 Maybe I'm missing the obvious, but I've Googled forever and am still lost. I want to search a document for every occurrence of a particular word and output each paragraph that includes the search term. My code works fine except that if the search term appears in one paragraph 3 times, then I get that paragraph three times in the output. I do not want to repeat same paragraph. I'm not sure what I should be looking for. I know a little about how to de-duplicate using keys, but I don't see how that can work in this case. And I know almost nothing about recursion. Is that what is required here? Any pointers would be greatly appreciated. Thanks, Susan The xml looks like this (I do hope this makes sense): <p> ...may contain text only or a mixture of text and other elements... </p> <p>...may contain... <note>a note with text only</note> </p> <p>...may also contain... <note>no paragraph tags here, just text<p>2nd paragraph of note</p><p>3rd paragraph of note</p></note> ...more text... </p> The search term ($target1) may appear within a <p>, within a <note>, or within a <p> that is within a <note>. If it occurs anywhere within a note, then I need not only the note but the paragraph in which it resides. Which further muddies the water because if a paragraph contains the search term and that same paragraph also contains a <note> that contains the search term, I still need to output that paragraph only once. My stylesheet (stripped of all the formatting stuff) looks like: ***** <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:variable name="target1"> <item>find-this-word</item> </xsl:variable> <xsl:variable name="select-elements"> <item>p</item> </xsl:variable> <xsl:template match="/"> <xsl:apply-templates select="/" mode="search"> <xsl:with-param name="term" select="$target1"/> <xsl:with-param name="element" select="document('')/*/xsl:variable[@name='select-elements']/item"/> </xsl:apply-templates> </xsl:template> <xsl:template match="/" mode="search">
<xsl:param name="term" select="''"/>
<xsl:param name="element" select="''"/>
<div>
<xsl:apply-templates select="@*|node()" mode="search">
<xsl:with-param name="term" select="$term"/>
<xsl:with-param name="element" select="$element"/>
</xsl:apply-templates>
</div>
</xsl:template><xsl:template match="@*|node()" mode="search">
<xsl:param name="term" select="''"/>
<xsl:param name="element" select="''"/>
<xsl:copy>
<xsl:apply-templates select="@*|node()" mode="search">
<xsl:with-param name="term" select="$term"/>
<xsl:with-param name="element" select="$element"/>
</xsl:apply-templates>
</xsl:copy>
</xsl: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> *****
