Alan Foster commented on CAMEL-5550:
------------------------------------
I will try to see what I can do with this one... I'm new to camel development
so I may be slow, so if someone else is eager to add this functionality just
say and I'll stop :)
> Add headerName option to xpath/xpath language
> ---------------------------------------------
>
> Key: CAMEL-5550
> URL: https://issues.apache.org/jira/browse/CAMEL-5550
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Reporter: Claus Ibsen
> Priority: Minor
> Fix For: 2.11.0
>
>
> We recently added headerName to @XPath / @XQuery to support doing xpaths on
> headers. We should add that as well to the xpath/xquery languages so its
> exposed in the DSL, so people can use that.
> For example in a content based router. Today there is some functions that
> return a header, but its a bit cumbersome to use. Maybe people have stored a
> xml in a header, and just want the xpath to evaluate on that.
> The Java / Scala DSL is a bit heavier to add, as it would entail new methods
> in various builder classes to support that. And we got a bunch already for
> the namespaces, and return type etc. So be selective and only add a few for
> the header which makes the most sense. People can always create the
> expression/predicate using the xpath builder itself.
