Insert xml Node into a CLOB column with namespace in Oracle

I have next below xml value in CLOB column in Oracle 11g.

<Energy xmlns="http://euroconsumers.org/notifications/2009/01/notification">     
    <WEBSITE>WWW.VERLAAG.BE</WEBSITE>
    <CUSTOMERID>xxxxxx</CUSTOMERID>
    <Gender>M</Gender>
    <Telephone>0000000000</Telephone>
</Energy>

I want to add a new node called: Language

to look like this:

<Energy xmlns="http://euroconsumers.org/notifications/2009/01/notification">     
    <WEBSITE>WWW.VERLAAG.BE</WEBSITE>
    <CUSTOMERID>xxxxxx</CUSTOMERID>
    <Gender>M</Gender>
    <Telephone>0000000000</Telephone>
    <Language></Language>
</Energy>

I've used next below sentence:

update tmp_tab_noemail_test_aankoop p1
set p1.sce_msg = insertchildxml(p1.sce_msg, '/Energy', 'Language',
                 xmltype('<Language><Language/>'),
                 'xmlns="http://euroconsumers.org/notifications/2009/01/notification')
.getclobval();

And also this one:

update tmp_tab_noemail_test_aankoop p1
set p1.sce_msg = APPENDCHILDXML(p1.sce_msg,
                 '/Energy',
                 XMLType('<Language><Language/>'),
                 'xmlns="http://euroconsumers.org/notifications/2009/01/notification')
.getclobval()

But any of these functions are working.

Any idea?

In both of your statements you are not converting your initial CLOB to XMLType, and your closing tag for the new node is malformed - you have <Language/> instead of </Language>. Either provide opening and closing tags, or a single self-closing one, not a mix of both. You're also missing the closing double-quote in your namespace.

These both work:

update tmp_tab_noemail_test_aankoop p1
set p1.sce_msg = insertchildxml(XMLType(p1.sce_msg), '/Energy', 'Language',
  XMLType('<Language></Language>'),
  'xmlns="http://euroconsumers.org/notifications/2009/01/notification"').getclobval();

Or:

update tmp_tab_noemail_test_aankoop p1
set p1.sce_msg = APPENDCHILDXML(XMLType(p1.sce_msg), '/Energy',
  XMLType('<Language></Language>'),
  'xmlns="http://euroconsumers.org/notifications/2009/01/notification"').getclobval();

The latter looks a little better as the new tag appears as

<Language/>

rather than

<Language xmlns=""/>

You can preserve the namespace with insertchild but then it appears explicitly in the new node even though it matches the top-level Energy namespace; which doesn't matter functionally but looks a bit odd.
