Hi All,
Given the following XML, I've been trying to figure out what XPATH
expression will give me the "position" of a <lineitem> within the
<shipto> that is its grandparent.
To give you an idea of what I'm trying to do...I'm transforming this
XML into XSL-FO; which I will process with FOP to produce a PDF file.
Each <shipto> element with the XML correlates to a new "section"
within the target PDF document. I need to know when I've reached the
last <lineitem> within a <shipto> so I can output some summary
information.
The way I'm approaching this in the XSLT stylesheet is
1. Within the template for <lineitem>, I can use
"count(../..//lineitem)" to give me the total number of <lineitem>'s
within this <shipto>. Then, I want to get the "position" of the
current <lineitem> within the current <shipto>, which I can them
compare against the total to see if this is the last <lineitem>.
I know the XPATH will be "count({somethi ng}) + 1", but I've just not
had any luck determining what "{something }" should be.
Obviously, there could be (and probably is :-) a better (or at least
more elegant) solution to this; but it seems like this will work.
Thanks in advance for any assistance.
Regards,
Mark

Use:
not(following-sibling::lineit em) and not(../following-sibling::invoic e)
When the current node is a "lineitem" the above XPath expression will
evaluate to true() only when this "lineitem" element is the last "grandson"
of its "grandfathe r".

Outstanding! I was thinking that there was a different way to look at
this problem. Thank you very much for the solution and the insight.

Hi there,
if I try to access a table named Position in an Access-Database via
OleDbDataAdapter I get an error. If I rename the table to e.g.
Positions it works.
Any idea how to solve this problem?
(There are about 5.000 databases out there at our customers with a
table in it named Position!)
Thanks a lot for your help
