title: using regex to get the variable value of html tags
body: <p>I am trying to get a value in between certain text of html , so far not successful ,I can not use html aglity pack as it gives the data only present in between html tags </p>
  
  <pre><code>public static string[] split_comments(string html)
      {
          html = html.ToLower();
  
  
          html = html.Replace(@""""," ");
  </code></pre>
  
  <p>the actual line in html is this </p>
  
  <p>//<code>&lt;meta itemprop="rating" content="4.7"&gt; the 4.7 value changes every time and I need to get this value</code></p>
  
  <pre><code>Match match = Regex.Match(html, @"&lt;meta itemprop=rating content=([A-Za-z0-9\-]+)\&gt;$");
              if (match.Success)
              {
                  // Finally, we get the Group value and display it.
                  string key = match.Groups[1].Value;
              }
  </code></pre>
