[rules-users] how to use xml file instead of java object ?

[Jaroslaw Kijanowski]

Hi,
  have a look at the dsl:

http://anonsvn.jboss.org/repos/labs/labs/jbossesb/tags/JBESB_4_6/product/services/jbrules/src/main/resources/XPathLanguage.dsl

This rule expects an object of type org.jboss.soa.esb.message.Message 
which contains the XML in its body.

Also note that a lot of stuff is going on behind the scenes:
http://anonsvn.jboss.org/repos/labs/labs/jbossesb/tags/JBESB_4_6/product/services/jbrules/src/main/java/org/jboss/internal/soa/esb/services/routing/cbr/DslHelper.java

Drools Pipeline might be helpful in inserting XML data into sessions.

Cheers,
