[Qt-interest] Problems with XML and XQuery

[Esdras Beleza]

doc($data) was wrong, since $data is not a filepath. I changed my query to

query.setQuery("$data/lfm/artist/name");

and now I obtaining this error:

Error XPTY0019 in file:///home/esdras/dev/player/Player, at line 1, column
1: Required type is node(), but xs:string was found.
