Subject: Re: [xsl] fastest way to do projection in xsl
Hello Kasper,
a nice and short stylesheet already solves your problem. It contains
only of the identity transformation template (copies everyting to the
output, that is matched), a template for all (to not copy the view) and
a template matching on the project elements, that contains the important
logic.
<xsl:template match="all">
<xsl:apply-templates select="projects"/>
</xsl:template>
<xsl:template match="project">
<xsl:copy>
<xsl:variable name="thisProject" select="."/>
<xsl:for-each select="/all/view/columns/measure">
<xsl:apply-templates select="$thisProject/measure[(_at_)name =
current()/@name]"/>
</xsl:for-each>
</xsl:copy>
</xsl:template>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
I think it's easy to understand, isn't it?
Regards,
Joerg

Hello,
Basicly what im looking for is how to (fastest possible way) do a
project
(relational algebra) operation on a long list of relations in xsl
Let's say I have this document
<all>
<view name="economy">
<columns>
<measure name="economy_estimate"/>
<measure name="economy_actual"/>
<measure name="responsible"/>
</columns>
</view>
<projects>
<project>
<measure name="responsible"> kav </measure>
<measure name="economy_actual">991233</measure>
<measure name="economy_estimate">881123</measure>
<measure name="schedule_actual">123</measure>
<measure name="schedule_estimate">823</measure>
</project>
<project>
<measure name="responsible"> pjc </measure>
<measure name="economy_actual">77123123</measure>
<measure name="economy_estimate">44123123</measure>
<measure name="schedule_actual">723</measure>
<measure name="schedule_estimate">923</measure>
</project>
..... 100's of other projects....
</projects>
</all>
how do I transform this document into something like this with xsl
The order between measures is as defined in the view part, ie (estimate
before actual) before responsible
<projects>
<project>
<measure name="economy_estimate">881123</measure>
<measure name="economy_actual">991233</measure>
<measure name="responsible"> kav </measure>
</project>
<project>
<measure name="economy_estimate">44123123</measure>
<measure name="economy_actual">77123123</measure>
<measure name="responsible"> pjc </measure>
</project>
</projects>
