That doesnt work as getElements() returns an XmlObjectTable and this doesn't have an interator() method however it does have getNames() and getValues() which return iterators so I've tried:
XmlSchemaElement e = (XmlSchemaElement)schema.getElements().getNames().next(); error message: java.lang.ClassCastException: javax.xml.namespace.QName cannot be cast to org.apache.ws.commons.schema.XmlSchemaElement I've also tried: XmlSchemaElement e = (XmlSchemaElement)schema.getElements().getValues().next(); This works so I now have an XmlSchemaElement object called e. And from this you say to call getSchemaType to work my way down so I've tried this however I don't see how to return the names of the elements in the complex type ie. to, from, heading, body. Thanks for your help with this, can you explain further please?
