Xmltable returning no rows

Question

I have the following XML
<?xml version = '1.0' encoding = 'UTF-8'?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:sawsoap="urn://oracle.bi.webservices/v6">
   <soap:Body>
      <sawsoap:getGroupsResult>
         <sawsoap:account xsi:type="sawsoap:Account">
            <sawsoap:name>Presentation Server Administrators</sawsoap:name>
            <sawsoap:accountType>1</sawsoap:accountType>
            <sawsoap:guid>bipse53c4188a730640cc6c0a242</sawsoap:guid>
         </sawsoap:account>
         <sawsoap:account xsi:type="sawsoap:Account">
            <sawsoap:name>AuthenticatedUser</sawsoap:name>
            <sawsoap:accountType>4</sawsoap:accountType>
            <sawsoap:guid>AuthenticatedUser</sawsoap:guid>
         </sawsoap:account>
         <sawsoap:account xsi:type="sawsoap:Account">
            <sawsoap:name>BIConsumer</sawsoap:name>
            <sawsoap:accountType>4</sawsoap:accountType>
            <sawsoap:guid>BIConsumer</sawsoap:guid>
         </sawsoap:account>
      </sawsoap:getGroupsResult>
   </soap:Body>
</soap:Envelope>I am trying to generate the list of account types, which in this case would just be
Presentation Server Administrators
AuthenticatedUser
BIConsumer
I am using the following SQL statement in my attempt, but it is returning zero rows.
select x.*
from tony, xmltable ('/account'
passing extract(x,'//sawsoap:getGroupsResult','xmlns:sawsoap="urn://oracle.bi.webservices/v6"')
columns
group_name varchar2(255) path '/name'
) x;I have tried different combinations of XPaths, including the sawsoap:account and sawsoap:name,but other continue to return no records. I have the sense that I am close and would appreciate a second set of eyes that could point out the mistake.

Welcome to the forums. When posting, always include your version as shown by
select * from v$version
It makes a difference. For your issue, you are mixing some pre 10.2 syntax (extract) with 10.2 and later syntax (XMLTable).
What you are looking for is something like
WITH tony AS
(SELECT XMLTYPE('<?xml version = ''1.0'' encoding = ''UTF-8''?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:sawsoap="urn://oracle.bi.webservices/v6">
   <soap:Body>
      <sawsoap:getGroupsResult>
         <sawsoap:account xsi:type="sawsoap:Account">
            <sawsoap:name>Presentation Server Administrators</sawsoap:name>
            <sawsoap:accountType>1</sawsoap:accountType>
            <sawsoap:guid>bipse53c4188a730640cc6c0a242</sawsoap:guid>
         </sawsoap:account>
         <sawsoap:account xsi:type="sawsoap:Account">
            <sawsoap:name>AuthenticatedUser</sawsoap:name>
            <sawsoap:accountType>4</sawsoap:accountType>
            <sawsoap:guid>AuthenticatedUser</sawsoap:guid>
         </sawsoap:account>
         <sawsoap:account xsi:type="sawsoap:Account">
            <sawsoap:name>BIConsumer</sawsoap:name>
            <sawsoap:accountType>4</sawsoap:accountType>
            <sawsoap:guid>BIConsumer</sawsoap:guid>
         </sawsoap:account>
      </sawsoap:getGroupsResult>
   </soap:Body>
</soap:Envelope>') x
   FROM dual)
-- The above WITH simulates your table.  You only care about the below  
SELECT x.*
  FROM tony,
       XMLTable(XMLNamespaces('http://schemas.xmlsoap.org/soap/envelope/' AS "soap",
                              'urn://oracle.bi.webservices/v6' AS "sawsoap"),
                '/soap:Envelope/soap:Body/sawsoap:getGroupsResult/sawsoap:account'
                PASSING tony.x
                COLUMNS
                group_name   VARCHAR2(40) PATH 'sawsoap:name'
               ) x;
GROUP_NAME
Presentation Server Administrators
AuthenticatedUser
BIConsumer
