I'm reading in an XML file with might be in either a 'new' format which
defines a default namespace, like this :

<rootElement xmlns:some-url>
<otherstuff/>
</rootElement>

.... or might be in an older format without a default namespace :

<rootElement>
<differentstuff>
</rootElement>

What's the best way of using an XPathNavigator to find out whether the xmlns
is present ?

Thanks,

Steve

As for the current node, you can check whether the Prefix property is
empty while the NamespaceUri points to a URL.
You could also try to navigate the namespace nodes with
MoveToFirstNamespace/MoveToNamespace/MoveToNextNamespace.

In general you need to be aware that a default namespace declaration can
occur on any element and not only on the root element.
