called perMessageLogging with type xsi:boolean. When I
encounter an instance document like this:
<SMClientConfig
xmlns="http://www.3eti.com/infomatics/schemas/sm_client_schema";
xmlns:smclient="http://www.3eti.com/infomatics/schemas/sm_client_schema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.3eti.com/infomatics/schemas/sm_client_schema
../schemas/sm_client_schema.xsd">
<perMessageLogging>false</perMessageLogging>
</SMClientConfig>
Then I can use this to get the value as a Boolean
Element elem = (Element)
doc.selectSingleNode(
"/prefix:SMClientConfig/prefix:perMessageLogging"
.replaceAll("prefix", prefix));
if (null != elem)
{
perMessageLogging = ((Boolean)
elem.getData()).booleanValue();
}
However, when I remove the schemaLocation from the instance document like
this then it is returned as String:
<SMClientConfig
xmlns="http://www.3eti.com/infomatics/schemas/sm_client_schema";
xmlns:smclient="http://www.3eti.com/infomatics/schemas/sm_client_schema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<perMessageLogging>false</perMessageLogging>
</SMClientConfig>
It makes no difference whether I load the schema or not. The only thing
that matters is that the schemaLocation is set. Am I doing something wrong?
What is the point of loading the schema if it is not used?
Thanks,
Mark
