XML queries (EXISTSNODE, CONTAINS) giving inconsitance results

Question

Hi,
I am querying data from a table that has xmltype datatype and getting inconsistant results with two different approaches. I would like to have the top 500 records for a "REGION". My first query uses CONTAINS with "HASPTH" and the second query uses the condition EXISTSNODE with XPATH value. The table has both the indexes CTXSYS.CTXXPATH and CTXSYS.CONTEXT
Can somebody help me to understand why I am getting inconsistant results?
The sample xmltype data would be like:
<REC>
<CUSTID>14590</CUSTID>
<LNAME>McDonald</LNAME>
<FNAME>Warren</FNAME>
<REGION>Orlando</REGION>
</REC>
Here my 1st query with CONTAINS and "HASPATH"
SELECT /*+ FIRST_ROWS */ a.xmldata.CUSTID TAG1, a.xmldata.LNAME TAG2,
a.xmldata.FNAME TAG3
FROM CR_XML a WHERE
CONTAINS(sys_nc_rowinfo$,'(haspath (//REGION = "Orlando)"))',1)>0 and
rownum <501 order by 1
2nd query with EXISTSNODE:
SELECT /*+ FIRST_ROWS */ a.xmldata.CUSTID TAG1, a.xmldata.LNAME TAG2,
a.xmldata.FNAME TAG3
FROM CR_XML a WHERE
EXISTSNODE (sys_nc_rowinfo$,'/REC[REGION="Orlando"]')=1 and
rownum <501 order by 1
Thanks,
Ravi

Thanks. I had seen the note that the problem didn't happen if he didn't use a DataSource connection, but had taken that to be just more data about the problem, rather than his solution. I am surprised that you would have to use a deprecated class (or am I wrong about that?) in order to use XSU with object types. Was this issue perhaps really a version compatibility issue among XSU,JDBC driver and JDK? I'd like to find a way to use XSU to produce XML from an object view using a data source connection, but am stuck currently at the same spot the original poster was. Can you help with that,please?
