Attached is a small example of importing nodes into new document
from other documents.

All,

First, thanks to Christopher and Paul for the prompt responses to my
request.

I tried using the XMLSerializer technique mentioned by Paul and shown in the
DOMGenerate example sent by Christopher.  I'm getting closer, but I'm still
not there yet.  I am getting a "Wrong document" error (WRONG_DOCUMENT_ERR)
on appendChild because the child node that I am appending to my new document
comes from a different document.

Looking at the DOMGenerate example a little closer, I see that all of the
nodes that are placed into the new document via appendChild are always new
nodes, not nodes from another document.

Any suggestion on how to get around this latest twist?  Is there something I
can do when creating the new DocumentImpl, perhaps telling the constructor
to create a new document based on an existing one?  Maybe I don't need to
create a document at all?  Is there a way to serialize just a node instead
of an entire document?  I see there is a serializeNode() method, but it
protected, so I don't think I can use it.

Again, any help would be greatly appreciated!

Here's my code (mostly stolen from DOMGenerate).  "divDetailedDescription"
is the node I am trying to print to a file.

    Document outDoc= new DocumentImpl();
    Element root = outDoc.createElement( "Section2" );     // Create Root
Element
    root.appendChild( divDetailedDescription );            // Attach Element
as a child of root

    outDoc.appendChild( root );                            // Add Root to
Document

    OutputFormat    format  = new OutputFormat( outDoc );   //Serialize DOM
    XMLSerializer    serial = new XMLSerializer( outStream, format );
    serial.asDOMSerializer();                            // As a DOM
Serializer

    serial.serialize( outDoc.getDocumentElement() );

Thanks,
Michael

Subject: Parsing a document and writing out a specfic node to a new file


All,

I am in desperate need of some sample code that writes a node to a file.
More specifically, I am provided with an XHTML file as input.  I need to
scan/parse the document for a specific node.  Once found, I need to create a
second XHTML file which contains just this node (and all of its child
nodes).

I think I have the first part down.  I parse the input file as a Document
and use various methods like getDocumentElement(), getLastChild(), and
getChildNodes() to get to the specific node I am looking for.  However, now
that I have a node, I don't know how to create a file and output all of the
node's contents into the file.

Can please someone suggest some classes and methods to look into?  Even
better would be some sample code!

Sincerely,
Michael S. Goldberg
