title: Extract JSON-response into parameter
body: <p>I need to extract this specific JSON-field into a parameter for my performance test in Visual Studio:</p>
  
  <p>"ExamAnswerId": "757a3735-e626-412b-934c-e577c6963d51"</p>
  
  <p>the problem occurs when I try to do this manually by right clicking the response and click "add extraction rule". The text is split up into 3 different rows with lots of unreadable numbers next to it like this:
  "0x00000000  7B  22  45  78  61  6D  41  6E  73  77 65  72  49  64  22  3A {"ExamAnswerId":
  0x00000010  22  37  35  37  61  33  37  33  35  2D  65  36  32  36  2D  34    "757a3735-e626-4</p>
  
  <p>This will sound dumb, but I somehow need to extract 3 different parameters, only because I can't copy/paste it -- and this is also where I think I fail. </p>
  
  <p>the ExamAnswerId is important for me to fullfill another webrequest later on, but I can't seem to pass it on properly. </p>
  
  <p>all input greatly appreciated !</p>
