RE: in for-each apply-templates doesnot work

This is essentially a grouping problem, where you are only interested in
groups of size 2 or more. As the grouping key is a compound key (it's not
the string-value of a node), take a look at Muenchian grouping, either in
XSLT Programmer's Reference, or at
http://www.jenitennison.com/xslt/grouping.

The two calls on position() above will return the same result, since they
appear in the same template. You haven't shown us what the template rule for
match="row" actually does, but it doesn't make much difference, the above
code is not going to do anything useful.

A more productive approach would be something like

<xsl:variable name="pos2"
select="count(following-sibling::row[...]/preceding-sibling::*)"/>

but I'm not sure what you want to do with the position once you've got it.

That's because you are processing the whitespace text nodes between the
elements, as well as the elements themselves. Get rid of them using
<xsl:strip-space>.

You've lost me here. Fix the other problems first.
