----------------------------------
Summary: 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.
