Given XSLT 2.0, you can select two elements $a and $b, and then the number
of elements between these two is
count($b/preceding-sibling::*) - count($b/preceding-sibling::*) - 1
This is probably more efficient than
count(*[. >> $a and $b >> .])
but you can use that if it's more convenient.
(I'm assuming that by "between" you mean "between and on the same level".
That is, the number of elements between <a/> and <b/> in
<a/><node><child/></node><b/>
is one.)

Subject: [xsl] counting nodes before a certain node
Hi
How do I count nodes up to a certain point in XSLT?
Example:
My xml file looks like this:
<books>
<book>
<title>First title</book>
</book>
<notes>The following books talk about history.</notes>
<notes>For further information please log on to </notes>
<notes>Thank you for choosing.. </notes> <book>
<title>Abraham Lincoln </title> </book>
<authors>
sample data
</authors>
<notes>Please call... </notes>
<notes>Copyright Information </notes>
<book>
sample data
</book>
</books>
In my XSLT file, I want to count all <notes> just before the
second <book> element but immediately after the first book
element or just after <authors>.
How do I count all the notes elements here?
