How to generate XML string?

[amala2]

Hi,

I want to generate a XML for few fields and is having issues when the value of a field is empty? I'm generating the below XML 

For Example: <Number>SNN1234</Number>

But when the Number is empty, Its generated as <Number></Number>. I want it as <Number/>

Please advise.

Thanks

How are you generating XML?

Here is a code snippet

var x = GlideRecord('cmdb_ci_computer');
x.query();
x.next();
var s = gs.unloadRecordToXML(x, true);
gs.print (s);

output

 <?xml version="1.0" encoding="UTF-8"?><record_update sys_domain="global" table="cmdb_ci_computer">
    <cmdb_ci_computer action="INSERT_OR_UPDATE">
        <asset display_value="P1000503 - Apple MacBook Pro 15&quot;">04a96c0d3790200044e0bfc8bcbe5db3</asset>
        <asset_tag>P1000503</asset_tag>
        <assigned>2016-11-21 07:00:00</assigned>
        <assigned_to display_value="Eduardo Bellendir">92826bf03710200044e0bfc8bcbe5dbb</assigned_to>
        <assignment_group/>

I am working in a scoped app. This is the code I am using:

var xmlDocString = '';
var grDoc = new GlideRecord(tablename);
grDoc.addEncodedQuery('active=true');
grDoc.query();
while (grDoc.next()) {
xmlDocString += '<application_number>' + grDoc.getDisplayValue('application_number') + '</application_number><br/>';
}

gs.info(xmlDocString);

var xmlDocString = '';
var grDoc = new GlideRecord(tablename);
grDoc.addEncodedQuery('active=true');
grDoc.query();
while (grDoc.next()) {
	if(grDoc.getDisplayValue('application_number') == ''){
		xmlDocString += '<application_number/>';
	}
	else
	{
		xmlDocString += '<application_number>' + grDoc.getDisplayValue('application_number') + '</application_number><br/>';
	}
}

gs.info(xmlDocString);
