I am new to Castor and am trying to traverse a schema the following way
(wrong I assume):
SchemaReader reader = new SchemaReader(new
FileReader("someSchema.xsd"),"someSchema.xsd");
Schema schema = reader.read();
Vector elementsV = new Vector(); /* a vector to put my ElementDecl's in */
for (Enumeration e = schema.getElementDecls(); e.hasMoreElements();) {
elementsV.add(e.nextElement());
ElementDecl elem = (ElementDecl) elementsV.lastElement();
System.out.println( "Element: " + elem.getName() );
if(elem.getType().isComplexType()) {
System.out.println( "\tType: Complex");
ComplexType temp = schema.getComplexType(elem.getName());
/* temp is always null */
}
else System.out.println( "\tType: Simple");
if(elem.hasChildren()) System.out.println( "\tHas Children");
else System.out.println( "\tHas no Children");
}
}
I have read a response to a mail where Keith Visco instructed to use
ComplexType#enumerate, although I cannot find out how to get the complex
types the schema contains. Once I have the ElementDecl's I can find no
way to return the ComplexType (if the ElementDecl has a ComplexType).
All I would like to do is traverse the schema finding the complex types
and their group definitions, atts, etc ....
If I am to do:
Enumeration e = schema.getComplexTypes()
The enumeration is empty. I am stuck, can anyone instruct me on the
proper methods to use to traverse a schema?
Here is a very simple schema I have been using:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:element name="person">
<xs:complexType>
<xs:sequence>
<xs:element name="full_name" type="xs:string"/>
<xs:element name="nick_name" type="xs:string" maxOccurs="10" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
How can I traverse this and determine element person is a complex type,
with a sequence of two elements named full_name, and nick_name that need
strings?
Thank you
Lloyd
