Question

I am currently trying to deserialize some XML in the following format:

<content:encoded>![CDATA[...

And I have an object which has a property which looks like:

[XmlElementAttribute("content")]
public string Content { get; set; }

However despite the XML always having a value the property in the code is always null?

Answer 1

content is a namespace in your example. Your element name is actually encoded so you will need to use the attribute marking your property as such:

[XmlElement("encoded", Namespace => "custom-content-namespace")]
public string Content { get; set; }

Note that you will need to declare the namespace in your containing XML:

<content:encoded xmlns:content="custom-content-namespace">![CDATA[...

This also means any child nodes would be prefixed with the same namespace. Not so much an issue for CDATA content, but just in case you have other elements you are trying to deserialize.
