 The difficulty may lie in the fact that MSXML is playing fast and loose with "node()". Keep in mind that "node()" and element are not synonymous. "node()" includes text-only nodes which do not have names, local or otherwise. Try replacing all instances of "following-sibling::node()[1]" with "preceding-sibling::element[1]" in your stylesheet and let us know if this isn't more to your liking.

Subject: Collapsing run-on tag chains not working in saxon or xalan
Dear All,
With the following xml and xsl, the Microsoft msxmldom 4 is producing
the expected output, but xalan 2.4, 2.6, and saxon 6.5.3 are not: they
all produce
the same, unexpected output.
The purpose of this code is to collapse run-on chains like
<ilink>foo</link><link id="1234">bar</link> into a single tag
<link>foo bar<id id="1234"/>
</ilink>. The xsl will also collapse run-on chains of b, i, sup, sub,
and similar tags.
Can anyone explain to me whether xalan and saxon just have a bug, and
preferably how to get xalan and/or saxon to transform the way msxml4
does here
(which I believe is correct)?
TMIA,
Richard Bondi
