Thanks for your reply!

For me, this does not work because the nodes are in a variable, that I
selected from another node-set. And my <foo> nodes do not have a
common parent.
I did something like this: <xsl:variable name=3D"fie" select=3D"root/foo
[..some predicate here....].
Maybe I can build a new node set with a root node with the _selected_
foos beneath? And then do the preceding-sibling trick?

The Muenchian approach is also difficult (impossible?) to apply,
because xsl:key is a top-level node only.

Again, thanks very much for your help!
