Select XML Element

Question

Hi,
I have loaded XML in the local database table remotely in the URL (http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml)
CREATE TABLE url_tab
  URL_NAME VARCHAR2(100),
  URL      SYS.URIType
INSERT INTO url_tab VALUES
('This is a test URL',
sys.UriFactory.getUri('http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml')
CREATE TABLE xml_data_tab ( xml_data xmltype );
insert into xml_data_tab select sys.xmltype.createXML(u.url.getClob()) from url_tab u;
I am able to read the BANK NAME use the below query and the output of the query is  "  European Central Bank "
select  *  from
XMLTable(XMLNamespaces('http://www.gesmes.org/xml/2002-08-01' as "gesmes"),
                       '/gesmes:Envelope'
                     PASSING  (select * from xml_data_tab)
                     columns
                    Bank_name varchar2(100)   path '/gesmes:Envelope/gesmes:Sender/gesmes:name'
                    ) xt;
Can you please help me out with the SQL or PL/SQL code to read the DATE, Currency Code and the Conversion Rate available in the XML.
Thank you.

I don't know what kind of tool you are using. It looks it can not handle the opague datatype XMLType. Make an attempt via the following...
select  x1.cubexml.getCLOBVal()  as result
from XMLTable(XMLNamespaces('http://www.gesmes.org/xml/2002-08-01' as "gesmes"),   
'/gesmes:Envelope' 
                PASSING  (select * from xml_data_tab) 
                columns
                  cube_date  varchar2(4000)  path 'Cube/Cube/@time', 
                  cubexml xmltype 'Cube/Cube' 
                ) x1  ;
or
select  XMLSERIALIZE( CONTENT x1.cubexml  as CLOB indent size=1) as result
from XMLTable(XMLNamespaces('http://www.gesmes.org/xml/2002-08-01' as "gesmes"),   
'/gesmes:Envelope' 
                PASSING  (select * from xml_data_tab) 
                columns
                  cube_date  varchar2(4000)  path 'Cube/Cube/@time', 
                  cubexml xmltype 'Cube/Cube' 
                ) x1  ;
