title: How to use regularexpression for this example?
body: <p>I am trying to write regular expression for this line:</p>
  
  <p><code>-  5.0   -  4.0   -  3.0  ... +  12.0</code></p>
  
  <p>That It could group floats with sign in a single group (-5.0,-4.0...)</p>
  
  <p>I have tried:</p>
  
  <p><code>\s*([+](?:\s)*\d*[.])</code> </p>
  
  <p>But apparently It does not ignore non-capture group inside capture group.
  Any suggestion how this could be solved?</p>
