Java XML get the type of an element tag

Hi Forum,

I've a question regarding XML, Schema defined complex types and how to get the elements with a concrete type in my java app.

I've defined a schema which declares some complex types

Code:

---

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://xml.netbeans.org/schema/propertyTypes"
    xmlns:tns="http://xml.netbeans.org/schema/propertyTypes"
    elementFormDefault="qualified">   
    <xsd:complexType name="intproperty">       
        <xsd:attribute name="value" type="xsd:int" use="required"/>
        <xsd:attribute name="minValue" type="xsd:int" use="optional"/>
        <xsd:attribute name="maxValue" type="xsd:int" use="optional"/>
    </xsd:complexType>
</xsd:schema>

---

Furthermore I have written a schema which uses the schema above. This schema declares some kind of configuration

Code:

---

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://xml.netbeans.org/schema/ArchiveJob"
    xmlns:tns="http://xml.netbeans.org/schema/ArchiveJob"
    elementFormDefault="qualified" xmlns:ns1="http://xml.netbeans.org/schema/propertyTypes" xmlns:ns0="http://xml.netbeans.org/schema/job">
    <xsd:import schemaLocation="../genericpropertyprocessing/propertyTypes.xsd" namespace="http://xml.netbeans.org/schema/propertyTypes"/>
    <xsd:import schemaLocation="../genericpropertyprocessing/job.xsd" namespace="http://xml.netbeans.org/schema/job"/>
    <xsd:element name="ArchiveJob">
        <xsd:complexType>
            <xsd:complexContent>
                <xsd:extension xmlns:tns="http://xml.netbeans.org/schema/job" base="ns0:Job">
                    <xsd:sequence>
                        <xsd:element name="age" type="ns1:intproperty">
                            <xsd:annotation>
                                <xsd:documentation xml:lang="en">The amount of days after an action or message will be deleted</xsd:documentation>
                            </xsd:annotation>
                        </xsd:element>
                    </xsd:sequence>
                </xsd:extension>
            </xsd:complexContent>
        </xsd:complexType>
    </xsd:element>
</xsd:schema>

As you can see I use the type intproperty for the element named "age". Finally I wrote a XML document deduced from the schema above.

Code:

---

<ns0:ArchiveJob  xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
  xmlns:ns0='http://xml.netbeans.org/schema/ArchiveJob'
  xsi:schemaLocation='http://xml.netbeans.org/schema/ArchiveJob ArchiveJob.xsd' jobname="ArchivJob">
    <ns0:age value="1"/>   
</ns0:ArchiveJob>

Now to my question is it possible to get all elements with the type "intproperty" with java???

I've tried this

Code:

---

public static void main(String[] arg) {
        try {
            DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
            Document doc = docBuilder.parse(new File("ArchiveJob.xml"));
            doc.getDocumentElement().normalize();
            System.out.println("Root element of the doc is " + doc.getDocumentElement().getNodeName());
            NodeList listOfNodes = doc.getElementsByTagNameNS("*", "*");
            for(int i = 0 ; i<listOfNodes.getLength();i++){
                Node n =listOfNodes.item(i);
                System.out.println("Name: "  +n.getNodeName());
                System.out.println("Type: "  +n.getNodeType());
                NamedNodeMap nodeMap = n.getAttributes();
                for(int j = 0 ; j<nodeMap.getLength();j++){
                    System.out.println("\tNodeName: "  +nodeMap.item(j).getNodeName());                   
                    System.out.println("\tNodeType: "  +nodeMap.item(j).getNodeType());
                }
            }
            int totalNodes = listOfNodes.getLength();
            System.out.println("Total no of node : " + totalNodes);
        } catch (SAXException ex) {
        //some unnecessary output
    }

---

The code above produces this output

Code:

---

Root element of the doc is ns0:ArchiveJob
Name: ns0:ArchiveJob
Type: 1
        NodeName: jobname
        NodeType: 2
        NodeName: xmlns:ns0
        NodeType: 2
        NodeName: xmlns:xsi
        NodeType: 2
        NodeName: xsi:schemaLocation
        NodeType: 2
Name: ns0:age
Type: 1
        NodeName: value
        NodeType: 2
Total no of node : 2

---

The NodeTypes you can see in in Output (1,2) are referring to Element Nodes (1) and Attribute Nodes (2). I understand this and it sounds logical, but unfortunately this is not what I want to have!!! Is there something to get the type (self definied) of an element tag???

Thx for suggestions
