Hi,
I am using the dbms_xmldom package to generate xml files (specific structure).
Below is the code but It produces nothing (dbms_output does not return) : 
DECLARE
    doc xmldom.DOMDocument; 
    main_node xmldom.DOMNode; 
    root_node xmldom.DOMNode; 
    root_elmt xmldom.DOMElement;
	
    transmissionHeaderNode xmldom.DOMNode; 
    transmissionHeaderElement xmldom.DOMElement;
    item_node xmldom.DOMNode; 
    item_elmt xmldom.DOMElement;
    item_text xmldom.DOMText; 

    buffer_problem          CLOB; 
 
BEGIN
 
   doc := xmldom.newDOMDocument; 
   main_node := xmldom.makeNode(doc);
   xmldom.setversion(doc,'1.0');
   root_elmt := xmldom.createElement(doc, 'InvoiceTransmission'); 
   root_node := xmldom.appendChild( main_node, xmldom.makeNode(root_elmt)); 

   transmissionHeaderElement := xmldom.createElement(doc, 'TransmissionHeader'); 
   transmissionHeaderNode := xmldom.appendChild(root_node, xmldom.makeNode(transmissionHeaderElement));
   
   item_elmt := xmldom.createElement(doc, 'TransmissionDateTime'); 
   item_node := xmldom.appendChild(transmissionHeaderNode, xmldom.makeNode(item_elmt));
   item_text := xmldom.createTextNode(doc, TO_CHAR(SYSDATE,'DD-MM-YYYY')); 
   item_node := xmldom.appendChild(item_node, xmldom.makeNode(item_text));
   
   item_elmt := xmldom.createElement(doc, 'IssuingOrganiszationID'); 
   item_node := xmldom.appendChild(transmissionHeaderNode, xmldom.makeNode(item_elmt));
   item_text := xmldom.createTextNode(doc,'0258'); 
   item_node := xmldom.appendChild(item_node, xmldom.makeNode(item_text));

   item_elmt := xmldom.createElement(doc, 'Version'); 
   item_node := xmldom.appendChild(transmissionHeaderNode, xmldom.makeNode(item_elmt));
   item_text := xmldom.createTextNode(doc, 'IATA:ISXMLInvoiceV3.0'); 
   item_node := xmldom.appendChild(item_node, xmldom.makeNode(item_text));
  
    xmldom.writetobuffer(doc, buffer_problem);
    dbms_output.put_line(buffer_problem);
    xmldom.freeDocument(doc); 
 
 END;

That's strange because when I remove a code part like : 
   item_elmt := xmldom.createElement(doc, 'Version'); 
   item_node := xmldom.appendChild(transmissionHeaderNode, xmldom.makeNode(item_elmt));
   item_text := xmldom.createTextNode(doc, 'IATA:ISXMLInvoiceV3.0'); 
   item_node := xmldom.appendChild(item_node, xmldom.makeNode(item_text));

I can get the ouput xml : 
<?xml version="1.0"?>
<InvoiceTransmission>
  <TransmissionHeader>
    <TransmissionDateTime>26-10-2010</TransmissionDateTime>
    <IssuingOrganiszationID>0258</IssuingOrganiszationID>
  </TransmissionHeader>
</InvoiceTransmission>


I don't know if it's a problem with xmldom or with dbms_output package...

Please someone can help me ?

It works for me:

PL/SQL procedure successfully completed.

I think it is a SQL*Plus setting issue.
execute the following and retry:
set long 10000

Please when something "does not work", copy and paste your session as we did in all your questions.
