Dear Jason,
I set up a database in BaseX with the Wikipedia articles dump (all 25 GB of it). I'm able to access individual articles though the treemap display (by clicking on them), but I get null responses for every xpath query run, even really basic stuff like "//title." I'm sorry if this is a very obvious question; I'm a beginner to XML databases. Any ideas as the problem, or what to do to find out more? Thanks!
You need to specify the namespace of the Wikipedia document in the prolog of your query: declare default element namespace "http://www.mediawiki.org/xml/export-0.3/"; //title If you prefer short expressions, just add a prefix wildcard in front of the tag names: //*:title Hope this helps, Christian ___________________________ Christian Gruen Universitaet Konstanz Department of Computer & Information Science D-78457 Konstanz, Germany Tel: +49 (0)7531/88-4449, Fax: +49 (0)7531/88-3577 http://www.inf.uni-konstanz.de/~gruen
