  If you don't like the defaults I/O interface, override with your own:

  What is an ANSI XML File ? Never heard of this ?

  You seems horribly confused mixing properties of the filename name and the
content of the file. Or I just can't understand your question.

  Where on earth did you see "ANSI XML" defined ?
libxml will parse any XML file in one of the encodings whose support is
mandatory per the XML spec. Whether it comes from a file, a pipe or an
in-memory buffer.
  Please:
    1/ read the spec
       http://www.w3.org/TR/REC-xml
    2/ read libxml doc and API description
       http://xmlsoft.org/
       http://xmlsoft.org/html/libxml-lib.html
 
  Then try to rephase your question using standard terminology, I can't
make guesses on what you're trying to explain.
