No, definitely not.

I didn't test this, but something like this should do it:

// Read the htmlcleaner into a 'template' object
// This part needs to be executed just once
var configfile = "/path/to/htmlcleaner.xml";
var factory = new Packages.org.outerj.daisy.htmlcleaner.HtmlCleanerFactory();
var is = new Packages.org.xml.sax.InputSource(configfile);
var template = factory.buildTemplate(is);

// For each clean operator, do this
var htmlcleaner = template.newHtmlCleaner();
var result = htmlcleaner.cleanToByteArray("<html>foo</html>");

Let me know if it works, then I'll add it to the samples.
