This is a good suggestion, but unfortunately my code uses DOM
extensively, and your example is only useful for an application based
on SAX events. xml.dom.ext.reader.PyExpat creates its own parser, so
that's no help. I tried creating a parser as in your example, but for
the content handler I inherited from xml.dom.ext.Sax2.XmlDomGenerator
instead. I then passed my parser as the parser argument to
xml.dom.ext.reader.Sax2.Reader.__init__() and MyContentHandler as the

Everything parsed fine, but "é" was translated to nothing (no
character in that spot at all) on output. I suspect the skippedEntity
method needs to actually *do* something other than just print that it
is skipping an entity (which it does, so I know my version is being
used), but I am completely ignorant about how to XmlDomGenerator works
internally, and I've never really written SAX-based parsers anyway.
Can you give me a hint?

Thanks for your help,
