问题
Is it possible to find a property name that matches a regex pattern (or at least starts with) using JSON Path. In XPath I can use name() but I haven't been able to find the JSON Path equivalent.
Basically, I what to find all property names that start with x-. Something like $..x-*.
I'll be interested in using any javascript package that does this. Currently, I'm using JSONPath.
回答1:
From my googling this is not possible in standard json path. However, the JSONPath package extends the specification with @path; and makes the following possible
$..[?(@path.includes("[\'x-"))]
The above assumes you are using ES6.

You can use regular expression using =~ left matches regular expression. For more in formation visit https://github.com/jayway/JsonPath
[?(@.name =~ /foo.*?/i)]
