Here is one working solution, using a key :half the way":
<xsl:stylesheet version="1.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform";>
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:key name="kPrecedingFoo" match="foo"
use="generate-id(following-sibling::*[not(self::foo)][1])"/>
<xsl:template match="/*/*">
Results for: <xsl:copy-of select="."/>
<xsl:text> </xsl:text>
<xsl:copy-of select=
"
*key('kPrecedingFoo',
generate-id(following-sibling::*[not(self::foo)][1]))
[current()[self::foo] and not( count(current()/preceding-sibling::foo | .)
= count(current()/preceding-sibling::foo ) )]*
"/>
<xsl:text> =======================</xsl:text>
</xsl:template>
</xsl:stylesheet>
When applied on this XML document, it produces (what I believe based on my
understanding of the question) the correct results:
Results for: <bar ind="1"/>
=======================
Results for: <foo ind="1"/>
<foo ind="1"/>
<foo ind="2"/>
<foo ind="3"/>
=======================
Results for: <foo ind="2"/>
<foo ind="2"/>
<foo ind="3"/>
=======================
Results for: <foo ind="3"/>
<foo ind="3"/>
=======================
Results for: <bar ind="2"/>
=======================
Results for: <foo ind="4"/>
<foo ind="4"/>
=======================

Hello,
Just eyeballing this, Dmitry, I'm not convinced it would work if
Wolfhart was sitting at a <foo> at the time he made his request, in
which case the <foo> he was at would incorrectly be included.
Granted the original requirement is underspecified in this regard, so
perhaps my observation is irrelevant. I'm not trying to nit-pick but I
discounted the use of keys because of the arbitrary starting point for
evaluation.
Wolfhart, am I being too pedantic here?
I have never used <xsl:key>, so I cannot evaluate Dimitre's solution.
But yes, the current element may be a <foo> in my case. Sorry for not
making that clear in my original request!
