json_path_multi

Extracts all matching values from a dictionary or list using a JSON path expression. Unlike json_path, which returns only the first match, this function returns a list of all matches.

Syntax

json_path_multi(path, obj)

Parameters

Name	Type	Required	Description
path	string	Yes	A JSON path expression specifying the locations to extract.
obj	dict or list	Yes	The dictionary or list to search.

Returns

Type: list

A list of all values found at the specified path.

Examples

Extract all names from a list of objects:

json_path_multi("[*].name", [users])

If users is [{"name": "Alice"}, {"name": "Bob"}, {"name": "Charlie"}], the result is ["Alice", "Bob", "Charlie"].

Filter with a condition:

json_path_multi("$[?age < 30].name", [users])

If users is [{"name": "Alice", "age": 35}, {"name": "Bob", "age": 25}, {"name": "Charlie", "age": 20}], the result is ["Bob", "Charlie"].

Combine with join to produce a string:

join(", ", json_path_multi("[*].email", [contacts]))

If contacts is [{"email": "[e-mail]"}, {"email": "[e-mail]"}], the result is "[e-mail], [e-mail]".

Notes

• Uses the jsonpath-ng library for path resolution, supporting advanced expressions such as wildcards, filters, and recursive descent.
• Returns an empty list if no matches are found.
• Use json_path instead if you only need the first matching value or want a fallback for missing data.
