Re: groupi-by statements?
> So how should I handle this? it depends what rule you want to apply. You must supply a sungle date to the substring function so you could use substring( (mods:originInfo/mods:dateIssued | mods:relatedItem/mods:originInfo/mods:dateIssued | mods:relatedItem/mods:part/mods:date ) ,1,4) which would pick whichever of these three appeared first in document order in the source, or you could use substring( (mods:originInfo/mods:dateIssued , mods:relatedItem/mods:originInfo/mods:dateIssued , mods:relatedItem/mods:part/mods:date ) ,1,4) which would pick the first element in that sequence (as it appears in the stylesheet) which appears in the source. or you could use one of the other 5 permutations of the sequence used in the second version.
