XML Namespace in PL/SQL

Question

Hi to all,
I have a problem, when i build a XML document in my PL/SQL, using xmldom class, i want to set xmlns only in root node.
This is my code:
doc xmldom.DOMDocument;
main_node xmldom.DOMNode;
root_node xmldom.DOMNode;
root_elmt xmldom.DOMElement;
root_elmt_attributato xmldom.DOMElement;
BEGIN
doc := xmldom.newDOMDocument;
main_node := xmldom.makeNode(doc);
root_elmt := xmldom.createElement(doc, 'elencoClienti');
root_node := xmldom.appendChild(main_node, xmldom.makeNode(root_elmt));
xmldom.setAttribute(root_elmt, 'xmlns', 'indirizzo_namespace');
Then i add more than one node to root node, and finally i find in all level-one-parent of a root this attribute
xmlns=""
output example:
<?xml version="1.0" encoding="UTF-8"?>
<elencoClienti xmlns="indirizzo_namespace">
<elenco_pratiche xmlns="">
<rdl>
<id>122</id>
<tipo>PRDL</tipo>
<tran_comm>RDR</tran_comm>
<tipo_lav>TEST</tipo_lav>
<via>Maria Pia</via>
<codice_presa>5003241303200</codice_presa>
<data_protocollo>01/07/2000</data_protocollo>
</rdl>
</elenco_pratiche>
<esito_ricerca xmlns="">
<esito>OKEL</esito>
</esito_ricerca>
</elencoClienti>
both elenco_pratiche and esito_ricerca nodes have attribute xmlns="".
How can i remove that?
Thanks in advance

I don't have installed DBMS_XMLDOM, the only class I can use is XMLDOM...
My problem seems to be a bug of this class..
So that i solved the problem in this way (my procedure has to write out a xml reply into a clob):
--after to write xml into a clob:
dbms_lob.createtemporary(output_clob,true);
xmldom.writeToClob(doc, output_clob);
xmldom.freeDocument(doc);
-- I remove unwanted attribute
output_clob := REPLACE(output_clob,' xmlns=""','');
Sometimes ignorance is a solution... ;-)
I will install dbms_xmldom and i will try to find solution, but now it seems a good patch
