"no raws selected" message for structured storage to xml doc

Question

hi every one , wish really u can help with this problem
Well …
One stage of my project is to store an xml file into a table of XMLType column in structured way (using the schema)
So that’s what I did:
1.     I copied the schema file into this folder http://localhost:8080/public/
2.     Then I register the schema
SQL> ALTER SESSION SET EVENTS='31098 trace name context forever';
Session altered.
1 begin
2 dbms_xmlschema.registeruri(
3 'http://localhost:8080/public/auction.xsd',
4 '/public/auction.xsd',
5 local=>true, gentypes=>true, genbean=>false, gentables=>false);
6* end;
SQL> r
1 begin
2 dbms_xmlschema.registeruri(
3 'http://localhost:8080/public/auction.xsd',
4 '/public/auction.xsd',
5 local=>true, gentypes=>true, genbean=>false, gentables=>false);
6* end;
PL/SQL procedure successfully completed.
3.     after that I create the table as it mentioned below
SQL> create table struc_100kb( xmldoc sys.xmltype)
2 xmltype column xmldoc store as object relational
3 xmlschema "http://localhost:8080/public/auction.xsd"
4 element "site";
Table created.
SQL>SQL> describe struc_100kb
Name Null? Type
XMLDOC SYS.XMLTYPE(XMLSchema "http:
//localhost:8080/public/auct
ion.xsd" Element "site") STO
RAGE Object-relational TYPE
"site171_T"
4.     then I used he sqlldr to load the xml document , and that what included in the control file
load data
infile *
replace
into table struc_100kb
fields terminated by ','
fname filler char(40),
xmldoc lobfile(fname) terminated by EOF
begindata
c:\amal\xmldoc\xmldoc_used\doc100kb.xml
C:\oracle\product\10.1.0\db_1\BIN>sqlldr scott/**** control=c:\amal\work.ctl
But after that when I run any query such as this
select e.xmldoc.extract( 'site/people/person[@id="person12"]/name/text()') from struc_100kb e
I got a message no rows selected
So whats my problem??
