nothing obviously wrong here except that use of NoBufferingInputStream
may degrade perfromance :-)

did you look on src/java/samples/MyXmlPullApp.java in XPP3 distribution.

for example running it on build.xml produces this (make sure you get the same parser implementation
class!):

     java MyXmlPullApp build.xml
     parser implementation class is class org.xmlpull.mxp1.MXParserCachingStrings
     Parsing file: build.xml
     Start document
     Start element: project
     Characters:    "\n\n  \n  \n\n  "
     Start element: property
     End element: property
     Characters:    "\n\n  "
     Start element: property
     End element: property
     Characters:    "\n  "
     ...

all what this sample does to set input is to call
   xpp.setInput ( new FileReader ( args [i] ) ).

then i modified sample to use:
      xpp.setInput ( new InputStreamReader( new FileInputStream ( args [i] ) ) );
and it worked also fine.

finally i have used new method setInput that takes input stream directly:
  xpp.setInput ( new FileInputStream ( args [i] ), "UTF8"  );
and that also worked :-)

please make sure that you use the latast XPP3 version 1.0.8a from
    http://www.extreme.indiana.edu/xgws/xsoap/xpp/download/

using StringReader is discouraged as it will prevent from doing
real incremental (streaming) file parsing.

hope it helps (let me know if you still have problem),

thanks.
