title: How do I check if the second letter is equal to a with regex?
body: <p>I need to match a string which second letter is "a", my current regex is:
     <code>^([^a-zA-Z]*[a-zA-Z][^a-zA-Z]*)a+</code>
  but this matches less than I need, I dont even know what It doesnt match but do you know where is the problem, or if there is a better way of doing this?
  For example I need to match these:</p>
  
  <pre><code>"  kamcnn"
  ",.,ya..--/**+-00"
  "0        0   q    a"
  </code></pre>
  
  <p>I match every string that I can imagine but Im still getting lower results than I should get.
  EDIT: By "letter" I mean a character from [a-zA-Z] class.</p>
