Hi Carsten,
I'm using a version from a couple of months ago. I'll
get the latest and try it again and let you know.
While I have your attention, I've asked another
question a couple of days ago about getting parameter
values from the request. Could you take a look at it,
I'm pasting it below:
Hi,
I'm looking for help in how to extract parameter
values using SessionTransformer.
My uri looks like this:
myaction?item=1&item=2&item=3
The SessionTransformer generates the following path:
<parametervalues>
cinclude:parameters>
<cinclude:parameter>
<cinclude:name>item</cinclude:name>
<cinclude:value>1</cinclude:value>
</cinclude:parameter>
</cinclude:parameters>
</parametervalues>
My goal is to turn this into the following xml:
<items>
<item>1</item>
<item>2</item>
<item>3</item>
</items>
Two questions:
1. SessionTransformer javadoc says: This output has
the namespace of the CIncludeTransformer to use it as
input for a <cinclude:includexml> command. I don't
quite understand how I would make use of CIclude
transformer.
2. I've tried doing the following:
<items
xmlns:session="http://cocoon.apache.org/session/1.0";
xmlns:cinclude="http://apache.org/cocoon/include/1.0";>
<session:getxml
xmlns:cinclude="http://apache.org/cocoon/include/1.0";
context="request"
path="/parametervalues/cinclude:parameters/cinclude:parameter[cinclude:name='item']/cinclude:value"/>
</items>
So that I could later transform it to the xml I need,
but I get the following error:
"Prefix must resolve to a namespace: cinclude"
Thanks,
-Alex
P.S. And the stack:
org.apache.cocoon.ProcessingException:
TransformerException:
javax.xml.transform.TransformerException: Prefix must
resolve to a namespace: cinclude:
javax.xml.transform.TransformerException: Prefix must
resolve to a namespace: cinclude
