Frequently Asked Questions
What is JSONPath?
JSONPath is a query language for JSON data, similar to XPath for XML. It uses path expressions to navigate and extract data from JSON documents. The root element is represented by $ and you can access nested properties using dot notation or bracket notation.
What does the .. operator do?
The recursive descent operator (..) searches for the specified element at any depth in the JSON structure. For example, $..author finds all author properties anywhere in the document, regardless of how deeply nested they are.
How do filter expressions work?
Filter expressions use the syntax [?(@.property condition)] to select array elements that match a condition. For example, $..book[?(@.price<10)] selects all books with a price less than 10. The @ symbol refers to the current element being evaluated.
What is array slicing?
Array slicing uses the syntax [start:end:step] to select a range of elements. For example, [0:2] selects the first two elements, [:2] also selects the first two, and [-1] selects the last element. The step parameter is optional.
