Re: [xsl] General algorithm for finding nodes between PIs

["Michael Kay mike@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I think this could be simplified:

> <xsl:template match="*[processing-instruction('Fm')[starts-with(.,
'Condstart')]]">
> 		<xsl:for-each-group select="node()"
group-starting-with="processing-instruction('Fm')[starts-with(.,
'Condstart')]">
> 			<xsl:if test="self::processing-instruction('Fm')[starts-with(.,
'Condstart')]">
> 				<group name="{.}">
> 					<xsl:variable name="pi-end-name" select="replace(., 'Condstart',
'Condend')"/>
> 					<xsl:variable name="end"
select="following-sibling::processing-instruction('Fm')[. =
$pi-end-name][1]">
> 					<xsl:copy-of select="current-group()[. &lt;&lt; $end]"/>
> 				</group>
> 			</xsl:if>
> 		</xsl:for-each-group>
> 		<xsl:apply-templates/>
> 	</xsl:template>
