Powershell:如何在Json和XML对象中更新/替换数据和值 [英] Powershell: How to Update/Replace data and values in Json and XML Object

问题描述

所以我在这里有一个问题，我似乎无法弄清楚如何更新对象中的数据值

So I am having a bit of a problem here, I can't seem to figure out how to update data values in an Object

因此，例如说FOLLOWING json

so lets say for example the FOLLOWING json

{
    "People": 263,
    "Hungry": true,
    "Fruits": {
        "Apples": 1 "Oranges": 2
    },
    "Places": {
        "Places": [{
                "Baskets": "true",
                "name": "Room 1",
                "candycount": 1500,
                "candytypespresent": {
                    "candies": [
                        "caramel"
                    ]
                }

            },
            {

                "Baskets": "false",
                "name": "Room 2",
                "candycount": 2000,
                "candytypespresent": {
                    "candies": [
                        "caramel",
                        "jawbreaker",
                        "butterscotch"
                    ]
                }
            }
        ]
    }
}

我让Powershell使用convertfrom-json

I have Powershell read it smoothly with convertfrom-json

我将如何执行以下操作:

A)将橙色"从"2"更改为"100"

A) Change "Oranges" from "2" to "100"

B)2号会议室中的购物篮"，从假"到真"

B) "Baskets" in Room 2 from "false" to "true"

C)在Room1的糖果"中添加泡泡糖"

C) add "bubblegum" to "candies" in Room1

如何在不重写整个json或对象的情况下更新此内容?

推荐答案

JSON成为带有嵌套对象的自定义对象，因此确实非常简单.首先，让我们通过在Apples值之后添加逗号来修复JSON，然后将其转换为对象...

The JSON becomes a custom object with nested objects, so really it is fairly simple. To start, let's fix the JSON by adding a comma after the Apples value, and convert it to an object...

$JSON = @'
{
"People":  263,
"Hungry":  true,
"Fruits":  {
                "Apples":  1,
                "Oranges":  2
            },
"Places":  {
              "Places":  [
                            {
                                "Baskets":  "true",
                                "name":  "Room 1",
                                "candycount":  1500,
                                "candytypespresent":  {
                                                     "candies":  [
                                                                     "caramel"
                                                                 ]
                                                 }

                            },
                            {

                                "Baskets":  "false",
                                "name":  "Room 2",
                                "candycount":  2000,
                                "candytypespresent":  {
                                                     "candies":  [
                                                                    "caramel",
                                                                    "jawbreaker",
                                                                    "butterscotch"                                                                    
                                                                ]
                                                }
                            }
                        ]
          }
}

然后，如果我们要将Oranges从2更新为100，我们只需更改值即可:

Then if we want to update Oranges from 2 to 100 we simply change the value:

$JSON.Fruits.Oragnes = 100

类似地，我们可以通过简单地列出场所，将其传递到Where语句以获取正确的房间并在ForEach循环中修改值来修改Room 2.

Similarly we can modify the Room 2 by simply listing the Places, passing it to a Where statement to get the right room, and modify the value in a ForEach loop.

$JSON.Places.Places | Where{$_.name -eq 'Room 2'} | ForEach{$_.Baskets = 'true'}

最后，由于candies在JSON中定义为数组，因此我们可以简单地将所需的糖果添加到数组中.

Lastly, since candies is defined as an array in the JSON we can simply add the desired candy to the array.

$JSON.Places.Places | Where{$_.name -eq 'Room 1'} | ForEach{$_.CandyTypesPresent.candies += 'bubblegum'}
