As part of the Wikidata implementation we will have a shot at importing and exporting data using formats like XML. There are already some people interesting in helping out with this. Exporting the current wiki data in XML could be part of that effort, It would be a good thing to combine things as we propably do not want to publish XML in too many ways,
XML by itself doesn't provide any structure. What sort of XML schema is used on WikiData's import/export or which method you use to pull the old freeform text entries in the first place are relatively minor details; the hard part is making structure out of the text, and there's not really a good generation solution. That's going to be very specific to the task (converting Wiktionary to a structured database).
