Re: concat all items in a sequence

  contains(string-join(for $i in elem return $i, ''), val)

  Is there a better way?
 

you can (always) write 
for $i in elem return $i
as
elem

so if you want to concat you could do


contains(string-join(elem, ''), val)

or (depending on what you want to do if val is a substring of the
concatenation but not of any value, you may want



true()=elem/contains(./val)
