a cow on ice... :)

Don't worry too much about push and pull - for grouping you have to
use pull - and for-each-group is excellent (like most things in XSLT
once you 'get' them)

Here's an example using for-each-group with group-ending-with:

<xsl:stylesheet
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="2.0">

    <xsl:output indent="yes"/>

    <xsl:variable name="input">
        <div>
            <p>p</p>
            <h1></h1>
            <h2></h2>
            <p>p2</p>
        </div>
    </xsl:variable>

    <xsl:template match="/">
        <xsl:for-each-group select="$input/div/*" group-ending-with="h1|h2">
            <group>
                <xsl:copy-of select="current-group()"/>
            </group>
        </xsl:for-each-group>
    </xsl:template>

</xsl:stylesheet>

It generates this output:

<group>
   <p>p</p>
   <h1/>
</group>
<group>
   <h2/>
</group>
<group>
   <p>p2</p>
</group>

Is that what you were after?  If not, modify the input and and
required output and post back.
