I'm trying to figure out a way to sort by one of multiple elements, with descending priority. You create a select expression that chooses the element you want in the presence or absence of other items. I'm working with a TEI bibliography, and there's no single element that all the entries have. Ideally, I'd like to sort by monogr/author; but when that's not possible, by analytic/author; if not that, monogr/editor; then monogr/title; and so on down the line. In XSLT 2.0, choose the first item in a sequence of many items, priority indicated by the order of your sequence: <xsl:sort select=" ( monogr/author, analytic/author, monogr/editor, monogr/title )[1]"/> In XSLT 1.0 you might do something along the lines of: <xsl:sort select=" monogr/author | self::*[not(monogr/author)]/analytic/author | self::*[not(monogr/author | analytic/author)]/monogr/editor | self::*[not(monogr/author | analytic/author | monogr/editor)]/monogr/title"/> I hope this helps. . . . . . . . . . .
