Cannot find xml element using linq query in Portable Class Library

in an console project I create an XDocument and using linq to get xml elements. See following code. I try to use the same in a portable class library but it does not work. Is there a different between console projects and portable class library by using linq to xml? 

HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync(url);
Stream strm = await response.Content.ReadAsStreamAsync();

XDocument doc = XDocument.Load(strm);

 var de = from el in doc.Descendants("outline")
          select new
          {
               title = (string)el.Element("title")
           };

In the following the xml example:

<opml version="2.0">
    <head> 
        <title>Outline of Category 41</title> 
        <dateCreated>Tue, 26 Nov 2013 10:15:02 +0100</dateCreated>
        <docs>http://www.test.com</docs>
    </head>
    <body>
        <outline title="Title1"/>
        <outline title="Title2" />
    </body> 
</opml>

You're looking for an element called title - but it's actually an attribute. The same code would fail on desktop too. You want:

title = (string)el.Attribute("title")

It's not really clear why you need an anonymous type here - you could just use:

var titles = doc.Descendants("outline")
                .Select(x => (string) x.Attribute("title"));

(You can do this with a query expression, but personally I wouldn't - query expressions are great for complex queries, but when you're just filtering or projecting they add more fluff than they save.)
