You don't show the code that you're using, but my guess would be that
when you use selectSingleNode(), you're not including a namespace
prefix on the element name. Try using the following code:

  // Use XPath rather than XSL Patterns to select your nodes
  yourDOM.setProperty("SelectionLanguage", "XPath");

  // Declare the namespace you want to use with a prefix
  yourDOM.setProperty("SelectionNamespaces", "xmlns:xyz='xyz'");
  // Use the prefix when you refer to the element you want to select
  node = yourDOM.selectSingleNode("/xyz:Environment");

When you use XPath, if you specify an element name without a prefix as
in "/Environment" then you will only select elements with that local
name in *no namespace*. If you want to select elements that are in a
namespace (as your <Environment> element is) then you need to declare
that namespace with a prefix and use that prefix to refer to the
