title: Parsing String in C
body: <p>I need to parse my string but my delimiters are all characters excepts a-z and A-Z.
  How can I do that? </p>
  
  <p>I thought strtok but I must write all character as delimiter and it would be too long.
  Exampe string:</p>
  
  <pre><code>Ax'cda2hsa+AsF(f/a as
  </code></pre>
  
  <p>It needs to be split into: "Ax" "cda" "hsa" "AsF" "f" "a" "as"</p>
  
  <p>Is there any parsing function in C libraries which i can write my all delimeters as an interval ?</p>
