Hi,[...]
I would like to compare elements and determine if any element is out of
alphabetical order, for XPath 1.0. For example,
Although there isn't an XPath 1.0 operator for string comparison, XSLT 1.0 still has to be able to compare strings because of <xsl:sort>.
So you could apply-templates or for-each on the list, using <xsl:sort> to sort alphabetically, and then flag any element where its position() != count(preceding-sibling::*) + 1.
I'm not certain that it's any prettier. Because you are using
apply-templates/for-each (which conceptually does its items in parallel),
you can't stop after flagging the first out-of-order item. You are also
at the mercy of your locale as to what "alphabetical order" is. That may
or may not matter to you.
