Deserialize Attribute with a Namespace

[Jon]

I have an xml document like so...

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:ng="http://newsgator.com/schema/extensions">
<channel>
<title></title>
<link></link>
<description></description>

...

</channel>
</rss>

What .NET XmlAttribute properties do I need to use in order to
deserialize the namespace value?

I tried this and a bunch of other options, but nothing seems to work.

[XmlAttribute("ng", "http://newsgator.com/schema/extensions")]
public string XmlnsNg {
get {
return _xmlnsNg;
}
set {
_xmlnsNg = value;
}
}
Thanks in advance!

The namespace declaration is not the same as an attribute, even though they
are declared in the same way (although I think I stated it incorrectly in a
different message). The namespace itself would be applied to the "RSS"
class as part of the XmlRootAttribute decl.

BTW: Hint for figuring this stuff out -xsd.exe. You can generate a schema
for the XML (VS.Net's XML menu does that) and then generate a class for the
schema (xsd MySchema.xsd /classes), which will show you how the runtime
expects the attributes to be applied.

Thanks Keith.

I'm trying that. Here's where I'm at.

I generated the xsd:

When I run XSD.exe I get this:

Warning: Schema could not be validated. Class generation may fail or

Error: Error generating classes for schema ''.
- The element 'http://newsgator.com/schema/extensions:mceImage' is

If you would like more help, please type "xsd /?".
Any ideas?

I got this to work, but it doesn't generate the declarations for the
namespaces and doesn't create a property for them like it does for
other attributes.

I think I'm okay. I will just not render the attributes as well.
