Answer 1

To save the extracted value to a csv file follow the below procedure.

1. Remove Regex extractor as we will extract from the response using JSR223 Post Processor

2. Add JSR223 Post Processor and paste the below code in the script section. Choose language as " Groovy 2.4.12 / Groovy scripting engine 2.0 "

    import java.util.regex.Matcher; import java.util.regex.Pattern; import java.io.FileWriter; import java.io.Writer; String stringToSearch=prev.getResponseDataAsString(); Pattern p = Pattern.compile('value="(PR.+?)"'); Matcher match = p.matcher(stringToSearch); if (match.find()) { def value = match.group(1) log.info('------------------') log.info(value) // to check in the jmeter log for the extracted data vars.put('a', value) } //get path of csv file (creates new one if its not exists) FileWriter fileWriter = new FileWriter("C:\\Users\\Tarik\\Desktop\\example.csv",true); // true to append BufferedWriter out = new BufferedWriter(fileWriter); out.write(vars.get("a")); out.close(); fileWriter.close();

This worked, thank you. Used 'println' instead of 'write' to have consecutive values in a new line.
