title: How to join two extracted values with xidel?
body: <p>I use the following to extract two values using <code>xidel -e</code>.</p>
  
  <ul>
  <li><code>'//input[@name="qid"]/@value[1]'</code></li>
  <li><code>"//span[@id='trueFinalResultCount']"</code></li>
  </ul>
  
  <p>But I'd like to put the two results into a TSV format.</p>
  
  <pre><code>result1&lt;TAB&gt;result2
  </code></pre>
  
  <p>Could anybody show me how to combine the above two expressions? (I tried the following. But it doesn't work.)</p>
  
  <p><code>'join((//input[@name="qid"]/@value[1], //span[@id='trueFinalResultCount'][1]), x:cps(9))'</code></p>
