add a xml document

[Jack]

I would like to know what are JAVA frameworks for update and query an XML document?

thanks.

[Ed]

JDOM, any XSLT processor like Xalan.

What might be more interesting is what you want to do. If you really want to create an XML document from another XML document with selections and filtering, I would go with an XSLT processor. Inserting nodes is probably better done with something like JDOM.

If you want to add nodes in an object-oriented way JDOM is the best. Sure the whole document is in memory but what do you expect? Object = something in memory ;-)

In case you need some java binding, objects that are mapped to xml and back, try castor or jaxb. But this is memory expensive too.
