具有嵌套数组的对象数组的Jsonpath

Question

I am trying to write a jsonpath for following object:

{
    "ParentArray": [
        {
            "ChildArray": [
                {
                    "ChildArrayObjectKey": "ChildArrayObjectValue1"
                },
                {
                    "ChildArrayObjectKey": "ChildArrayObjectValue2"
                }
            ]    
        },
        {
             "ChildArray": [
                {
                    "ChildArrayObjectKey": "ChildArrayObjectValue3"
                },
                {
                    "ChildArrayObjectKey": "ChildArrayObjectValue4"
                }
            ]  
        }  
    ]
}

Which would extract the object from the ParentArray. I am looking for an object which contains a value 'ChildArrayObjectValue3' in its ChildArray. The solution I think should work is:

$.ParentArray[?(@.ChildArray[?(@.ChildArrayObjectKey === 'ChildArrayObjectValue3')])]

But unfortunately it does not provide any results. What I would like to extract is:

{
    "ChildArray": [
        {
            "ChildArrayObjectKey": "ChildArrayObjectValue3"
        },
        {
            "ChildArrayObjectKey": "ChildArrayObjectValue4"
        }
    ]  
}

Answer 1

试试这种方式：$ .ParentArray .. * [？（@。ChildArrayObjectKey =='ChildArrayObjectValue3'）]
