Best way to store and check a NodeList

Question

Hi,
I hope that this makes sense. In my code below, I have to, and ignoring the first one, check if the XPATH expressions are equal in first and second TSTs and second and third and so on & if they are not equal - I issue the ticket. But I don't know a way of storing the previous TSTs before it goes into the next iteration of the loop.
However I'm wondering if I'm going about it the correct manner.
    public boolean isFsiRequired(String xml) throws SITAFrameworkException, XPathExpressionException {
         boolean returnValue = false;
        // need to check that the Airline, Flight, Dep date and From/To City values,
         NodeList airLineExp = XMLUtils.queryXML(xml, "//MarketingAirline/Code");
         NodeList flightExp = XMLUtils.queryXML(xml, "//FlightNumber");
         NodeList departDateExp = XMLUtils.queryXML(xml, "//DepartureDateTime");
         NodeList fromCityExp = XMLUtils.queryXML(xml, "//DepartureAirport");
         NodeList toCityExp = XMLUtils.queryXML(xml, "//ArrivalAirport");
         System.err.println("returning returnValue == "+returnValue);
         return returnValue;
    // method is called from here
    for ( int i=0; i< totalTstCount; i++){
       if ( i == 0) {
            System.err.println("Issuing first FSI.....");
            response = sitaIssue.issueFsi(response);
       else if ( (i > 0) && (sitaIssue.isFsiRequired(command))) {                                    
                   System.err.println("Issuing another FSI.....");
               response = sitaIssue.issueFsi(response);
       else {
                   System.err.println("TSTs are equal, won't be issuing another FSI.....");
     }

I agree with Frank - for just 5 lines, simple text is probably sufficient.
However, if the point is just to pass data between two AppleScripts you could even use native AppleScript objects - for example, you could write the list (array) to the file and then read it back in directly, e.g:
Write the data:
-- create a list of any types:
set myList to {"a string", 3.14159, "foo", {name:"Joe", age:21}}
-- create a file
set f to open for access (choose file name) with write permission
-- write your (binary) data to it
write myList to f
-- and close the file
close access f
Now, separately, you can read it back:
set x to read (choose file) as list
