I could able to convert xml response of restful service into JSON response using following method. 1. Download JSON jar from this page: [http://mvnrepository.com/artifact/org.json/json/20140107](http://mvnrepository.com/artifact/org.json/json/20140107) 2. Import .jar file into your project: [https://docs.katalon.com/display/KD/External+Libraries](https://docs.katalon.com/display/KD/External+Libraries) 3. Adjust your test case using conversion script to convert XML to JSON. Below is sample script where ‘xmlJSONObj.toString(textIndent)’ is the final result after conversion. import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject import org.json.JSONObject as JSONObject import org.json.XML as XML import com.kms.katalon.core.testobject.ResponseObject import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS ResponseObject response = WS.sendRequest(findTestObject(‘REST\_CommentDetails’)) int textIndent = 2 JSONObject xmlJSONObj = XML.toJSONObject(response.getResponseBodyContent()) xmlJSONObj.toString(textIndent) But when I tried to verify Converted response with database, I am getting following Error.Please give me some suggestion on this problem. groovy.lang.MissingMethodException: No signature of method: static com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords.verifyElementPropertyValue() is applicable for argument types: (java.lang.String, java.lang.String, java.lang.String) values. ---

The error means that the parameters passed into the function is not correct. you need to double check on this issue. ---

In the above method converted response is storing in ‘’ xmlJSONObj.toString(textIndent)’. and I am assigning that into a variable of the type Object called response and using it for verification as below. Object response = xmlJSONObj.toString(textIndent) WS.verifyElementPropertyValue(response, ‘response.data.id’, ‘\*\*\*\*\*’) Is this way is correct? ---

You are using XML class so you need to ensure that the function in use is correct. If you use Katalon Studio, you can follow the instruction at [https://docs.katalon.com/katalon-studio/tutorials/verify-api-responses.html#verifying-soap-response-in-xml-format](https://docs.katalon.com/katalon-studio/tutorials/verify-api-responses.html#verifying-soap-response-in-xml-format) to verify the response properties. ---

Above link explains verifying REST response in JSON format and SOAP response in XML format. But what I need is Verifying REST response in XML format. ---

XML format you have the same verification. Did you try and it did not work? ---

Yes I tried.it failed to identify values from the response. ---

This is the code snippet i am using for verification. where response will contain the response in xml format.\*\*\*\*\*\* will be the value fetched from database.and the ‘datalist.data[0].id’ is the xml path of a id from the response. WS.verifyElementPropertyValue(response, ‘datalist.data[0].id’, ‘\*\*\*\*\*’) Error message is: Reason: com.kms.katalon.core.exception.StepFailedException: Unable to verify element property value (Root cause: com.kms.katalon.core.exception.StepFailedException: Expected element property value ‘\*\*\*\*\*’ is not equal with actual property value ’ ') at com.kms.katalon.core.keyword.internal.KeywordMain.stepFailed(KeywordMain.groovy:36) at com.kms.katalon.core.keyword.internal.KeywordMain.stepFailed(KeywordMain.groovy) at com.kms.katalon.core.keyword.internal.KeywordMain.runKeyword(KeywordMain.groovy:56) ---

Because of this only i converted XML response into JSON and tried to verify with json values. Object response = xmlJSONObj.toString(textIndent) WS.verifyElementPropertyValue(response, ‘response.data.id’, ‘\*\*\*\*\*’) and getting this error: groovy.lang.MissingMethodException: No signature of method: static com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords.verifyElementPropertyValue() is applicable for argument types: (java.lang.String, java.lang.String, java.lang.String) values. ---

There is no real benefit to convert the XML response in Json. Just extract whatever you need from it using XMLSlurper (or Parser), see: [http://groovy-lang.org/processing-xml.html](http://groovy-lang.org/processing-xml.html)
