title: How can I make a regex that matches any combination of "<br>", "<br/>", and "<p>" that appears at the start of a line?
body: <p>I want to match all "new line" type html tags (breaks and paragraphs) <strong>no matter how many</strong> and in what order they appear, so long as they appear at the beginning of a line.</p>
  
  <p>This regex pattern matches the <strong>first</strong> one:
      <code>^&lt;[Bb][Rr] ?/?&gt;|^&lt;[Pp]&gt;</code></p>
  
  <p>So, given this text <code>&lt;p&gt;&lt;br&gt;fred</code>, it would match the first <code>&lt;p&gt;</code> but not the immediately following <code>&lt;br&gt;</code> also.</p>
  
  <p>Note that I don't want to remove every one of these tags, but only those which appear at the beginning of the input line.</p>
