Get media elements from RSS using SyndicationFeed

4.9k views Asked by At

I'm attempting to parse an RSS feed using C# and the SyndicationFeed class. I'm iterating over the items to get a list of SyndicationItems and that is exposing most of the feed properties, but what I cannot get out is the media:thumbnail element:

The entire media:content block is not deserialized from the XML passed in. I've iterated over the entire element extensions block using

foreach (SyndicationElementExtension extension in item.ElementExtensions)

but its not in there. Is there any way I can tell the SyndicationFeed.Load() method to also parse this block for me:

SyndicationFeed feed = SyndicationFeed.Load(xmlReader);
c# xml rss syndication-feed syndication-item

Ok.. Found your data.

Try this, where the data variable is the string you've provided.

The inner XElement.Value contains the entire media block, so you will then need to query it and select which-ever element you want.

The Dump() method is an extension method available from LinqPad which is where I do my debugging.

var rss = new Rss20FeedFormatter();

var elements = rss.Feed.Items.SelectMany(s => s.ElementExtensions.Select(x => x.GetObject<XElement>().Value));
elements.Dump();

This is my solution. I return the first thumbnail image.

// Read the feed
while (await feedReader.Read())
{
    if (feedReader.ElementType == SyndicationElementType.Item)
    {
        // Read the item as generic content
        ISyndicationContent content = await feedReader.ReadContent();

        // Parse the item if needed (unrecognized tags aren't available)
        // Utilize the existing parser
        ISyndicationItem item = parser.CreateItem(content);

        string urlImage = GetThumbailsImage(content, url);
        rssNewsItems.Add(item.ConvertToNewsItem(urlImage));
    }
}

private string GetThumbailsImage(ISyndicationContent content, string source)
{
    // Get <media:thumbnail> field
    ISyndicationContent customElement = content.Fields.FirstOrDefault(f => f.Name == "thumbnail");
    var thimbUrl = customElement.Attributes.FirstOrDefault(a => a.Name == "url");
    return thimbUrl?.Value;
}

You can check our MediaRssSharp for parsing media rss feeds. MediaRssSharp does most of the mrss format parsing for you including optional/non-optional elements.

I added an extension method for the SyndicationItem class. Just create a class called 'ExtensionMethods.cs' in the root of your project and use the code below. Be sure to change the namespace to match that of your project.

using System;

namespace RFAnnouncer
{
    public static class ExtensionMethods
    {
        public static string GetEnclosureUri(this System.ServiceModel.Syndication.SyndicationItem item)
        {
            for (int i = 0; i < item.Links.Count; i++)
            {
                if (item.Links[i].RelationshipType == "enclosure")
                {
                    return item.Links[i].Uri.AbsoluteUri;
                }
            }
            return "";
        }
    }
}
