title: Xpath up one level
body: <p>i would like to use this XPath expression</p>
  
  <pre><code>/moviedb/movie/title[@lang="english"] | /moviedb/movie/title[@lang="english"]/..runtime
  </code></pre>
  
  <p>I would like to filter out movies with attribute "english" in title and their runtime, but i dont know how to go back to /moviedb/movie once I am in /moviedb/movie/title
  full XML file:</p>
  
  <pre><code>&lt;moviedb&gt;
  &lt;movie&gt;
      &lt;imdbid&gt;tt0838283&lt;/imdbid&gt;
      &lt;genres&gt;Comedy&lt;/genres&gt;
      &lt;languages&gt;English,Spanish&lt;/languages&gt;
      &lt;country&gt;USA&lt;/country&gt;
      &lt;rating&gt;6.8&lt;/rating&gt;
      &lt;runtime&gt;106&lt;/runtime&gt;
      &lt;title lang="spanish"&gt;Step Brothers&lt;/title&gt;
      &lt;year&gt;2008&lt;/year&gt;
    &lt;/movie&gt;
    &lt;movie&gt;
      &lt;imdbid&gt;tt2886734&lt;/imdbid&gt;
      &lt;genres&gt;Drama&lt;/genres&gt;
      &lt;languages&gt;English&lt;/languages&gt;
      &lt;country&gt;USA&lt;/country&gt;
      &lt;rating&gt;7.5&lt;/rating&gt;
      &lt;runtime&gt;125&lt;/runtime&gt;
      &lt;title lang="english"&gt;A Life, Taken&lt;/title&gt;
      &lt;year&gt;2014&lt;/year&gt;
    &lt;/movie&gt;
  &lt;/moviedb&gt;
