RE: How to get minOccurs and maxOccurs values from Element Declarations

[Wax, Ed]

Stella,

It is not as straight forward as one might image.  Assuming you have
navigated to a complex type:

 

XSComplexTypeDefinition complex;   // is set to the current complex
type.

 

XSParticle p = complex.getParticle();

XSTerm term = p.getTerm();

XSModelGroup xm = (XSModelGroup)term;

XSObjectList xobj = xm.getParticles();

 

for (int i = 0; i < xobj.getLength(); ++i) {

    XSParticle xp = (XSParticle)xobj.item(i);

    XSTerm t = xp.getTerm();

    if (t instanceof XSElementDeclaration) {

        XSElementDeclaration elem = (XSElementDeclaration)t;

 

        // At this point we know the particle is an element.

        // Here we can query for optionality info from the partical.

        if ( xp != null ) {

            isOptional = xp.getMinOccurs() == 0;

            // Check here for MaxOccurs as well.

        }

    }

}

 

Hope this helps.

 

Ed

Subject: How to get minOccurs and maxOccurs values from Element
Declarations

 

Hi,

I would like to ask how one can retrieve the minOccurs and maxOccurs
values from an element declaration (whether it is is a simple type or is
referring to a simpleType/complexType).
>From what I've found in the Xerces API, getMinOccurs() and
getMaxOccurs() are only defined in XSParticle. 

Would greatly appreciate if someone could point me in the right
direction!

Thanks,
Stella
