title: Using getJSON to to fetch RSS feed. I get "SyntaxError: expected expression, got '<'"
body: <p>I'm trying to fetch news from here: www.20minutos.es/rss So I'm using this:</p>
  
  <pre><code>$.getJSON("http://www.20minutos.es/sindicacion/rss?format=json&amp;callback=?", function(data) {
    alert(data);
  })
  </code></pre>
  
  <p>and this:</p>
  
  <pre><code>$.getJSON("http://www.20minutos.es/sindicacion/rss?format=xml&amp;callback=?", function(data) {
    alert(data);
  })
  </code></pre>
  
  <p>But I get:</p>
  
  <blockquote>
    <p>SyntaxError: expected expression, got '&lt;'

  <p><strong>EDIT</strong>:</p>
  
  <p>after Roland Starke's comment I have used this.</p>
  
  <p>$.get({
    url: "<a href="http://www.20minutos.es/rss?callback=" rel="nofollow">http://www.20minutos.es/rss?callback=</a>?",
    success: function(response) {alert(); console.log(response)},
    dataType: 'xml'
  });</p>
  
  <p>but I get:</p>
  
  <blockquote>
