Your XML has namespaces. See
http://samples.gotdotnet.com/quickstart/howto/doc/Xml/XmlNameSpace.aspx
specifically

"The document also has the default namespace of
http://schemas.microsoft.com/sharepoint/soap/ which we will map to the "ns"
namespace. The reason for needing a prefix for the default namespace in our
XPath query is due to the fact that in XPath, there is no concept of a
default namespace. Instead elements and attributes that have a namespace
require a prefix for matching while unprefixed names in queries can only be
used for elements or that do not have a namespace (i.e. are in the null
namespace). "
