title: Split last two set of id's from string
body: <p>I have the following string</p>
  
  <pre><code>ford-focus-albany-ny-v12356-l12205
  </code></pre>
  
  <p>I'm trying to parse the last two sets of numbers out</p>
  
  <p><code>12356</code> and <code>12205</code></p>
  
  <p>I'm using the prefix letter to define the id type since the order of those int may very. </p>
  
  <pre><code>v = vehicle id "id length may very"
  l = location id "id length may very"
  </code></pre>
  
  <p>I'd also like to add one may exist without the other. Example</p>
  
  <p><code>ford-focus-v12356</code> or <code>albany-ny-l12205</code></p>
  
  <p>I'm really not sure what the best approach to splitting the string dynamically is, my initial thought was to find the last two - and then try to parse the ints from the prefix. Anybody have any suggestions or a possible example?</p>
