title: Displaying corresponding XML nodes from different blocks
body: <p>lets say I have the following XML block..</p>
  
  <pre><code>&lt;items&gt;
      &lt;books&gt;
          &lt;book&gt;
              &lt;name&gt;a&lt;/name&gt;
              &lt;author&gt;b&lt;/author&gt;
          &lt;/book&gt;
          &lt;book&gt;
              &lt;name&gt;d&lt;/name&gt;
              &lt;author&gt;e&lt;/author&gt;
          &lt;/book&gt;
      &lt;/books&gt;
  
      &lt;infos&gt;
          &lt;info&gt;
              &lt;id&gt;1&lt;/id&gt;
              &lt;year&gt;c&lt;/year&gt;
          &lt;/info&gt;
          &lt;info&gt;
              &lt;id&gt;2&lt;/id&gt;
              &lt;year&gt;f&lt;/year&gt;
          &lt;/info&gt;
      &lt;/infos&gt;
  &lt;/items&gt;
  </code></pre>
  
  <p>Where each instance of 'info' corresponds to an instance of 'book'.  If items/infos/info/id refers to the position of a book element.<br>
  I'm trying to output the following...  </p>
  
  <pre><code>a  
  b  
  c  
  
  d
  e
  f
  </code></pre>
  
  <p>Thanks in advance... Any help would be apprechiated!</p>
