[basex-talk] Xquery for multiple files

Hello all, I am not sure if this can be done in XQuery, and if BaseX makes it possible, but I am trying to query all the files under a directory. This directory is copied through webdav. For example, I need to get all the files that have root <article>. Searching for how to do this, I came across this post, that shows how to do something similar with marklogic http://stackoverflow.com/questions/19243253/search-and-load-all-xml-files-in... How to do this in BaseX if possible ?? Thank you.
