Regex pattern to extract one section from JSON request

Question

My string format is,

 {
     "group By": "name",
     "time Period": {
      "from": "2015-12-29",
      "to": "2016-02-29"
     },
     "query String": "[nation]: \"India\" AND [education]: \"be",
     "geography": "NA",
     "offset": 0,
     "limit": 10
 }

From the above content I want to extract the query string value and need to display it in HTML page.I have tried to do that using Regular expression in java net beans. But I am resulting in errors. Can you please give me the regex pattern to extract query string from the above JSON ?. The Regular expression I have tried is: \"((\"|[^"])*)\"";

Thanks in advance.

Doesn't Java support JSON object operations. Using Regex is a bad practice for JSON. — Tushar, Feb 29 '16 at 14:11
I strongly advise you to take a look at [GSON](https://github.com/google/gson) to parse and use these values from Java the way they were intended. — Neil, Feb 29 '16 at 14:13

You could try JSON parser instead of regex here. org.json library can be used.

This is not the best approach. Try using some JSON parser library. If you still want to use regex, you can use the regex below:

\"query String\": \"(.*)\"
