Having trouble getting a node value

I need a few node values, the script assertion below gives me the same (first) node value, and if I try (in the secondResponse) something like ("//Chassis:eventList/Chassis:eventList/CT:event/CT:message") the return value is null.

 Any suggestions on how I get the second Node value if my (example - excerpt) response appears as follows?:

---------------------Soap response template--------------------------------------------

<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<Chassis:getReportedEventsResponse>
<Chassis:eventList>
<CT:event>
<CT:name>GoodCommunicate</CT:name>
<CT:severity>FIRST-EVENT</CT:severity>
<CT:message>COMM SUCCESS</CT:message>
<CT:filename>svc/Service/ServiceSub.cpp</CT:filename>
<CT:lineNumber>22</CT:lineNumber>
</CT:event>
</Chassis:eventList>
<Chassis:eventList>
<CT:event>
<CT:name>CannotCommunicate</CT:name>
<CT:severity>SECOND-EVENT</CT:severity>
<CT:message>Failed Time</CT:message>
<CT:filename>svc/Service/ServiceSub.cpp</CT:filename>
<CT:lineNumber>32</CT:lineNumber>
</CT:event>

----------------------------------Script assertion--------------------------------------------

def groovyUtils = new com.eviware.soapui.support.GroovyUtils(context)

def holder = groovyUtils.getXmlHolder('getReportedEvents #Response')

//send each event to a variable
def firstEvent = holder.getNodeValue("//CT:event/CT:message")
log.info("\t\t$firstEvent\r\n")

def secondEvent = holder.getNodeValue("//CT:event/CT:message")
log.info("\t\t$secondEvent\r\n")
