Sometime the camel-scala DSL need changes as well. > Claus suggested improving the Namespace support to make it easier for users > to declare namespaces.

This is a common mistake. <order xmlns="http://myorder.com";> ... </order> Then the xpath expression must use the htt://myorder.com namespace. But what would have been cool, would be for Camel to be able to detect if you do not have any namespace in the xpath expression. And that the XML Structure have 1 namespace assigned in the root tag, then we could auto default and use that namespace. I have tried to look into this in the past if that was possible. But the XPath API did not offer any way back then. Another problem is we should possible add some more logging/tracing of the evaluation process. As when people get the xpath wrong, they do not know what is happening and why its wrong. And it can take some time to figure this out. So if there was some way of enabling logging or just that we have more DEBUG logging in the xpath builder then that is a good start. > Anything else springs to mind? > > Regards, > Raúl. -- Claus Ibsen ----------------- FuseSource Email: cib...@fusesource.com Web: http://fusesource.com Twitter: davsclaus, fusenews Blog: http://davsclaus.blogspot.com/ Author of Camel in Action: http://www.manning.com/ibsen/
