title: Convert textNode content to a string
body: <p>Having problem with a textNode that I can't convert to a string.
  I'm trying to scrape a site and get certain information out from it, and when I use an XPath to find this text I'm after I get an textNode back.
  When I look in google development tool in chrome, I can se that the textNode itself contain the text I'm after, but how do I convert the textNode to plain text?</p>
  
  <p>here is the line of code I use:</p>
  
  <pre><code>abstracts = ZU.xpath(doc, '//*[@id="abstract"]/div/div/par/text()');
  </code></pre>
  
  <p>I have tried to use stuff like .innerHTML, toString, textContent but nothing have worked so far. </p>
