Improve EvaluateJSONPath docs

    XMLWordPrintableJSON

Details

    Description

      {"http.request.uri":"/","http.context.identifier":"2fd145e5-1a7f-40d9-a187-5e5eb2734d0e","http.query.string":"a=1"}

      To extract JSON fields with '.'s in the key, you must use a particular escape sequence: $.['http.param.a']

      The EvaluateJSONPath docs could use a blurb with this information.
