Comparing the SOAP UI and database response values stored in arraylist and storing the result

File fr = new File("C:\\ViewBANTestData.xls")
Workbook wk = Workbook.getWorkbook(fr);
WritableWorkbook workbook1 = Workbook.createWorkbook(fr,wk)
WritableSheet sheet= workbook1.getSheet("Sheet1");

def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context )
def holder = groovyUtils.getXmlHolder( "SOAP Request#Response" )
def GPSRequest = context.expand('${SOAP Request#Request}')
def GPSResponse = context.expand('${SOAP Request#Response}')
def slurper1 = new XmlSlurper()

def DBholder = groovyUtils.getXmlHolder( "JDBC Request#ResponseAsXml" )

def xmlUtil = new com.eviware.soapui.support.xml.XmlUtils();
def nodes = holder.getDomNodes( "//*" );
def DBnodes = DBholder.getDomNodes( "//*" );

def list = []
def XMLlist = []
def DBXMLlist = []
for( node in nodes )
{
if(!(node.getNodeName().toString().contains("m:serviceCodeEnglishDescription") || node.getNodeName().contains("m:serviceCodeFrenchDescription") || node.getNodeName().contains("m:transpromoStatus")) )
{
def value = com.eviware.soapui.support.xml.XmlUtils.getNodeValue( node )
if((value!=null))
{
if( !(value.isAllWhitespace()))
XMLlist.add(value)
}
}
}
def Slist = XMLlist.size()

log.info "SOAP UI RESPONSE" + XMLlist

for( node in DBnodes )
{
def DBvalue = com.eviware.soapui.support.xml.XmlUtils.getNodeValue( node )
if((DBvalue!=null))
{
if(!(DBvalue.isAllWhitespace()))
{
DBXMLlist.add(DBvalue.trim())
}
}
}
log.info "DB RESPONSE =" + DBXMLlist
def DBSlist=DBXMLlist.size()

I have above code in that  my SOAP UI Response is getting stored in XMLlist

"SOAP UI RESPONSE" + XMLlist

and my Database response is stored in DBXMLlist 

DB RESPONSE =" + DBXMLlist

like below

SOAP UI RESPONSE[5275495390, 1219 CHRISTIE CIR, MILTON, ON, Sterling Insurance Brokers, L9T6V4, 527749, NM1, B, Y, NM1IPBB]
DB RESPONSE =[5275495390, 1219 CHRISTIE CIR, MILTON, ON, Sterling Insurance Brokers, L9T6V4, 527749, NM1, B, Y, NM1IPBB]

So till here my script is working fine

but after this i want to compare each value of SOAP UI Response and Database Response for multiple iterations and store the result for each iteration in Excel.
