title: How do find next occurrence of a string after a string position?
body: <p>I find an occurrence of a string, let's say Chocolate, in a string, and I'm trying to find if chocolate is part of anchor text inside a link.  The easiest way I considered doing this is finding the next &lt; character to see if it is followed by /a> </p>
  
  <p>I don't know how to find the next occurrence of a string from a string position number.  Is there a function that does this easily?</p>
