XPathNavigator.SelectChildren(XPathNodeType.Attrib ute) doesn't work?

[Keith Patrick]

I'm converting over from using XmlNodes (specifically ConfigXmlNode, but the
API uses XmlNode) to IXPathNavigable in some methods I have, but I'm finding
in the process, that I can't seem to get the attributes. If I have some
XML:

<ApplicationConfiguration Test="Blahblah"
AnotherAttr="asdfasd">

And I have the code:

XPathNavigator navigator = node.CreateNavigator();
XPathNodeIterator child =
navigator.SelectChildren(XPathNodeType.Attribute);

foreach (Object child in
navigator.SelectChildren(XPathNodeType.Attribute))
{
System.Diagnostics.Debug.WriteLine(child.ToString( ));
}

But the child count is always 0. If I change to XPathNodeType.All, I will
enumerate through the child elements, but again, the attributes don't show
up. Is this correct behavior, a bug, or am I misusing IXPathNavigable?

Attribute nodes are not children of an element node, neither in the DOM
data model nor in the XPath data model. Use MoveToFirstAttribute and
MoveToNextAttribute if you want to iterate over attributes with an
XPathNavigator.
