title: Child nodes to comma delimited string with Xpath?
body: <p>I have XML that looks like this:</p>
  
  <pre><code>&lt;node1&gt;
   &lt;item&gt;hello&lt;/item&gt;
   &lt;item&gt;world&lt;/item&gt;
  &lt;/node1&gt;
  </code></pre>
  
  <p>I would like this to output the following using an XPath expression:</p>
  
  <pre><code>hello, world
  </code></pre>
  
  <p>Is this possible with XPath 1.0? I have been looking around but unable to find anything. </p>
  
  <p>Thanks,
  Cinegod</p>
