Recursive traversal missing

[kvetoslavnovak]

First of all thank you very much for this great library which helped us with our project a lot!!!

Only feature that we really miss is that JMESPath doesn't have recursive traversal. Like the standard feature // in XPath or .. in JsonPath.

Thank you very much for your response

Can you give a use case? or example of what you're trying to achieve?

@kvetoslavnovak I believe the let() function coming to JMESPath Community sort of does what you want.

E.g. I am trying to get all TYPE_OF_DATE tags/nodes which are all over the different places in my XMLs. Using JSONPath library for the time being.
Example of my code:

  // using JSONPath to get all TYPE_OF_DATE  because JMESPath cannot do recursive traversal (to get non-rooted expressions)
   let TYPE_OF_DATE = JSONPath({
     path: "$..TYPE_OF_DATE",
     json: JSONfile,
   });

Description of // XPath selector is for example here W3School - XPath Syntax

Thank you very much for this tip.

@springcomp thank you for the let()tip. But it does not seem to be exactly the right tool nor as easy to use as the others // or .. recursive traversal child selectors usually are.

@kvetoslavnovak I‘ve setup #148 to track this feature.

@springcomp thank you very much

@kvetoslavnovak We want to propose this feature to JMESPath and will include this in the next iteration for JMESPath Community.
