I have a class like this:
public static class MyFeedExtensions
{
private readonly static XNamespace _namespace = XNamespace.Get(@"http://mynamespace");
public static XElement MyElement(string value)
{
return new XElement(_namespace + "MyElement", value);
}
}
I'm using it to generate an Atom Feed with custom Extensions:
var feed = new SyndicationFeed();
feed.ElementExtensions.Add(MyFeedExtensions.MyElement("Testing!"));
This works fine, except that the feed adds my namespace to the element:
<feed xmlns="http://www.w3.org/2005/Atom">
<title type="text">Hello World!</title>
<id>00000000-0000-0000-0000-000000000000</id>
<updated>2011-03-01T01:00:53Z</updated>
<MyElement xmlns="http://mynamespace">Testing!</MyElement>
</feed>
Is there a way to register a namespace with the feed instead, to get an output like this?
<feed xmlns="http://www.w3.org/2005/Atom" xmlns:my="http://mynamespace">
<title type="text">Hello World!</title>
<id>00000000-0000-0000-0000-000000000000</id>
<updated>2011-03-01T01:00:53Z</updated>
<my:MyElement>Testing!</my:MyElement>
</feed>
Ideally, I would like this also to work when I have SyndicationItems with ElementExtensions, as the feed should know about all the various namespaces.
(Edit: This is purely to reduce the Size of the XML and to make it easier to read for humans)
Found the answer in this question and adapted it:
feed.AttributeExtensions.Add(
new XmlQualifiedName("my",XNamespace.Xmlns.ToString()),
MyFeedExtensions.Namespace.ToString());
Basically: Register a xmlns:my
Attribute with the feed, it will pick up the namespace automatically on the elements even if they are added to a SyndicationItem
within the feed.
Obscure, but neat!
