It is supported in PostgreSQL (see http://developer.postgresql.org/cvsweb.cgi/pgsql/contrib/xml2/README.xml2) but I do not know about the performance (I don't know if there is XML-oriented indexation). ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
