Kapil, it may help if you read http://xmlbeans.apache.org/docs/2.0.0/guide/conJavaTypesGeneratedFromUserDerived.html. First of all, it bears repeating that an XmlObject represents an instance of an XML Schema type, i.e., it represents the *contents* of an xml element or attribute, not the element or attribute itself. Secondly, XMLBeans generates a Document interface for global elements in a schema, which could potentially be the root element of some xml document. There is no Document interface generated for elements that are not global, so in general, you cannot expect there to be one for elem1 or elem2 in your example. The Document represents an xml document containing the global element, *not* the element. Working with XmlCursor, on the other hand, is a different paradigm where you're working at a low level, directly navigating the xml itself. So, you will see things such as the QName of the elements and so on that you encounter.

I am now aware of the things you pointed out. What I am looking for is some way to get XmlObject that represents the element and not the type. This might map to document type XmlObject, am I correct? So the the problem is reduced to: Once I have selected the XmlObject representing the contents of a child element (by calling cursor.getObject()), how do I create an untyped document XmlObject based on the knowledge of the cursor name. To elaborate on what I am trying to do, consider the XML whose root element is rootElem and it has two children elem1 and elem2: rootElem -> elem1 -> child1 -> child2 -> elem2 After using cursor.getObject() for firstChild, I get an XmlObject which has xmlText of the child-contents of "elem1" and the cursor name is "elem1". If I pass this object to another method as XmlObject it will need to recreate its cursor to determine its name. Is there a way to create a document type XmlObject which has the root element "elem1" and it shows up in the xmlText() along with the previously selected contents? If I call another method with this document-type XmlObject, the code in this different method will still need to create a cursor to determine its qname, but now I can at least string compare the contents with another XMLObject with was parsed from a different source as a document-type. regards kapil Cezar Andrei-3 wrote: > > Kapil, > > You don't need to create a new cursor, if the item your cursor points to > has a name (i.e. element/attribute/pi) just call getName() on it.
