How to get element names from schema

[Nathan Russell]

Hi,
I hope I'm posting in the right section, and I hope someone can point me in the right direction with this.

I have the following XML schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="WORKREQUEST">
<xs:annotation>
<xs:documentation>Inbound Work Request</xs:documentation>
</xs:annotation>
<xs:complexType>
<xs:sequence maxOccurs="unbounded">
<xs:element name="ISSUE">
<xs:complexType>
<xs:complexContent>
<xs:extension base="ctISSUE"/>
</xs:complexContent>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="VERSION" type="xs:decimal" use="required" fixed="1.0"/>
</xs:complexType>
</xs:element>
<xs:simpleType name="stDATE">
<xs:annotation>
<xs:documentation>Date type</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:dateTime">
<xs:whiteSpace value="collapse"/>
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="stENUMEQUIP">
<xs:annotation>
<xs:documentation>ID Equipment enumeration at this Location/Failure</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:string">
<xs:whiteSpace value="collapse"/>
<xs:maxLength value="2"/>
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="stIVRCODE">
<xs:annotation>
<xs:documentation>IVR Code Form</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:string">
<xs:length value="7"/>
<xs:whiteSpace value="collapse"/>
<xs:pattern value="[0-9]{7}"/>
</xs:restriction>
</xs:simpleType>
<xs:complexType name="ctISSUE">
<xs:annotation>
<xs:documentation>The details of the Issue</xs:documentation>
</xs:annotation>
<xs:sequence>
<xs:element name="COUNTRY" type="stCOUNTRY"/>
<xs:element name="ISSUEDATETIME" type="stDATE"/>
<xs:element name="LOCATION" type="stMAXID"/>
<xs:element name="IVRCODE" type="stIVRCODE"/>
<xs:element name="ENUMEQUIP" type="stENUMEQUIP"/>
</xs:sequence>
<xs:attribute name="EXTREF" type="stMAXID" use="required"/>
</xs:complexType>
<xs:simpleType name="stMAXID">
<xs:annotation>
<xs:documentation>Maximo ID Reference</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:string">
<xs:maxLength value="50"/>
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="stCOUNTRY">
<xs:annotation>
<xs:documentation>The country code for the source data</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:string">
<xs:enumeration value="DK"/>
<xs:enumeration value="BE"/>
<xs:enumeration value="LU"/>
<xs:enumeration value="NL"/>
<xs:enumeration value="CZ"/>
<xs:enumeration value="GB"/>
<xs:enumeration value="PL"/>
<xs:enumeration value="SK"/>
<xs:enumeration value="AT"/>
<xs:enumeration value="CH"/>
<xs:enumeration value="NO"/>
<xs:enumeration value="FI"/>
<xs:enumeration value="SE"/>
<xs:enumeration value="IT"/>
<xs:enumeration value="GR"/>
<xs:enumeration value="DE"/>
</xs:restriction>
</xs:simpleType>
</xs:schema>

and I have loaded this into an XMLSchema object from the Oracle XDK.
I can use this to validate DOMParser objects also from the Oracle XDK, and all is working well.

What I would like to do now though is be able to iterate through / enumerate the element names in the schema. So, from the above schema, I would like to produce a list of COUNTRY, ISSUEDATETIME, LOCATION, IVRCODE, and ENUMEQUIP
Can I work out how to do this ? Can I 'eck !

Any help with this would be very much appreciated !

TIA
Nathan
