The xpath_json parser previously failed to correctly parse JSON array elements using XPath expressions like //array[1]/field. This was because the underlying jsonquery library treats arrays as single container nodes with unnamed children, making it impossible to index into arrays directly. This change modifies the JSON document handler to: - Convert JSON to CBOR format internally - Use cborquery for parsing, which correctly handles array elements as named siblings that can be indexed with XPath expressions The fix enables users to access JSON array elements using intuitive XPath syntax like //nvme_namespaces[1]/capacity/bytes instead of requiring the workaround //*[local-name()='nvme_namespaces']/*[1]/capacity/bytes. Note: This is a breaking change for some XPath query patterns: - Array selection: Use //array instead of //array/* to select elements - String representation of objects/arrays differs from JSON format Fixes influxdata#18145 Signed-off-by: majiayu000 <1835304752@qq.com>
