title: Splitting strings at specific positions
body: <p>I got a little problem here, i'm looking for a better way to split Strings.
  For example i receive a String looking like this.</p>
  
  <pre><code>0000JHASDF+4429901234ALEXANDER
  </code></pre>
  
  <p>I know the pattern the string is built with and i have an array of numbers like this.</p>
  
  <pre><code>4,5,4,7,9
  0000 - JHASDF - +442 - 9901234 - ALEXANDER
  </code></pre>
  
  <p>It is easy to split the whole thing up with the String MID command but it seems to be slow when i receive a file containing 8000 - 10000 datasets.
  So any suggestion how i can make this faster to get the data in a List or an Array of Strings?
  If anyone knows how to do this for example with RegEx.</p>
