Re: simpel cocoon question

Hello Hussayn,

the question was also on the XSL list yesterday and there is a simpler solution:

http://www.biglist.com/lists/xsl-list/archives/200211/msg00188.html

Furthermore version="1.1" is only supported in pre-implementations of Saxon. XSL 1.1 died in Working Draft status.

Regards,

Joerg

Hy;

The stylesheet below will do it. The trick is recursively
calling the template "project-measure".
I would be interested, if there is a more elegant/efficient
way, doing this in xslt or inside of cocoon ...

regards, hussayn


<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version='1.1'>

<xsl:output indent="yes"/>

<xsl:variable name="measure-count" select="count(/all/view/columns/measure)"/>

<xsl:template match="projects">
<projects>
<xsl:apply-templates/>
</projects>
</xsl:template>

<xsl:template match="project">
<project>
<xsl:call-template name="project-measure"/>
</project>
</xsl:template>

<xsl:template name="project-measure">
<xsl:param name="position">1</xsl:param>
<xsl:variable name="name" select="../../view/columns/measure[position()=$position]/@name"/>
<xsl:apply-templates select="measure[@name=$name]"/>
<xsl:if test="$position &lt; $measure-count">
<xsl:call-template name="project-measure">
<xsl:with-param name="position" select="$position + 1"/>
</xsl:call-template>
</xsl:if>
</xsl:template>

<xsl:template match="project/measure">
<xsl:copy-of select="."/>
</xsl:template>

</xsl:stylesheet>

Thanks for the hints, aggregation is the way to go for sure, but im still
facing a problem

Basicly what im looking for is how to (fastest possible way) do to a project
(relational algebra) operation on a long list of relations in xsl.
Im not sure this should be done in xsl perhaps I need a custom transformer
anyway

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:
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>

Kasper

Subject: simpel cocoon question



Just started using Cocoon and I have a rather simple question:

Lets say i have a document with all my data (projects.xml)
<projects>
   <project id="A1">
       <name> RailwayTrack DF</name>
       <responsible> kni </responsible>
       <economy_actual>123</economy_actual>
       <economy_estimate>456</economy_estimate>
       <schedule_estimate>789</economy_estimate>
   </project>
   <project id="B4">
       <name> Digital Transmission </name>
       <responsible> pjc </responsible>
       <economy_actual>987</economy_actual>
       <economy_estimate>654</economy_estimate>
       <schedule_estimate>321</economy_estimate>
   </project>
   ............
</projects>

And i also have a definition of some views of the data (views.xml)

<views>
   <view name="estimate">
       <columns>
           <measure name="schedule_estimate"/>
           <measure name="economy_estimate"/>
       </columns>
   </view>
   <view name="overview">
       <columns>
           <measure name="name"/>
           <measure name="responsible"/>
       </columns>
   </view>
</views>

Now I want to given the name of the view, lets say "estimate" to combine


it
into another xml document, that is extract only the data mentioned in the
view, in this case it would be the "schedule_estimate" column and the
"economy_estimate" column
The resulting document should look something like this
<table>
<columndefs>
<columndef>
<column-name>schedule_estimate</column-name>
</columndef>
<columndef>
<column-name>economy_estimate</column-name>
</columndef>
</columndefs>
<tabledata>
<row>
<entry>456</entry>
<entry>789</entry>
</row>
<row>
<entry>654</entry>
<entry>321</entry>
</row>
</tabledata>
</table>

Can I "merge" 2 documents in that way with xslt?
Or do I need a custom transformer?

Kasper Nielsen
