title: find and replace quotes inside quotes with regular expression in a JSON file
body: <p>I have a very large JSON file with almost 30000 records. 
  One record looks something like this:</p>
  
  <pre><code>{
    "adlibJSON": {
      "recordList": {
        "record": [
          {
            "@attributes": {
              "priref": "4372",
              "created": "2011-12-09T23:09:57",
              "modification": "2012-08-11T17:07:51",
              "selected": "False"
            },
            "acquisition.date": [
              "1954"
            ],
            "documentation.title": [
              "A lot of text with a lot of extra double quotes like "this" and "this""
            ] ... ...
  </code></pre>
  
  <p>The problem is that there are a lot of values with extra double quotes in it. This can be 1 double quote, but also 2 or 3 extra double quotes. See the value of <code>"documentation.title"</code> in my example.</p>
  
  <p>How do i find all these quotes and replace them with regular expression. 
  I use sublime text 2 to do my regular expression, but i don't know how to solve this specific problem.</p>
