Problem trying to get at /Resource/Contents xml stuff

Question

Hi there,
I have created the following:
DECLARE
retb boolean;
BEGIN
retb := dbms_xdb.createFolder('/public/mydocs');
commit;
END;
declare
bret boolean;
begin
bret := dbms_xdb.createresource('/public/mydocs/emp_maggie.xml','<name>maggie</name>');
commit;
end;
My problem is this: I would like to get the emp_maggie.xml
details back out of the resource but I am unable to figure out
a way to do this. I can see that there is something in the
/Resource/Contents tag by doing the following:
SELECT p.res.GETCLOBVAL() FROM path_view p WHERE p.path = '/public/mydocs/emp_maggie.xml';
which results in:
<Resource xmlns="http://xmlns.oracle.com/xdb/XDBResource.xsd" Hidden="false" Inv
alid="false" Container="false" CustomRslv="false" VersionHistory="false">

</Contents>
</Resource>
I have a tried a variety of commands including:
select p.res.extract('/Resource/Contents/*').getStringVal() from resource_view p where equals_path(res, '/public/mydocs/emp_maggie.xml') > 0;
select extract(res, '/Resource/Contents/*').getStringVal() from resource_view p where equals_path(res, '/public/mydocs/emp_maggie.xml') > 0;
select extract(res, '/Resource/Contents/*') from resource_view p where equals_path(res, '/public/mydocs/emp_maggie.xml') > 0;
all of which result in "1 row selected" but without showing any details of the xml
document of interest.
Does anybody know of a solution?
Cheers,
Maggie

Mark,
thanks for the help.
This now seems to work, so long as I put an initial "/" before the public path:
select xdburitype('/public/mydocs/emp_maggie.xml').getXML() from dual;
Would still be great to know how the extract() and get_contents() methods are meant
to work as detailed in table 13.3 of the Oracle9i XML database developers guide - Oracle XML DB Release 2.
Cheers,
Maggie
