Hi.

You may want to take a look at the XML:DB API project at
http://www.xmldb.org/xapi/index.html. Quoted from the project page:

The XML:DB API is designed to enable a common access mechanism to XML
databases. The API enables the construction of applications to store,
retrieve, modify and query data that is stored in an XML database.
These facilities are intended to enable the construction of applications
for any XML database that claims conformance with the XML:DB API. The
API can be considered generally equivalent to technologies such as ODBC,
JDBC or Perl DBI. 


The API comes with a filesystem based reference implementation which
works pretty well. Other implementations are available (Java: dbXML)
or underway (Java: Ozone, Python: 4Suite)


Regards,
Lars
