How to use multiple variables of results in one Http Request in other Http Request

Question

I just started my career as a Junior Tester

Step1: Requested XML Data using HTTP Request

    Path: /vitalhub/rest/patientlists
    ResponseData:<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
   <patientLists lastRefresh="2015-11-16T15:48:21.050-05:00" count="4">
   <patientList modifiable="false" uid="0000000000204016">
    <vhSysSrc>cerner</vhSysSrc>
    <name>Test List</name>
   </patientList>
   <patientList modifiable="false" uid="0000000000204019">
    <vhSysSrc>cerner</vhSysSrc>
    <name>123</name>
   </patientList>
   <patientList modifiable="false" uid="0000000000204021">
    <vhSysSrc>cerner</vhSysSrc>
    <name>Random Patient List</name>
   </patientList>
   <patientList modifiable="false" uid="0000000000204023">
    <vhSysSrc>cerner</vhSysSrc>
    <name>Custom List</name>
   </patientList>
   </patientLists>

Step2: Added a XpathExtractor as

   Reference Name: listName
   Xpath Query:patientLists/patientList/name/text()

Step3: Added debugSampler and these were the results

   JMeterVariables:
   JMeterThread.last_sample_ok=true
   JMeterThread.pack=org.apache.jmeter.threads.SamplePackage@393d25f8
   START.HMS=134134
   START.MS=1447267294003
   START.YMD=20151111
   TESTSTART.MS=1447709583847
   applicationDomain=VitalHubChart
   bulkCiphers=NONE
   deviceId= dev1
   devicePassword=vitalhub123
   key=55fbcb5c-f71a-42ce-995e-72a7c44145b3
   key_1=55fbcb5c-f71a-42ce-995e-72a7c44145b3
   key_matchNr=1
   listName=Test List
   listName_1=Test List
   listName_2=123
   listName_3=Random Patient List
   listName_4=Custom List
   listName_matchNr=4
   password=testcp
   sessionId=f3e8a037-d6e6-4ed4-b5db-993c713417f0
   sessionId_1=f3e8a037-d6e6-4ed4-b5db-993c713417f0
   sessionId_matchNr=1
   user=testcp
   userName=testcp
   userPass= testcp

Step4: Added an other Http Request to get the results by using ListName

  Path: /vitalhub/rest/patientLists/name/${listName_1}

By using Step4 I can just get info of a single list. I have to change it to listName_2..4 to get different list results

How can I automate these requests?

I tried using foreach loop and RegularExpressionExtractor and tried using BeanShellPostProcessor, but was unable to solve it

I would be thankful if anyone can answer my question.

Answer 1

The easiest way is using ForEach Controller configured as:

• Input Variable Prefix: listName
• Output Variable Name: anything meaningful, i.e. currentList

• Add "_" before number?: checked

  

This way you will be able to iterate all the listName_X variables:

See Using Regular Expressions in JMeter guide for another example which extracts all HTML links from web page and hits them all using ForEach Controller.
