title: How to get the particular part of string matching regexp in Ruby?
body: <p>I've got a string <code>Unnecessary:12357927251data</code> and I need to select all data after colon and numbers. I will do it using Regexp.</p>
  
  <pre><code>string.scan(/:\d+.+$/)
  </code></pre>
  
  <p>This will give me <code>:12357927251data</code>, but can I select only needed information <code>.+</code> (<code>data</code>)?</p>
