Hi,
if it's just to combine 2 different elements from your xml, you can write a simple Groovy script for this:
String xml = '''<ResponeNode>
<Node1>SOAP</Node1>
<Node2>UI</Node2>
</ResponeNode>'''
def groovyUtils = new com.eviware.soapui.support.GroovyUtils(context)
def holder = groovyUtils.getXmlHolder(xml)
String name = holder["//Node1"] + "-" + holder["//Node2"]
testRunner.testCase.testSuite.testCases["YOUR_TESTCASE"].setPropertyValue("name", name)
If your response can returned more than Node1 and Node2, you'll have parse the response, for example using XmlParser.
In case of any additional questions, feel free to ask
Regards,
Marek
