Dear Peter and Kai,
I have tried this approach but I recieve the following Cocoon error:
XPDY0002 : variable '$p2' is not set. [at line 49, column 34]
org.apache.cocoon.ProcessingException: Failed to execute pipeline.:
org.apache.cocoon.ProcessingException: XMLDBException occurred: XPDY0002 :
variable '$p2' is not set. [at line 49, column 34]:
org.xmldb.api.base.XMLDBException: XPDY0002 : variable '$p2' is not set. [at
line 49, column 34]
cause: org.exist.xquery.XPathException: XPDY0002 : variable '$p2' is not
set. [at line 49, column 34]
The sitemap fragment is:
<map:match pattern="run/*/*">
<map:generate src="running-context.xq" type="xquery">
<map:parameter name="p1" value="{%1}"/>
<map:parameter name="p2" value="{%2}"/>
</map:generate>
<map:serialize encoding="UTF-8" type="xml"/>
</map:match>
and running-context.xq:
xquery version "1.0";
declare option exist:serialize "method=xml media-type=text/xml";
<running-context>
<parameter cocoon_name="p2">{$p2}</parameter>
</running-context>
Am I missing something?
Regards,
Thomas
