public class CocoonMarkupLanguage.PreProcessFilter
extends AbstractXMLPipe

Preprocess filter for Cocoon Markup languages. It looks for PI event other that <?xml-logisheet href="..."> for quoting them; It adds creation-date, file-name and file-path attributes to the root Element; And it quotes the PCDATA based by calling the quote method of the programming language.
