If there's a common helper class that people can use as a base, then filters can be very light anyway (the base class should just pass through all events unmodified and provide access to registered handlers). Here's a filter that renames all "foo" elements to "bar": import org.xml.sax.AttributeList; import org.xml.sax2.helpers.SAXFilter; public class FooFilter extends SAXFilter { public void startElement (String name, AttributeList atts) { if (name.equals("foo")) { getDocumentHandler().startElement("bar", atts); } else { getDocumentHandler().startElement(name, atts); } } public void endElement (String name) { if (name.equals("foo")) { getDocumentHandler().endElement("bar"); } else { getDocumentHandler().endElement(name); } } } > I also didn't think a lot of folks would be filtering DTD events, > that is unless they got extended. If people are using DTD events at all, they'll probably want to filter them (fiddling with notations, etc.). Likewise with lexical events.
