There is another option: parse the document only once using
expat. More precisely, register a set of handlers with expat that
feeds both the trex parsing, and a DOM builder
(i.e. xml.dom.ext.readers.PyExpat); alternatively, feed both pytrex
and expatreader, and use the resulting SAX events to build a DOM tree.
