extract xml node value from a response in script assertion

Hi All

Hi have a xpath match assertion that is working perfection as below

declare namespace ns1='http://${#Project#EndpointIP}/Subscription/V1/${DataSource#id_Request}';

//ns1:ATTRIBUTES//child::ns1:NAME [text() = ‘Result']//following-sibling::ns1:VALUE

Now I want to convert it to script typed assertion, the value of Result node is stored in variable named addResult as below

The problem I have here is that the addResult is always null.  And the assertion is always false.  Not sure why.  Can anyone help me to show where it is wrong?

Here is my code

def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context )
def responseHolder = groovyUtils.getXmlHolder( messageExchange.responseContentAsXml.toString())
responseHolder.namespaces["ns1"] = "http://" + context.expand("Project#EndpointIP") + "/SUBSCRIBER/V1/" + context.expand( '${DataSource#id_Request}' )
def addResult = responseHolder.getNodeValue("//ns1:ATTRIBUTES//child::ns1:NAME [text() = ‘Result']//following-sibling::ns1:VALUE")

if (addResult == context.expand( '${DataSource#IDRequest_RESPONSE}' )){
        log.info "matching here ->" + addResult
        assert true
}else{
       log.info "Not matching here ->" + addResult
       assert false
}
