Of interest from the XML-dev list. DW
You can get XMLBeans from http://xmlbeans.apache.org/ The XmlCursor currently loads the entire document you're working on in memory and you can walk/inspect it like DOM but with less overhead. We're currently looking into a streaming version of XmlCursor. Stay tuned. -- Kevin Krouse BEA Systems -----Original Message----- From: Gregory Murphy [mailto:Gregory.Murphy@eng.sun.com] Sent: Friday, September 24, 2004 10:29 AM To: David Byrden Cc: xml-dev@lists.xml.org Subject: Re: [xml-dev] Editing huge files; recommended Java parsers?

You might want to look at the XML Cursor API provided by BEA XMLBeans.
It
allows you to walk through a document, token by token, and as needed
create
DOM-like objects of fragments. You can learn more from the on-line
documenatation:
