How do filter expressions work?

Filters use the ?() syntax with @ referring to the current node: $.books[?(@.price , =, and string matching. Multiple conditions: [?(@.price < 20 && @.category == "fiction")].

Q: What is JSONPath?

JSONPath is a query language for JSON similar to XPath for XML. The $ symbol represents the root object. You can navigate with dots ($.key), brackets ($['key']), wildcards ($[*]), recursive descent ($..), and filter expressions ($[?(@.price > 10)]).

Frequently Asked Questions

JSONPath is a query language for JSON similar to XPath for XML. The $ symbol represents the root object. You can navigate with dots ($.key), brackets ($['key']), wildcards ($[*]), recursive descent ($..), and filter expressions ($[?(@.price > 10)]).

$.. is the recursive descent operator — it searches all levels of the JSON structure. $..name finds all "name" properties at any depth. $.store..price finds all "price" values within the store object at any nesting level.

Filters use the ?() syntax with @ referring to the current node: $.books[?(@.price < 20)] finds books where price is under 20. You can use ==, !=, <, >, <=, >=, and string matching. Multiple conditions: [?(@.price < 20 && @.category == "fiction")].
