So it's a Wordpress RSS with several Items.

I am using this piece of code to parse it:

namespace WordPressRSSDLL
{
    public class News
    {
        public static IList<FeedViewModel> GetBlogFeed(string feedUrl, int feedCount)
        {
            XNamespace content = XNamespace.Get("http://purl.org/rss/1.0/modules/content/"
                );
            var doc = XDocument.Load(feedUrl);
            var feeds = doc.Descendants("item").Select(x =>
            new FeedViewModel
            {
                Title = x.Element("title").Value,
                PublishedDate = DateTime.Parse(x.Element("pubDate").Value),
                Url = x.Element("link").Value,
               Content = x.Element(content + "encoded").Value
            })
            .OrderByDescending(x => x.PublishedDate)
            .Take(feedCount);
            return feeds.ToList();
        }
    }
    public class FeedViewModel
    {
        public string Title { get; set; }
        public string Url { get; set; }
        public string Content { get; set; }
        public DateTime PublishedDate { get; set; }
        public List<string> Categories { get; set; }
    }
  
}

Open in new window


Which is working quite good for the strings/Datetime. But how can I parse multiple Categories in an item? I could just parse one category, that's working, but I want a list of all categories per item...

How can I do that?

Thanks

James

This is not a direct answer to your question but I think this is a better/easier solution:

If it is regarding a RSS or ATOM feed, you can use the SyndicationFeed class to convert it. This is a class specially for RSS and ATOM feeds.

You can do like the following to load the xml from an URL:
var reader = XmlReader.Create(rssFeedUrl);
    var feed = SyndicationFeed.Load(reader);

Open in new window


From there you can iterate through the "Items" property and get everything you need.
