title: RegEx Removing Span tags from HTML
body: <p>I need some RegEx for removing span tags with a specific class including the end tag but don't want to remove what's in between ...
  I do not want to remove any other span tags</p>
  
  <p>I cannot come up with it since I tend to forget the RegEx Tricks :(</p>
  
  <p>I have this </p>
  
  <pre><code>&lt;span class="SpellE"&gt;system_user.user_name&lt;/span&gt;
  &lt;span&gt;This is some text&lt;/span&gt;
  &lt;Span class="OtherCLass"&gt;Some other text&lt;/span&gt;
  &lt;span class="SpellE"&gt;system_user.userid&lt;/span&gt;
  </code></pre>
  
  <p>And I want this result</p>
  
  <pre><code>system_user.user_name
  &lt;span&gt;This is some text&lt;/span&gt;
  &lt;Span class="OtherCLass"&gt;Some other text&lt;/span&gt;
  system_user.userid
  </code></pre>
  
  <p>Yes I need to tidy up some messy MS Html :)</p>
  
  <p>Thanks in advance</p>
