Hey Guys,
Can you give me a hand. I'm getting a weird error that I cannot replicate with
jaxp.SourceValidator so I know I must be doing something wrong, but I can't
tell what.
My code looks like this:
package com.rackspace.xerces;
import javax.xml.validation.*;
import javax.xml.transform.stream.*;
public class Test {
public static void main(String[] args) {
if (args.length != 2) {
System.err.println ("Usage: need XSD and instance doc");
return;
}
try {
System.setProperty
("javax.xml.validation.SchemaFactory:http://www.w3.org/XML/XMLSchema/v1.1";,
"org.apache.xerces.jaxp.validation.XMLSchema11Factory");
String xsd = args[0];
String instance = args[1];
SchemaFactory factory =
SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1";);
factory.setFeature
("http://apache.org/xml/features/validation/cta-full-xpath-checking";, true);
Schema s = factory.newSchema(new StreamSource(xsd));
s.newValidator().validate(new StreamSource(instance));
} catch (Exception e) {
e.printStackTrace();
}
}
}
You pass a schema in param 1 and an instance document in param 2, the code
validates and returns errors. Here's the schema I'm using to test:
<schema
elementFormDefault="qualified"
attributeFormDefault="unqualified"
xmlns="http://www.w3.org/2001/XMLSchema";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:tst="http://www.rackspace.com/xerces/test";
targetNamespace="http://www.rackspace.com/xerces/test";>
<element name="e" type="tst:SampleElement"/>
<element name="a" type="tst:SampleAttribute"/>
<complexType name="SampleElement">
<sequence>
<element name="even" type="tst:EvenInt100" minOccurs="0"/>
</sequence>
</complexType>
<complexType name="SampleAttribute">
<attribute name="even" type="tst:EvenInt100" use="optional"/>
</complexType>
<!-- XSD 1.1 assert -->
<simpleType name="EvenInt100">
<restriction base="xsd:integer">
<minInclusive value="0" />
<maxInclusive value="100" />
<assertion test="$value mod 2 = 0" />
</restriction>
</simpleType>
</schema>
When I pass the following instance document, the assertion in EvenInt100 trips
and things fail as expected:
<a xmlns="http://www.rackspace.com/xerces/test"; even="23"/>
When I pass *this* instance document however, I'd expect the same assertion to
fail, but it doesn't.
<e xmlns="http://www.rackspace.com/xerces/test";>
<even>23</even>
</e>
The very weird bit is that jaxp.SourceValidator works correctly on the
example, so i must be doing something wrong...but I can't tell what it is. Any
ideas?
BTW my code is on github here:
https://github.com/RackerWilliams/xerces-tests/tree/master/schema_tests
You should be able to do a
mvn clean install
Then
java -jar target/xerces-test-1.0.0-SNAPSHOT-jar-with-dependencies.jar test.xsd
test.xml
to illustrate the issue.
Thanks,
