Set a node value in all test step's requests of all test cases in a test suites

Hi to everyone,

 

this is the code for what I'm trying to do: set a node value in all test step's requests of all test cases in a test suite.

 

def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context )
def AlltestCases = testRunner.testCase.testSuite.project.testSuites[testRunner.testCase.testSuite.name]

0.upto(AlltestCases.getTestCaseCount())
	{ AlltestCases.getTestCaseList().each{
		it.getTestStepList().each{
			if(it.getClass()== com.eviware.soapui.impl.wsdl.teststeps.WsdlTestRequestStep){
				
				if(it.getName().toLowerCase().contains("verify")){

				step = groovyUtils.getXmlHolder("${it.getName()}"+"#Request")
				step.setNodeValue("//*:Name/text()", "\$"+"{#TestSuite#NAME_ID}")
				step.updateProperty()
					}
				}
			}
		}
	}

This groovy script is in the first test case and I get an error (XmlException: Unexpected Element: CDATA) as soon as the script try to modify the same tag in the second test case. What did i do wrong?
