Subject [jira] [Commented] (CAMEL-6238) support JSONPath as a Camel Language for easy JSON filtering and expression evaluation
Date Mon, 25 Nov 2013 12:19:36 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-6238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13831403#comment-13831403
] 

Guillaume commented on CAMEL-6238:
----------------------------------

Very quick addition! Does it make sense to add the parameter resultType to the JsonPathExpression
constructor?
The returned value is a list of values within square brackets, even if there is only one match
- it is not very pretty in if a simple string is expected. I think it would be good to have
the facility of get a single result, for instance a parameter returnFirstMatch.

> JSON is a very popular message format; yet its kinda painful performing expressions on
it as typically you have to marshal it first into some specific domain model (or Maps / Lists)
and then use some general purpose Java expression language on it.
> JSONPath looks pretty cool though; kinda like XPath but designed for arbitrary JSON payloads
> https://code.google.com/p/json-path/
> the library is small & Apache licensed so it should be pretty easy to wrap up as
a Camel Language
