XML Linq读取多个节点

Question

I'm trying to extract data from a wordpress blog xml feed, this is the format of the xml: http://brockallen.com/category/asp-net/feed/

var xElements = XElement.Parse(ResponseText);
var blogs = (from temp in xElements.Elements()
             select new 
             {
                 Title = temp.Element("item").Element("title").Value,
                 URL = temp.Element("item").Element("link").Value,
                 Image = temp.Element("item").Element("media:content").Value
             }).FirstOrDefault();

How do I get them all, and store them in to an object?

Error on media:content is saying The ':' character, hexadecimal value 0x3A, cannot be included in a name.`

When I remove that line, it only gets one, when there are more, even after removing FirstOrDefault()

Answer 1

Your are working on the wrong level of the document. Also you need an namespace.

  XNamespace media = "http://search.yahoo.com/mrss/";
  var items =
  from channelElement in XElement.Parse(ResponseText).Element("channel").Elements("item")
  select new {
    Title = channelElement.Element("title").Value,
    Url = channelElement.Element("link").Value,
    MediaItems = (
        from mediaItemElement in channelElement.Elements(media + "content")
        select new {
            url = mediaItemElement.Attribute("url").Value,
            medium = mediaItemElement.Attribute("medium").Value
            }
        ).ToList()
  };

Try this...updated with namespace for querying content element

    // var xDoc = XDocument.Load(@"<your xml location>");
    var xDoc = XDocument.Parse("<your xml string>");
    XNamespace ns = "http://search.yahoo.com/mrss/";

    var blogs = (from temp in xDoc.Descendants().Elements("item")
                 select new
                 {
                     Title = temp.Element("title").Value,
                     URL = temp.Element("link").Value,
                     Image = temp.Element(ns + "content").Value
                 });
