AppendChild - not working

Question

I cannot build an xml document as a combination of nodes.
pls tell me if i am doing something wrong here.
PROCEDURE BUILD_XML IS
doc dbms_xmldom.DOMDocument;
RootNode dbms_xmldom.DOMNode;
node dbms_xmldom.DOMNode;
docelem dbms_xmldom.DOMElement;
buf varchar2(2000);
BEGIN
doc := dbms_xmldom.newDOMDocument('<PARAMETERS></PARAMETERS>');
docelem := dbms_xmldom.getDocumentElement( doc );
RootNode := dbms_xmldom.makeNode(docelem);
node := dbms_xmldom.makeNode(dbms_xmldom.newDOMDocument('<abc>12345</abc>'));
node := dbms_xmldom.appendChild(RootNode,node);
dbms_xmldom.writetobuffer(node, buf);
dbms_output.put_line('Node Buffer : ' || buf);
dbms_xmldom.writetobuffer(RootNode, buf);
dbms_output.put_line('RootNode Buffer : ' || buf);
END;
The results are :
Node Buffer : <abc>12345</abc>
RootNode Buffer : <PARAMETERS/>
and i want them to be :
Node Buffer : <abc>12345</abc>
RootNode Buffer : <PARAMETERS><abc>12345</abc></PARAMETERS>
I am creating a document using newDOMDocument.
Then I create a new node, also as DOMDocument using newDOMDocument.
Then i try to append the second to the first as a child.
No Error here, but i cannot see the results.
Maybe my approach is totally wrong and i need something else..
Help is needed.
Thanks

Answer 1

i'm having the same problem :(
i've come across other example code that uses appendChild but i'm not sure if it works in that either
