是否有与XQuery/XPath等价的JSON ?

当在复杂的JSON数组和散列中搜索项时，比如:

[
    { "id": 1, "name": "One", "objects": [
        { "id": 1, "name": "Response 1", "objects": [
            // etc.
        }]
    }
]

是否有某种查询语言，我可以用来在[0]中找到一个项目。id = 3的对象?

我知道的其他选择是

JSONiq specification, which specifies two subtypes of languages: one that hides XML details and provides JS-like syntax, and one that enriches XQuery syntax with JSON constructors and such. Zorba implements JSONiq. Corona, which builds on top of MarkLogic provides a REST interface for storing, managing, and searching XML, JSON, Text and Binary content. MarkLogic 6 and later provide a similar REST interface as Corona out of the box. MarkLogic 8 and later support JSON natively in both their XQuery and Server-side JavaScript environment. You can apply XPath on it.

HTH.

试试这个——https://github.com/satyapaul/jpath/blob/master/JSONDataReader.java

这是一个非常简单的实现，类似于xpath for xml。它的名称是jpath。

是的，它叫做JSONPath:

它还集成到DOJO中。

为了增加更多的选择，还有XPath。XPath 3.1处理JSON和XML。在XPath 3.1中，您需要的查询是?0?Objects?*[?id = 3)

ObjectPath是一种类似于XPath或JSONPath的查询语言，但由于嵌入了算术计算、比较机制和内置函数，它的功能要强大得多。请看语法:
