2nd Re: xml 2 svg in coplet

[hgadm]

Thanks Jens it works, good tip :-)

- however, two questions from a bloody newby :-o

1.) The chart updates only (i.e. only reads-in a
modified xml data source) if I clear the portal cache
or close and restart Cocoon. Simple page refresh and
logoff/-on doesn't help !!?? What did I forget ?

2.) I am not sure what generator to use in the coplet.
It still works with the xml data file here but I guess
this is not necessary because the handling is already
done in the respective pipeline. So what to put in here
?

Kind regards,
Holger

Below is what I have done (using 2.1 dev):

...
<map:pipeline>

    <map:match pattern="histochart.jpeg">
        <map:generate
src="http://localhost:8080/~Owner/My%20Website/cocoon/svg/sales.xml"/>
        <map:transform
src="http://localhost:8080/~Owner/My%20Website/cocoon/svg/sales.xsl"/>
        <map:serialize type="svg2jpeg"/>
    </map:match>

     <!-- This is the Cocoon Demo Portal Pipeline -->
        <map:match pattern="sunspotdemoportal">
...


...
                <!-- sunlets -->

                <map:match pattern="sunspotdemosunlet-svgchart.xml">
                  <map:generate
src="http://localhost:8080/~Owner/My%20Website/cocoon/svg/sales.xml"/>
                  <map:transform src="styles/sunLet_chart.xsl"/>
                  <map:serialize type="xml"/>
                </map:match>
...

the sunlet_chart.xsl is pretty lean:

<?xml version="1.0"?>

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

<xsl:template match="*">

<table border="0" bgcolor="ffffff" width="" height=""
cellpadding="1" cellspacing="1"> 
<img
src="http://localhost/cocoon/samples/portal-fw/histochart.jpeg"; />
</table>
  
</xsl:template>
</xsl:stylesheet>
