Modified files:
/php4/pear/XML Render.php
Log:
Added a method to call the HTML and PDF rendering modes(not implemented yet).
Added the parse function which should allow for finer XML parsing.
The XML file contents are now stored in a var available to the entire class.
Added a wrapper around setInputFile() and setInput()
# This class still has a long ways to go, but this is a start.
