title: bash - xmlstarlet -v to $variable
body: <pre><code>wget ${RSS_URL} -O - 2&gt;/dev/null | xmlstarlet sel -t -m "/rss/channel/item" -v "title" -n -v "link" -n -n
  </code></pre>
  
  <p>That line prints out the title (-v "title) and the url (-v "link") of entries in a rss feed I have.
  I want to store the title and url into separate variables ($title and $url for example) so I can use them for curl later.</p>
  
  <p>How can I do this?</p>
