(a) get rid of the <p> and <sp> start and end tags, which contribute nothing
to the output
(b) the <lb/> elements are now all on the same level, so you can use
xsl:for-each-group group-starting-with="lb"
Step (a) is essentially
<xsl:variable name="temp">
<xsl:apply-templates select="/" mode="step-a"/>
</xsl:variable>
<xsl:template match="*" mode="step-a">
<xsl:copy><xsl:apply-templates/></xsl:copy>
</xsl:template>
<xsl:template match="p|sp" mode="step-a">
<xsl:apply-templates/>
</xsl:template>
Step (b) is
<xsl:for-each-group select="$temp/*" group-starting-with="lb">
<fo:block><xsl:apply-templates select="current-group"
mode="step-b"/></fo:block>
</xsl:for-each-group>
<xsl:template match="pb" mode="step-b"/>
<xsl:template match="speaker" mode="step-b">
<fo:inline><xsl:value-of select="."/></fo:inline>
</xsl:template>
Now it might be that I have made incorrect inferences from your small sample
dataset. If so, you will have to try and explain the problem in more detail.
