XSD with xs:any and then querying in the xs:any part

Question

Hi,
I'm having troubles querying for elements in an xs:any part of a schema. Trouble as in: can't get to the data anymore using simple xquery/xpath expressions.
I have a XSD with an xs:any element:
(the actual XSD is bigger, this is a smaller, test version)
<?xml version="1.0" encoding="windows-1252"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           targetNamespace="http://localhost/anydata.xsd"
           xmlns:xdb="http://xmlns.oracle.com/xdb"
           xmlns="http://localhost/anydata.xsd"
           elementFormDefault="qualified"
           attributeFormDefault="unqualified"
           version="1.0">
    <xs:element name="anydata" type="anydataType" xdb:defaultTable="ANYDATA"/>
    <xs:complexType name="anydataType">
        <xs:sequence>
            <xs:any namespace="##any" minOccurs="0" maxOccurs="unbounded" processContents="lax" />
        </xs:sequence>
        <xs:attribute name="refId" type="xs:string" use="required" />
    </xs:complexType>
</xs:schema>I register the xsd and create the default table (following binary xml) with the following code (after uploading the anydata.XSD using ftp to /public/tmp):
set serveroutput on
VAR schemaURL VARCHAR2(256)
VAR schemaPath VARCHAR2(256)
BEGIN
   :schemaURL := 'http://localhost/anydata.xsd';
   :schemaPath := '/public/tmp/anydata.xsd';
END;
-- Delete schema if already there, delete with cascade
BEGIN
  DBMS_XMLSchema.deleteSchema(
    schemaurl=>:schemaURL,
    delete_option=>DBMS_XMLSchema.Delete_Cascade_Force);
END;
BEGIN 
    dbms_xmlschema.registerSchema(
    SCHEMAURL  => 'http://localhost/anydata.xsd',
    SCHEMADOC  => xdbURIType('/public/tmp/anydata.xsd').getClob(),
    LOCAL      => TRUE,
    GENTYPES   => FALSE,
    GENBEAN    => FALSE,
    GENTABLES  => TRUE,
    FORCE      => FALSE,
    OPTIONS    => DBMS_XMLSCHEMA.REGISTER_BINARYXML,
    OWNER      => USER);
END;
/Inserting some data with an <a>a</a> element:
INSERT INTO anydata VALUES (XMLType('<?xml version="1.0" encoding="ISO-8859-1"?><anydata xmlns="http://localhost/anydata.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://localhost/anydata.xsd http://localhost/anydata.xsd" refId="a12ab"><a>a</a></anydata>'));No problems here:
SQL> select * from anydata;
SYS_NC_ROWINFO$
<?xml version="1.0" encoding="ISO-8859-1"?>
<anydata xmlns="http://localhost/anydata.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://local
host/anydata.xsd http://localhost/anydata.xsd" refId="a12ab">
  <a>a</a>
</anydata>Select the refId is no problem:
SQL> SELECT * FROM XMLTable('
  2  declare default element namespace "http://localhost/anydata.xsd"; (: :)
  3  for $f in ora:view("anydata")
  4      return $f/anydata/@refId'
  5  ) xtab;
COLUMN_VALUE
a12abBut getting the <a> value... seems to be impossible, whatever I try:
SQL> SELECT * FROM XMLTable('
  2  declare default element namespace "http://localhost/anydata.xsd"; (: :)
  3  for $f in ora:view("anydata")
  4      return $f/anydata/a'
  5  ) xtab;
SELECT * FROM XMLTable('
ERROR at line 1:
ORA-19276: XPST0005 - XPath step specifies an invalid element/attribute name: (a ='http://localhost/anydata.xsd')So probably something to do with <a> not being part of the schema. I've also tried the following, to see if I can only apply the namespace to the appropriate elements:
SQL> SELECT * FROM XMLTable('
  2  declare namespace ad="http://localhost/anydata.xsd"; (: :)
  3  for $f in ora:view("anydata")
  4      return $f/ad:anydata/a'
  5  ) xtab;
SELECT * FROM XMLTable('
ERROR at line 1:
ORA-19276: XPST0005 - XPath step specifies an invalid element/attribute name: (a)Doesn't help either.
Anyone ever seen this and solved it?

Hi,
I've patch my system with the following patch (id 7009297):
ORACLE 11G 11.1.0.6 PATCH 3 BUG FOR WINDOWS X-64 BIT AMD
And the result
SQL> SELECT * FROM XMLTable('
  2    declare namespace ad="http://localhost/anydata.xsd"; (: :)
  3    for $f in ora:view("anydata")
  4        return $f/ad:anydata/ad:a'
  5  ) xtab;
<a xmlns="http://localhost/anydata.xsd">a</a>So, it works. Thanks for the help!
