title: XRegExp: negate expression
body: <p>What is the negate expression of following <a href="http://xregexp.com/" rel="nofollow">XRegExp</a> expression?</p>
  
  <pre><code>[\\p{Alphabetic}\\p{Nd}\\{Pc}\\p{M}]+
  </code></pre>
  
  <p>I used <code>matchChain()</code> to get the words out of the sentence using above expression.</p>
  
  <p>Now I'm going to use <code>split()</code> using negate expression to get the same result but with containing delimiters for each words.</p>
