Wikimedia provides database dumps of all of its public wikis. These contain XML text for all articles (with the exception of deleted pages) with past revisions. These do not contain uploaded images.
Dumps for the English-language Wikivoyage are available at http://dumps.wikimedia.org/enwikivoyage
In particular, the wikicode for all current mainspace articles (without past revisions) is this file, it is under 100 MB.
The English-language database was imported to the Wikimedia Foundation servers on Nov 10, 2012. The WMF dump dated 2012-Nov-18 is therefore the first to contain valid data.
Listings data is also available at http://wvpoi.batalex.ru as CSV, XML, GPX, OBF, SQL.
That makes it easy to integrate Wikivoyage listings in your app/website.
