如何使用try.zorba.io从JSON运行JSONiq [英] How to run JSONiq from JSON with try.zorba.io

问题描述

我需要编写一个JSONiq表达式，该表达式仅列出价格至少为3的产品名称.这是我在 XQuery 部分中键入的JSON文件:

I need to write a JSONiq expression that lists only the name of the products that cost at least 3. This is my JSON file which i had typed in the XQuery section:

{ "supermarket_visit":{
        "date":"08032019",
        "bought":[
            "item",{
                "type":"confectionary",
                "item_name":"Kit_Kat",
                "number": 3,
                "individual_price": 3.5
                },
            "item",{
                "type":"drinks",
                "item_name":"Coca_Cola",
                "number": 2,
                "individual_price": 3
                },
            "item",{
                "type":"fruits",
                "item_name":"apples",
                "number": "some"
                }
            ], 
"next_visit":[
            "item",{
                "type":"stationary",
                "item_name":"A4_paper",
                "number": 1
                },
            "item",{
                "type":"stationary",
                "item_name":"pen",
                "number": 2
                }
            ]
        }
}

这是我的JSONiq Xquery JSONiq命令，我真的不知道在哪里键入 try.zorba.io :

and this is my JSONiq Xquery JSONiq command, which i dont really know where to type in try.zorba.io:

let $x := find("supermarket_visit")
for $x in $supermarket.bought let $i := $x.item
where $i.individual_price <=3
return $i.item_name

我在try.zorba.io中遇到了很多错误，并且对JSONiq和JSON来说真的很新.我的JSON或JSONiq部分出问题了吗?

I am getting many errors in try.zorba.io and im really new to JSONiq and JSON. Is something wrong with my JSON or JSONiq part?

The following selection works for me at the site you linked to:

jsoniq version "1.0";
{ "supermarket_visit":{
        "date":"08032019",
        "bought":[
            "item",{
                "type":"confectionary",
                "item_name":"Kit_Kat",
                "number": 3,
                "individual_price": 3.5
                },
            "item",{
                "type":"drinks",
                "item_name":"Coca_Cola",
                "number": 2,
                "individual_price": 3
                },
            "item",{
                "type":"fruits",
                "item_name":"apples",
                "number": "some"
                }
            ],
"next_visit":[
            "item",{
                "type":"stationary",
                "item_name":"A4_paper",
                "number": 1
                },
            "item",{
                "type":"stationary",
                "item_name":"pen",
                "number": 2
                }
            ]
        }
}.supermarket_visit.bought()[$$ instance of object and $$.individual_price le 3].item_name
