Delphi SuperObject - is there a (recursive) search function that tells where a value can be found?
I'm using SuperObject to create and manipulate a simple hierarchical structure in JSON.
My goal is to transform a set of objects {"id":..., "name":..., "parent":...} into a hierarchical structure. Example:
I want to transform this
{"id": "0001","name": "item0001", "parent":""},
{"id": "0002","name": "item0002", "parent":""},
{"id": "0003","name": "item0003", "parent":""},
{"id": "0003.1","name": "item0003.1", "parent":"0003"},
{"id": "0003.1.1","name": "item0003.1.1", "parent":"0003.1"},
into this
{
"items": [
{
"id": "0001",
"name": "item0001"
},
{
"id": "0002",
"name": "item0002"
},
{
"id": "0003",
"name": "item0003",
"items": [
{
"id": "0003.1",
"name": "item0003.1",
"items": [
{
"id": "0003.1.1",
"name": "item0003.1.1"
}
]
}
]
}
]
}
(This structure can vary, i.e. there is no fixed model. Which probably means the solution must be recursive).
I think the way to achieve this is:
- for each object to add,
- if there is no parent, add it to the output json, at the top;
- if there is a parent, find where the parent is in the output json.
- add the object to the output json under the parent.
To do this, I was looking for a way to retrieve the path of an object, like
function findpathinObject(key:string, value:string, object:iSuperObject):string
which would return the "path" of the value found.
In my example, findpathinObject("parent", "0003.1", newObject) would return 'items[2].items[0]'
Is this a good approach? Is there something that resolves my issue without making a new function?
the closest I've seen is this
SuperObject - Extract All
but I don't know if that can be changed to return the path it is looking in, or the path where it finally found the value...
Thanks

SuperObject is a JSON access library, not a data processing library. So there is nothing like this available in the box.
You just need to implement the extraction logic in pascal code, using SuperObject for reading the input, and creating the nested output.

Thanks. I noticed some built-in functions and I was wondering if anyone had seen some function (or implemented something) that would iterate through all the elements and keep track of the path. The problem description was also to get advice on whether I was looking at this the right way. I will try to implement it.
