Cant write json output to a XML file

Below is my code to specifically get values at 

 

result._source.city

node.

 

 

import net.sf.*;
import net.sf.json.*;
import net.sf.json.groovy.*;
import net.sf.json.groovy.JsonSlurper;

def ResFile ="C:/driver/Response1.xml"
def Res = context.expand( '${GetAllSchoolsForNZ#Response}' )

def slurper = new JsonSlurper()

def json = slurper.parseText Res

def countryList = json.result._source.city
log.info countryList
def j = new File(ResFile)
j.write(countryList, "UTF-8",true)

But when i execute it im gettint an error like this.

 

Spoiler
No signature of method: java.io.File.write() is applicable for argument types: (java.util.ArrayList, java.lang.String, java.lang.Boolean) values: [[Rotorua, Christchurch, Auckland, Auckland, ...], ...] Possible solutions: write(java.lang.String, java.lang.String), write(java.lang.String), wait(), size(), canWrite(), delete()


So how am i going to write my data in to a xml file? or any other file?

    I manage to write json in to a file using below code.

     

    import net.sf.*;
import net.sf.json.*;
import net.sf.json.groovy.*;
import net.sf.json.groovy.JsonSlurper;


def Res = context.expand( '${GetAllSchoolsForAustralia#Response}' )

def slurper = new JsonSlurper()

def json = slurper.parseText Res

def countryList = json.result._source.city
log.info countryList
def file = new File('D:/XXX/CityListAU.txt');
// save the response to it
file << countryList

      I hope you don't mind but your question and answer piqued my interest to why one would work but not the other, so I investigated this a bit further. So, just incase anyone else comes across this post, I believe the reason the .write method fails but the .leftShift (the "<<" operator) succeeds is that the Json Slurper returns lists or maps of objects. Thus the variable "countryList" in the above examples is a Groovy List.

       

      You can see from the Groovy File Class Java Docs that the two methods signatures are:

       

      write(String text, String charset)

      &

      leftShift(Object text)

       

      Thus you can see how you can pass a List to leftShift (Where I assume that the toString() method is called), but not to the write method which explicitly expects a string.

       

      Hope this might help somebody.
