Thanks Thomas. We started going down the CDATA route but ultimately just decided to use dom4j for the router section instead. The simplicity of dom4j/Xpath versus JiBX in this case was worth the slight performance hit. But we're still using JiBX outside the router in our services :)

The simple method is to adapt DiscardElementMapper.java to read the entire MsgPart tag into a string. The difficult part will be trying to write the string back, as JiBX will want to convert the angle brackets. For example, it will want to marshal to : <MsgParts type="test"> <test> <davetest>asdfasdf</davetest> </test> </MsgParts> There are three ways around this: Include it in a CDATA section, hack the JiBX code, or unmarshall it into DOM structure. The first you don't like, but it is the fastest. It may not be unmarshallable by the end code either. I've done the second in an earlier version of JiBX. Essentially you need to expose (make public) the IXMLWriter so you can write around the default methods of writing text. This was in an earlier version, and the changes required have changed. And I've lost them in the upgrades. The third you want to look at the Dom4JMapper.java and other related classes. It won't be pretty, but if you are not changing or looking at the data, it may work. -- Thomas Jones-Low Softstart Services Inc.
