title: regular expression to extract JSON string from text
body: <p>I'm looking for regex to extract json string from text.
   I have the text below, which contains </p>
  
  <pre><code>JSON string(mTitle, mPoster, mYear, mDate)
  </code></pre>
  
  <p>like that: </p>
  
  <pre><code>{"999999999":"138138138","020202020202":{"846":{"mTitle":"\u0430","mPoster":{"
  small":"\/upload\/ms\/b_248.jpg","middle":"600.jpg","big":"400.jpg"},"mYear"
  :"2013","mDate":"2014-01-01"},"847":{"mTitle":"\u043a","mPoster":"small":"\/upload\/ms\/241.jpg","middle":"600.jpg","big":"
  138.jpg"},"mYear":"2013","mDate":"2013-12-26"},"848":{"mTitle":"\u041f","mPoster":{"small":"\/upload\/movies\/2
  40.jpg","middle":"138.jpg","big":"131.jpg"},"mYear":"2013","mDate":"2013-12-19"}}}
  </code></pre>
  
  <p>In order to parse JSON string I should extract JSON string from the text.
  That is why, my question: Could you help me to get only JSON string
  from text? Please help.</p>
  
  <p>I've tried this regular expression with no success:</p>
  
  <pre><code>{"mTitle":(\w|\W)*"mDate":(\w|\W)*}
  </code></pre>
