Jmeter- How to read an xml attribute value from the response of a HTTP Sampler

Question

How can I get the atrribute value from a response of a HTTP sampler and use that variable in other sampler?

Another issue is the HTTP sampler from which I want to get the attribute value have more than one Element with same name, so I have to loop through the entire node and fetch the value of the attribute, how can I achieve this?

Answer 1

Suppose you have :

<toto>
    <titi name="123" />
    <titi name="321" /> 
</toto>

And if I understand you want to retrieve the 2 values 123 and 321

Do the following:

• Add an XPath_Extractor as a child of HTTP Sampler:

  XPath Query : /toto/titi/@name
  Reference Name : fullAnswer
  

• Add a BeanShell Sampler:

  int number = Integer.parseInt(vars.get("fullAnswer_matchNr"));
  StringBuilder builder = new StringBuilder();
  for(int i=0;i<number;i++) {
      builder.append(vars.get("fullAnswer_"+(i+1)));
  }
  vars.put("body", builder.toString());
  

• You will obtain as JMeter variables:

  body=123321
  fullAnswer=123
  fullAnswer_1=123
  fullAnswer_2=321
  fullAnswer_matchNr=2
