Here's another problem:
<xsl:for-each-group select="current-group()" group-by="substring(mods:originInfo/mods:dateIssued,1,4)"> One of the good things about the data in question is it's recursive. It's also a problem in this context. The year that is critical to this processing can be represented like: mods:originInfo/mods:dateIssued (as above) mods:relatedItem/mods:originInfo/mods:dateIssued (the date issued for a book, where the main record is a chapter) mods:relatedItem/mods:part/mods:date (the sort of date you may have with a journal article; associated with the issue) If I have more than one of these expressions in my group-by statement, I get a "A sequence of more than one item is not allowed as the first argument of substring()" error. So how should I handle this? Should I define a function -- called, say, bib:year -- that I can call like so? <xsl:for-each-group select="current-group()" group-by="bib:year()"> Bruce
