title: Regex find then replace for all instances
body: <p>I have a string filled with script tags for Javascript files where I would like to replace all instances of .js with .min.js. I can't assume that the contents of the string will be in the same format as shown below. So I need to restrict the replace to within the src= part.</p>
  
  <p>I'm assuming that a regex would be best for this, but how would I go about doing the find, then replace for all instances?</p>
  
  <pre><code>&lt;script type=\"text/javascript\" src=\"../../Scripts/json.js\"&gt;&lt;/script&gt;&lt;script type=\"text/javascript\" src=\"../../Scripts/Logger.js\"&gt;&lt;/script&gt;  &lt;script type=\"text/javascript\" src=\"../../Scripts/PageHelper.js\"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>The other consideration would be that I wouldn't want to replace .min.js where it is already defined as min.js.</p>
