I am trying to write an xml file, where i need to write the xml namespace and its URI as below.

<node xmlns:xml="http://www.w3.org/XML/1998/namespace" >
......
.....
</node>

I understand that this is completely optional and its okay if we don't write it. But i need it as that is expected to be done.

I am using xmlwrite function as using older matlab version, so don't have writeStruct function. When i am writing below code somehow matlab is not writing the xml namespace in the xml file. I think it is because it is preserved but i am not able to get any workaround it.

Can you please help on this ?

docNode = com.mathworks.xml.XMLUtils.createDocument('node');
rootElement = docNode.getDocumentElement;
rootElement.setAttribute('xmlns:xml','http://www.w3.org/XML/1998/namespace');
rootElement.setAttribute('xmlns:2xml','http://www.w3.org/XML/1998/namespace');
xmlwrite('test.xml',docNode);
