where need condition below.
there should `footnote` following `page` , there should no `page` between `page` , `footnote` in simple, taking above example, there 2 page, ignoring other tags , considering page structure looks below.
page num='44' page num='45' footnote here want page num='45' captured , leave page num='44' since page num='44' followed page not directly footnote, pretty confusing, please let me know how can this.
the demo can found here
thanks
when match page can check whether next footnote has preceding page current page. if it's not, don't print out processing instruction since it's page without footnote.
<xsl:template match="page" mode="footnote"> <xsl:if test="following::footnote[1][preceding::page[1]/@num = current()/@num]"> <xsl:processing-instruction name="pb"> <xsl:text>label='</xsl:text> <xsl:value-of select="./@num"/> <xsl:text>'</xsl:text> <xsl:text>?</xsl:text> </xsl:processing-instruction> </xsl:if> </xsl:template>
