RegEx: Extract Unknown # of Numbers of Unknown Length, With Separators, and Characters to Ignore : <p>I am looking to extract numbers in the format:</p>

<blockquote>
  <p>[number]['/' or ' ' or '\' possible, ignore]:['/' or ' ' or '\'
  possible, ignore][number]['/' or ' ' or '\' possible, ignore]:...</p>
</blockquote>

<p>For example:</p>

<blockquote>
  <p>"4852/: 5934: 439028/:\23"</p>
</blockquote>

<p>Would extract: ['4852', '5934', '439028', '23']</p>
