RES: Getting MaxOcurrs/MinOcurrs

Max,

I tried using Xsparticle, but I´ve must been doing something wrong, cause
I always get max = 1, min = 1 and maxunbounded = false. My code, xml and
schema are bellow, please take a look. Another doubt that I have is that
it´s possible to define maxOccurs to simpletype elements, but you can only
retrive XSparticle within XSComplexTypeDefinition

Thanks,

Rubens

Here´s the code :

public XMLtest() {
try
{
DOMParser parser = new DOMParser();

parser.setFeature("http://xml.org/sax/features/validation",true);

parser.setFeature("http://apache.org/xml/features/validation/schema",true);

parser.setProperty("http://apache.org/xml/properties/dom/document-class-name
",
"org.apache.xerces.dom.PSVIDocumentImpl");
parser.parse("C:/SGS/test/test.xml");
doc = parser.getDocument();
}
catch (SAXException sxe)
{
// Error generated by this application
// (or a parser-initialization error)
Exception x = sxe;
if (sxe.getException() != null)
x = sxe.getException();
x.printStackTrace();
}
catch (IOException ioe)
{
// I/O error
ioe.printStackTrace();
}

//buildForm(doc.getDocumentElement());
check(doc.getDocumentElement());
}

private void check(Node node) {
XSTypeDefinition psvi = ((PSVIElementNSImpl)
node).getElementDeclaration().getTypeDefinition();

if (psvi.getTypeCategory() == XSTypeDefinition.COMPLEX_TYPE)
{
XSComplexTypeDecl c = (XSComplexTypeDecl) psvi;
System.out.println("Node Name : "+node.getNodeName());
XSParticle p = c.getParticle();
System.out.println("Max : "+p.getMaxOccurs());
System.out.println("Min : "+p.getMinOccurs());
System.out.println("Maxu: "+p.getMaxOccursUnbounded());
}
Node son = node.getFirstChild();

while (son != null)
{
if (son.getNodeType() == Node.ELEMENT_NODE)
check(son);
son = son.getNextSibling();
}
}

here´s the output :

Node Name : test
Max : 1
Min : 1
Maxu: false
Node Name : testc
Max : 1
Min : 1
Maxu: false
Node Name : testc
Max : 1
Min : 1
Maxu: false

Here´s the XML and Schema :

minOccurs, maxOccurs are members of XSParticle.
When you traverse XSModelGroup you get the list of particles (XSParticle).
Particle's term may reference to element declaration, if this is declaration
of your element of interest use XSParticle.getMinOccurs(),
XSParticle.getMinOccursUnbounded(), XSParticle.getMaxOccurs(),
XSParticle.getMaxOccursUnbounded() to get min/max occurences of element.
