XML and multiple namespaces

user13117585Aug 31 2016 — edited Sep 15 2016

Hello,

I have a quick question about XMLType and how to extract values from it... I have one with many namespaces like this one:

WITH T AS (

   SELECT

'

   <project xmlns="http://www.test.com/xid/v2">

     <Node>NodeValue</Node>

     <Content>

       <Document:Document xmlns:Document="http://other.domain.be/prj/types/prj/file/1" xmlns="http://other.domain.be/prj/types/prj/file/1">

         <Details>

           <Id type="Local">123456</Id>

           <Id type="Remote">654321</Id>

         </Details>

       </Document:Document>

     </Content>

   </project>

' x

FROM dual 

SELECT ExtractValue(XMLType(x), '/project/Node', 'xmlns="http://www.test.com/xid/v2"'),

       ExtractValue(XMLType(x), '/project/Content/Document/Details/Id[@type="Local"]', 'xmlns="http://www.test.com/xid/v2"')

  FROM t;

And when I try to extract Local Id of a document, it always returns null. Any idea why? I'm using Oracle 11.2;

Thank you for your help.
