extract value from soap response

I modify the groovy script as follow:
def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context )
def response = context.expand( '${searchRequest APT NAKED#Response}' )
def holder = groovyUtils.getXmlHolder( response )
def cdata = holder.getDomNode('//response/text()').nodeValue
def holder2 = groovyUtils.getXmlHolder( cdata )
def errorCode = holder2.getDomNode('//dsml:attr[@name='errorCode']/dsml:value/text()').nodeValue
log.info errorCode

I have the following error:

Thu Feb 14 12:37:33 CET 2013:ERROR:An error occured [startup failed:
Script1.groovy: 6: unexpected token: errorCode @ line 6, column 56.
