Is there a best practice for adding namespacing to xml output?  I effectively need my output to look like this:

<ns0:Visit xmlns:ns0="http://my.url">
  <ns0:PatientFirstName>First</ns0:PatientFirstName>
  <ns0:PatientLastName>Last</ns0:PatientLastName>
  <ns0:InsurancePlans>
    <ns0:InsurancePlan>
      <ns0:PlanOrder>1</ns0:PlanOrder>
      <ns0:Name>Medicaid</ns0:Name>
    </ns0:InsurancePlan>
    <ns0:InsurancePlan>
      <ns0:PlanOrder>2</ns0:PlanOrder>
      <ns0:Name>BlueCross</ns0:Name>
    </ns0:InsurancePlan>
  </ns0:InsurancePlans>
</ns0:Visit>

...but when i attempt to add child elements using setNode and include the "ns0:" I get errors.  I've found that when I create my xml message I can give it a template that includes the namespacing, but in doing that i don't always know how many InsurancePlan elements I'll need to output--as such, my template only specs out one.  when I try to do a message.addChild I run into issues again with setNode.

Here is my template:

<ns0:Visit xmlns:ns0="http://my.url">
    <ns0:PatientFirstName></ns0:PatientFirstName>
    <ns0:PatientLastName></ns0:PatientLastName>
    <ns0:InsurancePlans>
        <ns0:InsurancePlan>
            <ns0:PlanOrder></ns0:PlanOrder>
            <ns0:Name></ns0:Name>
        </ns0:InsurancePlan>
    </ns0:InsurancePlans>
</ns0:Visit>

...and here is some brief sample code

message = qie.createXMLMessage(qie.getVariable('XmlTemplate'), "UTF-16");
message.setNode("/Visit/PatientFirstName", source.getNode("/patient/firstName"));
message.setNode("/Visit/PatientLastName", source.getNode("/patient/lastName"));
message.setNode("/Visit/InsurancePlans", "InsurancePlan", 1, true);
var insCount = source.getCount("/insurance");
var insObject = qie.parseJSONString(source.getNode("/insurance"));
for (var insCounter = 1; insCounter <= insCount; insCounter++) {
   var insRoot = "/[" + insCounter + "]";
   var insuranceName = insObject.getNode(insRoot + "/name");
   if (StringUtils.length(insuranceName) > 0) {
        message.addChild("/Visit/InsurancePlans", "InsurancePlan", "");
        var msgInsRoot = "/Visit/InsurancePlans/InsurancePlan[" + insCounter.toString() + "]";
        if (insCounter === 1)
        {
          msgInsRoot = "/Visit/InsurancePlans/InsurancePlan";
        }
       message.setNode(msgInsRoot + "/PlanOrder", insObject.getNode(insRoot + "/position"));
       message.setNode(msgInsRoot + "/Name", insuranceName);
   }
}

When I do it that way my second InsurancePlan values end up without the namespacing (though my first ones get it)

If you addChild before you set the value you can include the namepsace.

 

message.setNode("/Visit/PatientFirstName", source.getNode("/patient/firstName"));
message.setNode("/Visit/PatientLastName", source.getNode("/patient/lastName"));
message.setNode("/Visit/InsurancePlans", "InsurancePlan", 1, true);
var insCount = source.getCount("/insurance");
var insObject = qie.parseJSONString(source.getNode("/insurance"));

for (var insCounter = 1; insCounter <= insCount; insCounter++) {
   var insRoot = "/[" + insCounter + "]";
   var insuranceName = insObject.getNode(insRoot + "/name");
   var position = insObject.getNode(insRoot + "/position");
   if (StringUtils.isNotBlank(insuranceName)) {
      message.addChild("/Visit/InsurancePlans", "ns0:insurance");
      
      message.addChild("/Visit/InsurancePlans/insurance["+insCounter+"]", "ns0:Name");
      message.setNode("/Visit/InsurancePlans/insurance["+insCounter+"]/Name", insuranceName);
      
      message.addChild("/Visit/InsurancePlans/insurance["+insCounter+"]", "ns0:position");
      message.setNode("/Visit/InsurancePlans/insurance["+insCounter+"]/position", position);
   }
}
