Re: Filter mediator - SOAP1.2

Paul,

I don't think that is possible with the current model of the filter, because filter is just doing the filtering depending on the XPATH expression provided. So, it is the users responsibility to give the right XPATH. If synapse is going to be intelligent and do the soap version mapping for the user, he will miss the ability of filtering the soap11 messages over soap12 messages.

Also if we are going to support this then we need to hack in to the XPATH expression provided by the user and change it on the mediator build time to incorporate both soap namespaces. I don't see this as a good solution.

If we can introduce some other mechanism than the XPATH one, then we will be able to support both soap versions, but in that case the expression that the user is providing is not gonna be a standard XPATH. (may be some kind of a regular expression)

WDYT?

Thanks,
Ruwan.

Neat trick Ruwan. However, I think we should also look at doing some
help inside Synapse to abstract which version of SOAP the message is
in.
