[jdom-interest] Question from a newbie - How to make a copy of a Document

[Brad Morgan]

I have a Java program that massages the XML index for a JavaHelp helpset to
produce an XML glossary.  Currently this program processes the files as
ASCII text.  I'd like to convert the program to process the documents as XML
using JDOM.

Both documents use the same DTD.  I have a list (produced by the authoring
tool) which I have parsed that provides me with a type for each indexitem
element.  When this type is glossary, I want to remove the indexitem from
the index XML file and add it to the glossary XML file.
The rest of the XML document should be identical.

One approach would be to use:

            SAXBuilder builder = new SAXBuilder();
		SAXBuilder builder2 = new SAXBuilder();
            // Create the document
            Document doc = builder.build(new File(filename));
	      Document doc2 = builder2.build(new File(filename));

and then walk both lists removing indexitems when type == glossary or type
!= glossary as appropriate, but in looking at the Javadoc documentation, I
see a clone() method with the comment "This will return a deep clone of this
Document".  What does this mean and is this
useful to me?  If so, how do I use it because:

            SAXBuilder builder = new SAXBuilder();
            // Create the document
            Document doc = builder.build(new File(filename));
	      Document doc2 = doc.clone();

doesn't compile.  Also scrutinized my copy of "Java and XML" and didn't find
anything.
