Stripping Namespace -- dotnet xml

A buffer containing an xml document with a default namespace is fed to
an XmlValidatingReader. The reader loads a schema targeting the same
namespace, and is passed to an XslTransform. Because XslTransform does
not implement XSLT 2.0, I cannot target the default namespace. The xslt
is long and complex, prefixing all the xpaths is out of the question.
The only solution I can come up with is to strip ' xmlns="urn:foo"' from
the root element of the output of the XmlValidatingReader before it gets
to the XPathNavigator which feeds it to the XslTransform. What is the
easiest way to do this?

Well, you can implement custom XmlReader, which delegates all calls to a
parent XmlReader (XmlValidatingReader in your chain), while always
exposes empty string in NamespaceUri property. Something like:

public class NamespaceUnawareXmlReader : XmlReader {
private XmlReader parent;

public NamespaceUnawareXmlReader(XmlReader parent) {
this.parent = parent;
}

//XmlReader overrides
public override string Name { get { return parent.Name; } }
//do the rest this way
...

//No namespaces (should it be null or empty string - don't remember ?)
public override string NamespaceURI { get { return ""; }}
public override string Prefix { get { return ""; }}
}
