title: Parse words from text using Regex
body: <p>I have an HTML page that has elements such as </p>
  
  <pre><code>&lt;li id="ctl00_rpPublication_ctl61_liPublication" data-pmid="19917728"&gt;
  &lt;li id="ctl00_rpPublication_ctl62_liPublication" data-pmid="19887554"&gt;
  &lt;li id="ctl00_rpPublication_ctl63_liPublication" data-pmid="19851314"&gt;
  </code></pre>
  
  <p>I know that I can parse the page using HTML-Agility or even just doing a loop finding the index of data-pmid but I would like to accomplish this using Regex if possible. I need to read the text page and end up with a comma separated string of all of the values of data-pmid.  such as </p>
  
  <pre><code>value = 19917728,19887554,19851314
  </code></pre>
  
  <p>I can do a pattern matching of data-pmid but do not know how to get the values between the double quotes.</p>
  
  <p>The reason I would like to use Regex is that I can use the code in various places, such as vb.net or javascript.  Is this a good use for Regex?  The page could have 100 values. </p>
