我有一个 json 结构 (client_json)，如下所示：
client_json = { "data": [ { "attributes": { "creators": [ { "name": "This is a person", "nameType": "Personal", "givenName": "the", "familyName": "person" }, { "name": "This is an organization", "nameType": "Organizational", "givenName": "the", "familyName": "organization" } ] } } ] }
我正在尝试使用 jsonpath-ng 1.4.3 ( https://github.com/h2non/jsonpath-ng ) 来检索创建者名称。
from jsonpath_ng import jsonpath
from jsonpath_ng.ext import parse
这两个表达式给出了预期的结果：
[match.value['name'] for match in parse("data[*].attributes.creators[?(@.nameType='Personal')]").find(client_json)]
[match.value['name'] for match in parse("data[*].attributes.creators[?(@.nameType='Organizational')]").find(client_json)]
我试图将它们与 or 运算符结合起来，所有这些表达式都会产生解析错误：
parse("data[*].attributes.creators[?(@.nameType == 'Organizational' | @.nameType == …
