问题 There are many query languages for JSON, such as JMES Path and JSON Path, but none of the ones I've found interest me, e.g. JSON Path doesn't allow multiselect query (I can't return a list with different type element [car, plane, boat]) and JMES Path is really simpler compare to the JSON Path and allow the multiselect but doesn't allow the access to the parent node like .. or parent(@) or $(for the source). So I want a language which can do both, if it's possible a query language simple as

JMESpath expression to filter object by property and return list of object names having this property set

由 喜夏-厌秋 提交于 2019-12-11 00:43:37
问题 Is it possible to write JMESPath expression to return a list of object names where a specific subproperty value is set?

ansible json-query path to select item by content

问题 Does anyone know what json-query filter can be used to select Tigger's food in the sample JSON below? The JSON is a simplified stand-in for a massive and relatively complicated AWS blob. Some background: I was rather pleased to discover that Ansible has a json-query filter. Given that I was trying to select an element from an AWS JSON blob this looked as if it was just what I needed. However I quickly ran into trouble because the AWS objects have tags and I needed to select items by tag. I
