On Thu, 10 Sep 2009 09:03:14 -0700 I wrote: < <xsl:sequence select=" < if (empty($a) and empty($b)) < then 0 < else if ($a[1] ne $b[1]) < then $pos < else < f:mismatch-position(remove($a, 1), remove($b, 1), $pos + 1)" /> Meanwhile I'm pondering the difference between else if ($a[1] ne $b[1]) and else if (not($a[1] eq $b[1])) When one of $a or $b are empty... I guess I better dig up the XPath spec and refresh my understanding of effective boolean values. Jim - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - James A.
