How to duplicate part of tags in XML in Jmeter

Question

I have this JSON template

{ 
    "shipToAddress":{ 
        "country":"SE", 
        "emailAddress":"[email protected]", 
        "zipCode":"${zipcode}"
        }, 
    "itemLines":{ 
        "itemLine":[ 
            { 
                "bundleParentId":"", 
                "id":"IL1", 
                "itemType":"ART", 
                "itemNo":"${Article}", 
                "requiredQty":10, 
                "unitOfMeasure":"Piece" 
            }
        ] 
    }, 
    "checkCapacity":"true",

        "itemLine":[ 
            { 
                "bundleParentId":"", 
                "id":"IL1", 
                "itemType":"ART", 
                "itemNo":"${Article}", 
                "requiredQty":10, 
                "unitOfMeasure":"Piece" 
            }
        ] 
    }, 
    "checkCapacity":"true", 
    "checkInventory":"true", 
    "businessUnit":{ "type":"STO", "code":"856" } 
}

To start with, your expected addition to the template is incorrect and would error out as invalid JSON. Unless the system allows multiple itemLines objects, you really want to be adding a second itemLine to the to the itemLines array.

Some basic JSON terminology:

• An element is in the form "something" - think of this as the string equivalent in other language
• An object is in the form {"thing1":"value","thing2":value"} - this is made up of key:value pairs, similar to a map or dict in other languages
• An array is in the form [{"a":1, "b":2}, "element"] - is an array that can hold various items, seperate by commas

In your template you have:

• a shipToAddress object;
• an itemLines object which contains an
  • itemLine array of objects implied to be item lines;
• a checkCapacity element;
• a checkInventory element; and
• a businessUnit object.

To add extra itemLines your JSON should look more like this:

{ 
    "shipToAddress":{ 
        "country":"SE", 
        "emailAddress":"[email protected]", 
        "zipCode":"${zipcode}"
    }, 
    "itemLines":{ 
        "itemLine":[ 
            { 
                "bundleParentId":"", 
                "id":"IL1", 
                "itemType":"ART", 
                "itemNo":"${Article}", 
                "requiredQty":10, 
                "unitOfMeasure":"Piece" 
            },
            { 
                "bundleParentId":"", 
                "id":"IL1", 
                "itemType":"ART", 
                "itemNo":"${Article}", 
                "requiredQty":10, 
                "unitOfMeasure":"Piece" 
            }
        ] 
    }, 
    "checkCapacity":"true", 
    "checkInventory":"true", 
    "businessUnit":{ "type":"STO", "code":"856" } 
}

You should also consider passing in ID as a variable, or you could be violating a constraint elsewhere.
