Re: How do I "merge" nodes based on a common key?

that allows me to group stuff, but how do I "merge" them once grouped?
to rephrase, I still get a line for EACH node in the original data,
rather than one line for all nodes with any given matching @title.
Thanks for your help! - Yossie

I have a xml file I would like to process into a html table. I figure
that xslt is the way to go. The file contains various nodes (results
from load testing) that all share a single attribute, title, that
identifies and links them in groups. See snippet below.
So, I can't figure out some code to process this file and "merge" the
nodes based on the title attribute so I can print each "merged" node
as
a single line in a table. sub-nodes AS well as attributes (though
there
is no overlap in the latter!) should be merged. Then I can use a
<xsl:for-each ..> to process the merged list.
I tried some stuff on my own and it is getting me nowhere (see below).
Any ideas?
