Hi,
I would like to compare elements and determine if any element is out of
alphabetical order, for XPath 1.0. For example,
<Elements>
<Element>AAA</Element>
<Element>BBB</Element>
<Element>CCCC</Element>
</Element>AAAAAA</Element>
</Elements>
I would like this to register that the final element is out of sequence.
I thought about doing this with preceding-sibling, unfortunately, it
turns out that doesn't work for strings. If they are numbers, I can do it.
For example, if I had numbers, such as,
<Elements>
<Element>1</Element>
<Element>2</Element>
<Element>3</Element>
</Element>1</Element>
</Elements>
And I used:
Elements/Element[. < preceding-sibling::node()]
I would get the last element. I suspect I can do this with a template
(manually compare the current node to the preceding-sibling), but I was
wondering if there was a simple way of doing this.
If there isn't, can you please keep the non simple solution (ie the one
where you have to create a template to compare two strings) to yourself
as I would like to have a stab at it myself.
Thanks.
