> We used to work with a pre-release version of exist 1.5 where the function util:node-xpath(). Now on exist 2.1 we are seeing something new in this function. What we want to do is extract xml from a file at a given xpath expression so we look for:
> 	doc($somedoc)//*[util:node-xpath(.)=$somexpath]
> 
> Under exist 2.1 this fails because there is some extra non-printable in the path the node-path() returns some how, but only when there's a @schemaLocation on that node. Adding normalize-space() seems to circumvent.
