the domparser.getDocument() method returns the
a node that is really a document node. The same thing happens when
getChildNodes() is called instead of getFirstChild().
The problem is that this same code works for other
documents, but not this one. I was hoping other people have had this
problem.

Could it be the domparser.getDocument() (probably returns a Document
and not a Node). There are methods that return Node type or use the methods
that return NodeList- see api doc. Just a guess, I don't work with
DOM.

I get the following exception when trying to
iterate over a documents child elements. It only happens the first
time, but I have moved the calling code so it only happens once and messes
up the initialization of my program. Here is the offending
code
...
domparser.parse(filename);
Node documentNode =
domparser.getDocument();
exception-> Node
documentChildNode = documentNode.getFirstChild();
and the accompanying stack trace:
java.lang.ClassCastException:

Does anyone know how I can access a documents
child elements without causing this exception? Is there something I
need to call first?
Thanks in advance
