Hi,
Might be a lot easier in XSLT 2.0, but I'll leave that for the others.. In XSLT 1.0 this will require a recursive template to split your string into an element structure and after that you have to filter out the duplicates from the element structure. (If anyone has a better idea, tell me!) You can do that with two stylesheets, but also with one if you are prepared to use the node-set extension function. <!-- input xml --> <?xml version="1.0"?> <test>Hello, Hello, Hello, test, dog, cat, cat</test> <!-- first step --> <xsl:template match="*" mode="split-value"> <xsl:param name="value" select="." /> <!-- start with full content string --> <xsl:param name="separator" select="', '"/> <xsl:choose>
<xsl:when test="string-length($value) = 0" /><!-- nothing to do --> <xsl:when test="contains($value, $separator)">
<chunk>
<xsl:value-of select="substring-before($value, $separator)"/>
</chunk>
<!-- look for more chunks -->
<xsl:apply-templates select=".">
<xsl:with-param name="value" select="substring-after($value, $separator)" />
</xsl:apply-templates>
</xsl:when> <!-- last chunk -->
<xsl:otherwise>
<chunk>
<xsl:value-of select="$value"/>
</chunk>
</xsl:otherwise>
</xsl:choose>
</xsl:template><!-- second step --> <!-- build an index that can return all chunks with a certain value -->
<!-- I added the id of the parent to the key, to localize the return values
to only those chunks that have the same parent -->
<xsl:key name="chunks" match="chunk" use="concat(generate-id(parent::*), '-', .)"/><xsl:template match="*[chunk]" mode="unduplicate-and-rejoin"> <xsl:param name="$separator" select="', '" /> <xsl:copy>
<xsl:copy-of select="@*" /> <!-- using generate-id to determine whether the chunk at hand is
the same one as the first returned from the index -->
<xsl:for-each select="chunk[generate-id(.)
= generate-id(key('chunks',
concat(generate-id(parent::*), '-', .))[1])]">
<xsl:value-of select="." />
<xsl:if test="not(position() = last()">
<xsl:value-of select="$separator" />
</xsl:if>
</xsl:for-each>
</xsl:copy>
</xsl:template><!-- the above may contain typos --> Try it with two stylesheets first. If it works, you can try to catch the result from the first step in a variable and pass the variable to xsl:apply-templates with exsl:node-set(..) around it. Hope this helps for now, it is bed time for me... Cheers, Geert Christopher Hansen wrote: 1.0
