GroovyUtils removeDomNodes says no error, but do not see the request being updated

I am very new to groovy , and I have a input request that is one of the test step of a test suite/Test case in soap UI 4.5.1, the requirement is to remove a node based on some conditional check and write back to the test step, here is the XML:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:_0="http://...." xmlns:xsd="http://..."> <soapenv:Header/> <soapenv:Body> <PolicyPricingRequest xmlns="http://..." <Policy key="1"> PersonalPropertySection key="1"> <Cover key="1">...</Cover> <Cover key="2">...</Cover>

And I want to remove the node <Cover key="2"> So I wrote this groovy script in soapUIPro 4.5.1:

def xmlHolder = groovyUtils.getXmlHolder("PricingRequest#request")
xmlHolder.removeDomNodes("/Envelope[1]/Body[1]/PolicyPricingRequest[1]/Policy[1]/PersonalPropertySection[1]/Cover[3]")
xmlHolder.updateProperty()
log.info("done")

It prints done,but I don't see anything happening, so obviously I need to set the context or request? but did not find the right API docs for that, please kindly help anyone.

Never mind. removeNodes do not work for some reason. So, I switched to XmlParser.
