Re: Changing the class of element, node, etc created by a parser

I am having trouble appending a document fragment from one
document to a different document. In the following code, I
am trying to append all the children of document r to document
s. It fails with

WRONG_DOCUMENT_ERR: A node is used in a different document than the one 
that created it.
Here is the code:

Range rdf = ((DocumentImpl)r).createRange();
rdf.setStartBefore(r.getLastChild());
rdf.setEndAfter(r.getLastChild());
DocumentFragment df= rdf.extractContents(); // doesn't this allow the 
document fragment
s.getFirstChild().appendChild(df); // to be appended to a different 
document?
Your assistance would be greatly appreciated.

Incidentally, I can disable the error by modifying the code in 
CoreDocumentImpl.java, but
I would prefer to use the library in the manner which was intended.
