The serialization interface you are using will tie your app to Crimson. Another way is to use javax.xml.transform, but that would conflict w/ keeping your app small. Another option is to require running on JDK 1.4 which includes JAXP within it so you would not need to bundle anything w/ your app. Also see the JAXP FAQ at http://xml.apache.org/~edwingo/jaxp-faq.html#output for more info. That page also has pointers to other non-Apache parsers. > > I can serialize a Document fine, but I haven't figured out how to > serialize any other type of DOM Node.

If you or anyone else wants to figure it out, I'd start looking at the code in org/apache/crimson/tree/ElementNode and ElementNode2.java. -Edwin --------------------------------------------------------------------- In case of troubles, e-mail: [EMAIL PROTECTED] To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
