Hi All,

I am trying to generate xml file.

But there is extra namespace coming in CstmrCdtTrfInitn node.

Expected :

Please see my code below

 rootNode = xmlDoc.documentElement();


 docNode = xmlDoc.createElement2('Document',"urn:iso:std:iso:20022:tech:xsd:pain.001.001.03");
 docNode.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
 xmlDoc.appendChild(docNode);

 XmlNode CstmrNode;

 CstmrNode = xmlDoc.createElement('CstmrCdtTrfInitn');
 docNode.appendChild(CstmrNode);                        //todo
 xmlElement = xmlDoc.createElement('GrpHdr');
 NodeName =  CstmrNode.appendChild(xmlElement);

Please help.

Thanks,

Priya

Extra namespace coming in document node

Hi Martin,

Thanks for your suggestion. Finally got what was wrong. I added same namespace to all the child nodes, now the extra xmlns="" is not showing in any node.

For reference :

xmlDoc = XMLDocument::newBlank(); // Create first line containing version info rootNode = xmlDoc.documentElement(); docNode = xmlDoc.createElement2('Document',"urn:iso:std:iso:20022:tech:xsd:pain.001.001.03"); docNode.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance"); xmlDoc.appendChild(docNode); CstmrNode = xmlDoc.createElement2('CstmrCdtTrfInitn',"urn:iso:std:iso:20022:tech:xsd:pain.001.001.03"); docNode.appendChild(CstmrNode); xmlElement = xmlDoc.createElement2('GrpHdr',"urn:iso:std:iso:20022:tech:xsd:pain.001.001.03"); NodeName = docNode.appendChild(xmlElement); xmlElement = xmlDoc.createElement2('MsgId',"urn:iso:std:iso:20022:tech:xsd:pain.001.001.03"); NodeMsg = NodeName.appendChild(xmlElement); xmlText =xmlDoc.createTextNode(numseq); NodeMsg.appendChild(xmlText);

Thanks,

Priya

Yes, I know you don't want any xmlns attribute there, but it doesn't mean you can ignore namespaces.

To achieve the result you want, the elements under Document must belong to the same namespace as Document. Your current problem is caused by the fact that the namespace are different; the xmlns="" attribute is added to CstmrCdtTrfInitn because the namespace must be changed from http://www.w3.org/2001/XMLSchema-instance to "". There is no xmlns="" on GrpHdr because it has the same namespace as CstmrCdtTrfInitn (= "").

You may want to learn a bit more XML namespaces before continuing.

The reason is that you didn't specify the namespace of CstmrCdtTrfInitn, therefore the namespace of CstmrCdtTrfInitn is different than the namespace of its parent node (empty vs. http://www.w3.org/2001/XMLSchema-instance).

You seem to want the same namespace for all nodes, therefore you should do that. You can, for example, use createElement2() instead of createElement(), because createElement2() has a parameter for the namespace URI.
