The following query does work in Oracle 9.2.0.4 (and 9.2.0.5), but does not work in Oracle 10.1.0.3 (Linux)

SELECT *
FROM MEDIA_CONTENT
WHERE EXISTSNODE
(MCON_XML,
'/rdf:RDF/rdf:Description[ora:contains(dc:title,"Whale")>0]',
'xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:ora="http://xmlns.oracle.com/xdb"')

The error message

ORA-29913: error in executing contains callout
ORA-15198: operation [contains with non-leaf node] is not yet available

indicates, that this feature is not yet available in Oracle 10.1.0.3

Does anybody know, when this feature is available in Oracle 10, too ? Already in 10.1.0.4 ? Or in Oracle 10g Release 2 ?

Thanks,

Ulf
