title: SQL Server Regular expressions in T-SQL
body: <p>Is there any regular expression library written in T-SQL (no CLR, no extended <code>SP</code>, pure T-SQL) for SQL Server, and that should work with shared hosting?</p>
  
  <p>Edit:</p>
  
  <ul>
  <li>Thanks, I know about <code>PATINDEX</code>, <code>LIKE</code>, <code>xp_</code> <code>sps</code> and CLR solutions</li>
  <li>I also know it is not the best place for regex, the question is theoretical :)</li>
  <li>Reduced functionality is also accepted</li>
  </ul>
