Hello,

I want to print xxx in the line " <two att=\"xxx\">abcd1234</two>"+

and  yah or yyy in the given string " <three boo=\"yah\" att=\"yyy\">1234abcd</three>" +

like some element in the xml string.

How can I get the desired output?

You're going to need to use XMLDocument2 | ServiceNow Developers

Something like 

/*
 * Retrieves the attribute value from the given XML.
 * Params:
 *  xmlDoc - XMLDocument2, XML document to parse
 * Returns:
 *  String, attribute value or null if not found
 */
function getAttributeKey (xmlDoc) {
  var node = xmlDoc.getNode("/test/one/two");
  if (node != null) {
    return node.getAttribute("att");
  } else {
    return null;
  }
}

// Example usage:

var xmlString = "<test>" +
                "  <one>" +
                "    <two att=\"xxx\">abcd1234</two>" +
                "    <three boo=\"yah\" att=\"yyy\">1234abcd</three>" +
                "    <two>another</two>" +
                "  </one>" +
                "  <number>1234</number>" +
                "</test>";

var xmlDoc = new XMLDocument2();
xmlDoc.parseXML(xmlString);

var attribute = getAttributeKey(xmlDoc);
if (attribute != null) {
  gs.info("The attribute value is: " + attribute);
} else {
  gs.info("The attribute value is not found.");
}

What's the business requirement here?

You can use XML parsing or convert that XML to JSON and then parse the JSON
