Thanks Cezar.
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.
