Hi Abel
thank you for your answer. Sorry when my instructions were confusing.
I give it another try, in fact the items template is a little bit more
complicated because I want to apply a grouping mechanism.
given the following xml:
<test>
<items>
<item>
<index>1</index>
<group>b</group>
<property>x</property>
<amount>1</amount>
</item>
<item>
<index>2</index>
<group>a</group>
<property>y</property>
<amount>3</amount>
</item>
<item>
<index>3</index>
<group>a</group>
<property>x</property>
<amount>6</amount>
</item>
</items>
</test>
I want to process this stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="test">
<myTest>
<xsl:variable name="xItems">
<xsl:copy-of select="items"/>
</xsl:variable>
<xsl:apply-templates select="items[item/property='y']"/>
</myTest>
</xsl:template>
<xsl:key name="groupKey" match="item" use="group"/>
<xsl:template match="items">
<xsl:for-each select="item[count(.| key('groupKey', group)[1]) = 1]">
<xsl:sort select="group"/>
<myGroup>
<xsl:attribute name="Name">
<xsl:value-of select="group"/>
</xsl:attribute>
<xsl:attribute name="Sum">
<xsl:value-of select="sum(key('groupKey',group)/amount)"/>
</xsl:attribute>
</myGroup>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
So the target is to have a group list with the corresponding sum of
amount, so I don't have a "item" template, but only an "items". But
therefore only the property=x items should be processed. Is that more
clear?
kind regards
Stefan

Hi Stefan,
The easy way out here is to add the filter to the matching template
instruction, and add another matching template for those that don't match,
or, if all "item" elements need to be processed in the same way, but item
with property=x need to be processed with an extra instruction, something
like this should work:
<xsl:template match="items">
<xsl:apply-templates select="item" />
</xsl:template>
<!-- called ONLY when property X is true -->
<xsl:template match="item[property='x']">
<myItem>
<xsl:value-of select="index"/>
</myItem>
</xsl:template>
<!-- called for all other situations (may leave empty if you don't want to
process them) -->
<xsl:template match="item">
<otherItem>
<xsl:value-of select="index"/>
</otherItem>
</xsl:template>
I have to note that I found your instruction a tad confusing, so if I
misunderstood, please try to clarify with a simplified input/output example
of XML.
Kind regards,
Abel Braaksma

and a stylesheet like:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="test">
<myTest>
<xsl:variable name="xItems">
<xsl:copy-of select="items"/>
</xsl:variable>
<xsl:apply-templates
select="items[item/property='y']"/><!-- wrong try! -->
</myTest>
</xsl:template>
<xsl:template match="items">
<xsl:for-each select="item">
<myItem>
<xsl:value-of select="index"/>
</myItem>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
I would like to pass only the items with property='x' to the items
matching template. The first try as written above of course doesn't
work, if there is an x item then the whole tree is passed, if there is
none, nothing is passed. I do further processing in the items
template, so I don't want to change it to match="item" or to apply the
filter in the items template.
Any help is much appreciated!
thanks, kind regards
Stefan
