[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: Merging attribute values to unique list
 Hey James,
Here's a solution that can be refactored to be a bit more generalized:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt">
<xsl:template match="/">
<p>See the reading for:
<xsl:variable name="unique-wit-list">
<xsl:call-template name="unique-token-list">
<xsl:with-param name="str">
<xsl:for-each select="//body">
<xsl:text> </xsl:text><xsl:value-of select="@wit"/>
</xsl:for-each>
</xsl:with-param>
</xsl:call-template>
</xsl:variable>
<xsl:for-each select="msxsl:node-set($unique-wit-list)/*">
<xsl:sort select="name()" data-type="text"/>
<a href="foo/a1.xml?wit='{name()}'"><xsl:value-of select="name()"/></a>
</xsl:for-each>
</p>
</xsl:template>
<xsl:template name="unique-token-list">
<xsl:param name="str"/>
<xsl:param name="nl"/>
<xsl:variable name="token"
select="substring-before(concat(normalize-space($str),' '),' ')"/>
<xsl:choose>
<xsl:when test="string-length($token) > 0">
<xsl:call-template name="unique-token-list">
<xsl:with-param name="str" select="substring-after($str,$token)"/>
<xsl:with-param name="nl">
<xsl:copy-of select="msxsl:node-set($nl)/*"/>
<xsl:if test="count(msxsl:node-set($nl)/*[name()=$token]) = 0">
<xsl:element name="{$token}"/>
</xsl:if>
</xsl:with-param>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="msxsl:node-set($nl)"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
I believe the FXSL library has templates that tokenize and remove duplicates
(distinct) ... so, I suspect a less custom solution could be crafted from
that library. I also think the EXSL(?) library has the same capabilities.
Cheers,
Jeff

Subject: Merging attribute values to unique list
Hi there,
This is similar to something I asked months ago, and you'd
think I'd be able to figure it out but... assuming you have
a file like>
<foo id="a1">
<body wit="A B E D">some stuff</body>
<body wit="C A G">some other stuff</body>
</foo>
What I want to produce is a list of links one for each unique witness,
so in this case something like:
<p>See the reading for:
<a href="foo/a1.xml?wit="A">A</a>
<a href="foo/a1.xml?wit="B">B</a>
<a href="foo/a1.xml?wit="C">C</a>
<a href="foo/a1.xml?wit="D">D</a>
<a href="foo/a1.xml?wit="E">E</a>
<a href="foo/a1.xml?wit="G">G</a>
</p>
So, I'm assuming what needs to happen is that I need to somehow produce
a list of each of the tokenized contents of //body/@wit which are
then sorted and made unique. Any suggestions on how to go about this
using Xalan inside cocoon-2.1? I.e. I have some ideas on how to do it
with saxon extensions/xslt 2.0, but not inside cocoon. Any suggestions
appreciated!
-James
