Reg: XML Dom parsers and updators.

[premkumar srinivasan <pr...@gmail.com>]

Hi,

Is there any open source based on XML, that allows us to do the following:
- Parse XML into a DOM Tree.
- Retrieve the XML data using XPATH queries.
- Update the DOM Tree, based on the update-type. It might be DOM node
updation, or addition of a new DOM node sets.

It's something like making XML file, a database, and use "SQL" sort of
queries to update/retrieve data.

Your suggestions would be really helpful for me.

Thanks,
--Prem.
