Subject [jira] Commented: (CAMEL-1605) Passing an xml fragment as a parameter to an xslt transformation fails
Date Fri, 15 May 2009 11:52:51 GMT

    [ https://issues.apache.org/activemq/browse/CAMEL-1605?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=51714#action_51714

Gert-Jan van de Streek commented on CAMEL-1605:
-----------------------------------------------

I indeed found out that it is a more general problem. I have not been able to find a way to
solve the issue. In older version of xslt processors, this used to work. But nowadays, this
seems quite impossible. I have found numerous news posts with problems, but no answers.

> I pass an xml fragment to an xslt. I have the following code where the queue holds xml
messages
>        from("activemq:example.A")
>                .setHeader("agent.id", new XPathExpression("/"))
>                .process(new ReadLocalFile())
>                .to("xslt:transform.xsl")
> The xslt looks like:
>    ...
>    <xsl:param name="agent.xml"/>
> 	<xsl:template match="/">
> 		<xsl:value-of select="$agent.xml/agent/id" />
> I would expect the xml fragment to be available as a nodeset in the xsl, but I get the
following exception:
> javax.xml.transform.TransformerException: java.lang.RuntimeException: Invalid conversion
from 'com.sun.org.apache.xml.internal.dtm.ref.DTMNodeList' to 'node-set'.
