The following is an outline of a general way to process groups of nodes
delimited by a specific element. This transformation:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:apply-templates select="/*/p/pb"/>
</xsl:template>
<xsl:template match="p/pb">
<xsl:element name="group{position()}">
<xsl:apply-templates
select="preceding-sibling::node()[not(self::pb)]
[generate-id(following-sibling::pb)
=
generate-id(current())
]"/>
</xsl:element>
<xsl:if test="position() = last()">
<xsl:element name="group{position() + 1}">
<xsl:apply-templates select="following-sibling::node()"/>
</xsl:element>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
when applied on this source.xml:
<html>
<p>some text1 some text1
<pb/>more text2 more text2
<pb/>more text3 more text3
</p>
</html>
produces:
<group1>some text1 some text1
</group1>
<group2>more text2 more text2
</group2>
<group3>more text3 more text3
</group3>
As we see, all nodes between two consecutive markers will be processed
as a group.
