xml.sax.xmlreader.InputSource.setByteStream()

InputSource.setByteStream(bytefile)

Set the byte stream (a binary file) for this input source.

The SAX parser will ignore this if there is also a character stream specified, but it will use a byte stream in preference to opening a URI connection itself.

If the application knows the character encoding of the byte stream, it should set it with the setEncoding method.
