Re: [xsl] with XPath 1.0, select all following sibling elements of name "foo" up to the first non-"foo" element

["Dimitre Novatchev dnovatchev@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

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>&#10;</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>&#10;=======================</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"/>
=======================
