Re: [MonetDB-users] Xquery Standoff Annotation Success Stories? GATE too?

Hi Wouter, I'm a beginner in Xquery, so forgive me if this question seems naive. Using fn:substring(string,start,len), it is possible to write, in pure Xquery, a function that could isolate a substring of a node based on numerical start and end points in another node, right? And from that same information it would be possible to define xquery functions to identify a span as being before, within, or after another, right? If this is more-or-less correct, is the advantage of MonetDB over another xml database primarily the speed boost and not having to write these functions? Or are there other advantages as well? -david
