title: Search and replace regular expression in Open Office calc
body: <p>I've got something like this (in Open Office Calc):</p>
  
  <pre><code>Streetname. Number
  Streetname. Number a
  </code></pre>
  
  <p>etc.
  Now I want to delete everything in front of the number.
  So I need to do a search and replace I guess.
      ^.*?([0-9])
  this one matches Streetname. Number .. but what should I put in the replace field?
  If I do the search and replace, it deletes everything within the datafield :(</p>
