Fixed xml-format issue on Windows

- Fixed issue where CDATA detection mechanism (hack) failed to work correctly
  on Windows due to a difference in behavior between Unix and Windows.  On
  Windows the source file (the 'base' attribute) is returned as URL-like
  format by lxml rather than an absolute path (string) as is done on
  Unix.  Since only files are supported, the scheme prefix is removed.
- Disable one unittest that doesn't play well with NT, I think because of EOL
  issues.  Not a priority right now.
