Exception: DeferredTextImpl

[Seth Ladd <sh...@osfmail.isc.rit.edu>]

Hello,

I'm sorry if this has been mentioned before on the mailing list.  I
tried to look through the archives, but I didn't see this.

I am trying to use the latest Xerces-J parser, but I get an exception
when I try to access the first child from the root.

I get a java.lang.ClassCastException:
org.apache.xerces.dom.DeferredTextImpl exception thrown when I try to
execute the line:

child = (Element)trueroot.getFirstChild();

I'm not sure what to do, since I'm not sure what the exception message
is telling me.  I am using the IBM JDK 1.1.8 JDK on Linux 2.2.13.  The
Xerces-J parser is the latest from CVS.

Here is a code snipet:

DOMParser parser = new DOMParser();
parser.parse(filename);
Document doc = parser.getDocument();
Element trueroot = (Element)doc.getDocumentElement();
Element child = (Element)trueroot.getFirstChild();

Any hints or ideas would be greatly appreciated.

Thanks very much,
Seth

Thanks so much!  I think I looked everywhere else for the solution to this
but right here. :(  There was whitespace as the firstChild(), which is
where I was getting confused.

Thanks,
Seth

Seth,

The first child of the result of  getDocumentElement is not guaranteed
to be an Element.    The ClassCastException is telling you that you are
trying to cast a Text Node into an ElementNode -- which doesn't work.
