cvs: php4 /pear/XML Render.php

metallic Mon Jan 15 16:27:34 2001 EDT 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.
