xslt 1.0 - I've a set of nodes, for which I want
a. to replace some values (most will not change), then
b. eliminate the duplicates and sort them.
..............................................................................
The text nodes represent URI's and are then used to
create html links. So far I was only able to write in
2 different task what should be done in one:
One simple way to do this:
The following transformation:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:key name="kb" match="b[not(. = ../../e2/f/@c)]"
use="."/>
<xsl:key name="kb" match="@b1"
use="../../../e1/b[. = current()/../@c]"/>
<xsl:key name="kDist" match="b | @b1"
use="."/>
<xsl:template match="/">
<e3>
<xsl:for-each select=
"key('kb', */e1/b)[generate-id()
=
generate-id(key('kDist', .)[1])
]">
<xsl:sort/>
<b2><xsl:value-of select="."/></b2>
</xsl:for-each>
</e3>
</xsl:template>
</xsl:stylesheet>
when applied on the provided source xml document:
<a>
<e1>
<b>abc</b>
<b>abd</b>
<b>abe</b>
<b>abf</b>
<b>abg</b>
<b>abh</b>
<b>abd</b>
</e1>
<e2>
<f c="abe" b1="abc"/>
<f c="abf" b1="abj"/>
<f c="abg" b1="abi"/>
<f c="abh" b1="abi"/>
</e2>
</a>
produces the wanted result:
<e3>
<b2>abc</b2>
<b2>abd</b2>
<b2>abi</b2>
<b2>abj</b2>
</e3>
Hope this helped.

Truly great madness cannot be achieved without significant intelligence.

Hi list,
xslt 1.0 - I've a set of nodes, for which I want

b. eliminate the duplicates and sort them.
Sample input xml:
<?xml version="1.0" encoding="UTF-8" ?>
<a>
<e1>
<b>abc</b>
<b>abd</b>
<b>abe</b>
<b>abf</b>
<b>abg</b>
<b>abh</b>
<b>abd</b>
</e1>
<e2>
<f c="abe" b1="abc"/>
<f c="abf" b1="abj"/>
<f c="abg" b1="abi"/>
<f c="abh" b1="abi"/>
</e2>
</a>
The input table _e1_ will be transformed using _f_ to
<e1>
<b>abc</b>
<b>abd</b>
<b>abc</b>
<b>abj</b>
<b>abi</b>
<b>abi</b>
<b>abd</b>
</e1>
and finally should become
=== what I would like to have ===
<e3>
<b2>abc</b2>
<b2>abd</b2>
<b2>abi</b2>
<b2>abj</b2>
</e3>

<xsl:template match="node() | @*">
<xsl:copy>
<xsl:apply-templates select="node() | @*"/>
</xsl:copy>
</xsl:template>
<xsl:key name="dupl" match="b" use="."/>
<xsl:template match="e1">
<xsl:copy>
<xsl:for-each
select="b[count(self::b|key('dupl',self::b)[1])=1]">
<xsl:sort select="."/>

</xsl:for-each>
</xsl:copy>

<xsl:template match="e2"/>
<xsl:template match="e3"/>
<xsl:template match="node() | @*" mode="trans">
<xsl:copy>
<xsl:apply-templates select="node() | @*" mode="trans"/>
</xsl:copy>
</xsl:template>
<xsl:key name="trans" match="f" use="@c"/>
<xsl:template match="e1" mode="trans">
<xsl:copy>
<xsl:for-each select="b">
<xsl:choose>
<xsl:when test="key('trans', .)/@b1">

.)/@b1"/></b>
</xsl:when>
<xsl:otherwise>
<b><xsl:value-of select="."/></b>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:copy>
</xsl:template>
<xsl:template match="e2" mode="trans"/>
<xsl:template match="e3" mode="trans"/>
<xsl:template match="/">

<xsl:apply-templates/>
</xsl:template>
</xsl:stylesheet>
Many thanks in advance,
