Re: Value dependency between nested attributes

Output format shall be same than input format (XML-->XML Transformation):

<A name="a" test1="vw" test2="cd" test3="ef" test4="gh"/>
<A name="b" test1="vw" test2="cd" test3="ef" test4="gh" test7="ee"/>
<A name="c" test1="vw" test2="cd" test3="ef" test4="gh"/>
<A name="d" test1="xy" test2="ij" test3="kl" test4="mn" test5="op"/>

I want to give some params to the processor to change some (not all) "test" values. The values for the change depend on the value of the "name" attribute.

For example: if value of name = "a" then test2 value="$XX" and test3 value="$YY"
and if name="b" then test2 value="$VV" and test3 value="$WW"
...
I tried to customize the "Identity change template" (http://www.dpawson.co.uk/xsl/sect2/identity.html#d5687e43 ) for my needs

T:\ftemp>type karl.xml
<test>
<A name="a" test1="vw" test2="cd" test3="ef" test4="gh"/>
<A name="b" test1="vw" test2="cd" test3="ef" test4="gh" test7="ee"/>
<A name="c" test1="vw" test2="cd" test3="ef" test4="gh"/>
<A name="d" test1="xy" test2="ij" test3="kl" test4="mn" test5="op"/>
</test>

T:\ftemp>xslt karl.xml karl.xsl
<?xml version="1.0" encoding="utf-8"?><test>
<A name="a" test1="vw" test2="XXX" test3="YYY" test4="gh"/>
<A name="b" test1="vw" test2="VVV" test3="WWW" test4="gh" test7="ee"/>
<A name="c" test1="vw" test2="cd" test3="ef" test4="gh"/>
<A name="d" test1="xy" test2="ij" test3="kl" test4="mn" test5="op"/>
</test>
T:\ftemp>type karl.xsl
<?xml version="1.0" encoding="US-ASCII"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:param name="XX">XXX</xsl:param>
<xsl:param name="YY">YYY</xsl:param>
<xsl:param name="VV">VVV</xsl:param>
<xsl:param name="WW">WWW</xsl:param>

<!--method one: testing and reconstituting the element-->
<xsl:template match="A[@name='a']">
  <xsl:copy>
    <!--preserve all attributes-->
    <xsl:apply-templates select="@*"/>
    <!--overwrite the attributes needing changing-->
    <xsl:attribute name="test2"><xsl:value-of select="$XX"/></xsl:attribute>
    <xsl:attribute name="test3"><xsl:value-of select="$YY"/></xsl:attribute>
    <!--act on the children-->
    <xsl:apply-templates select="node()"/>
  </xsl:copy>
</xsl:template>

<!--method two: acting only on the attributes-->
<xsl:template match="A[@name='b']/@test2">
  <xsl:attribute name="test2"><xsl:value-of select="$VV"/></xsl:attribute>
</xsl:template>
<xsl:template match="A[@name='b']/@test3">
  <xsl:attribute name="test3"><xsl:value-of select="$WW"/></xsl:attribute>
</xsl:template>

<xsl:template match="@*|node()"><!--identity for all other nodes-->
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>
