Hi, 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! j
