hi,
The search term ($target1) may appear within a <p>, within a <note>,
or within a <p> that is within a <note>. If it occurs anywhere within a
note, then I need not only the note but the paragraph in which it
resides. Which further muddies the water because if a paragraph
contains the search term and that same paragraph also contains a <note>
that contains the search term, I still need to output that paragraph
only once.
The problem is caused by this template:
<xsl:template match="text()" mode="search">
<xsl:param name="term" select="''"/>
<xsl:param name="element" select="''"/>
<xsl:choose>
<xsl:when test="contains(.,$term)">
<xsl:for-each select="ancestor::p[not(parent::note)][1]">
<xsl:apply-templates/>
<hr/><br/>
</xsl:for-each>
</xsl:when>
<xsl:otherwise/>
</xsl:choose>
</xsl:template>
It makes a textual copy of its container for each and every text node that
contains the searched text.
You could add an expression to the 'xsl:when' that is only true at the
first match:
<xsl:template match="text()" mode="search">
<xsl:param name="term" select="''"/>
<xsl:param name="element" select="''"/>
<xsl:choose>
<xsl:when test="contains(.,$term) and
generate-id()=generate-id(ancestor::p[not(parent::note)][1]//text()[contains(.,$term)])">
<xsl:apply-templates
select="ancestor::p[not(parent::note)][1]"/>
<hr/><br/>
</xsl:when>
<xsl:otherwise/>
</xsl:choose>
</xsl:template>
You might also avoid the duplication by copying at the top rather than
after diving in the tree. e.g.:
<xsl:template match="/">
<div>
<xsl:for-each
select="/*/*[local-name()=document('')/*/xsl:variable[(_at_)name='select-elements']/item][contains(.,$target1)]">
<xsl:copy-of select="."/>
<hr/>
</xsl:for-each>
</div>
</xsl:template>
