Dear Mark, I'm sorry to tell you that the boundary matcher \b is not officially supported by XQuery [1,2]; this is why it is not supported anymore by the latest version of BaseX. If you want to have this feature provided in XQuery 3.0 or a future version, you are invited to submit a small feature request in the W3 Issue Tracker [3].
All the best, Christian [1] http://www.w3.org/TR/xpath-functions/#regex-syntax [2] http://www.w3.org/TR/xmlschema-2/#regexs [3] https://www.w3.org/Bugs/Public/ On Sat, Jan 7, 2012 at 9:37 PM, Mark Boon <tesujisoftw...@gmail.com> wrote: > It's been a while since I did anything with BaseX.
