title: Regex: Match if strings starts with a letter or number and then
body: <p>I'm wanting to match a string if begins with either a letter or number, and from there I want to count the string (excluding whitespaces), and if it's over 5 characters, match it.</p>
  
  <p>I believe I'm pretty close, my current regex is:</p>
  
  <pre><code>\s*(?:\S[\t ]*){5,}
  </code></pre>
  
  <p>What I need to add, is making sure the string starts with either a letter or number (or if it begins with a whitespace, make sure the following character is a letter or number.)</p>
