Hi Tom,
(Earlier today Michael Kay answered a message that involved
recommending this library: http://www.functx.com/functx/ ... so I had
a quick look at functx and it is fresh in my mind.)
These functions are not exactly like your fantasy pseudo code... but I
think there some useful functions that may have help solve your
problem....
For example:
http://www.xsltfunctions.com/xsl/functx_sequence-node-equal.html
http://www.xsltfunctions.com/xsl/functx_sequence-node-equal-any-order.html
If you peruse the functions, I think you'll find many other
interesting/related functions that you may be able to leverage.
(Note: I found the download link difficult to find on the page...
Hint: It's at the top of the page.)

Hi,
I'd like to be able to determine which element is "closer", in terms of
document order, to a given element. eg, given two structures containing
siblings:
<a>
<b>
<c>
and
<b>
<a>
<c>
I'd like to detect that the second structure is "out of order". In my fantasy
pseudo code, I might express the constraint as:
//c[positionEX(preceding::a[1]) > positionEX(preceding::b[1])]
Where my fantasy positionEX() function returns the absolute position of the
argument in the document.
Am I missing something, or is implementing this operation in real xpath/xslt
much more difficult than it seems it should be?
Thanks in advance for any help...
