Hi,

you can convert that XML to JSON and then parse the JSON

For converting xml to json refer this link

Converting XML to JSON

Script I tried

var jsonString = '{"set1":{"attr1":"123"},"set2":{"attr2":"xyz"},"attr3":"value1","attr4":"value2"}';

var parser = JSON.parse(jsonString);

var attr1Value = parser.set1.attr1;

var attr2Value = parser.set2.attr2;

var attr3Value = parser.attr3;

var attr4Value = parser.attr4;

gs.info(attr1Value);
gs.info(attr2Value);
gs.info(attr3Value);
gs.info(attr4Value);

Output:
