Re: [xsl] eliminating multiple repeated tags in my XML

[David Carlisle <davidc@xxxxxxxxx>]

You are making the templat ematch on related-article and then trying to
group all the related-article children of this (related-artcicle)
element, but there are none, so basically you just want to change to
match article-meta instead.  Also i changed your input example to be
well formed and have some elements other than original-article types at
this level just to show that these are not grouped, whereas the original
articles are.


I also removed the character map stuff as I didn't have it to hand at
the right realtive location and they are not relevant to the problem
(although actually they began life on this machine, if as I guess they
are my map files you are using?)
