More useful if we should save an error in Response:

import com.eviware.soapui.support.XmlHolder
import java.text.MessageFormat
import org.apache.commons.lang.ObjectUtils

def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context )
def retrieve = groovyUtils.getXmlHolder("MyTestRequest#Response" )

if (!ObjectUtils.equals(retrieve.getNodeValue("//*:xpath"), "string")){
 def currentTime = System.currentTimeMillis()
 def fullFilePath = context.expand('${projectDir}') + File.separator + "Fail-"+currentTime+".xml"
 def reportFile = new File(fullFilePath)
 if (!reportFile.exists())
 {
  reportFile.createNewFile()    
  reportFile.append((Object)retrieve.getPrettyXml(), 'UTF-8')
 }
}
