问题
I am trying to parse an XML recursively to create JSON array using dataweave 2 but I am not able to do so.
My Input XML is given below -

I want to create JSON array of all the BOMs (a flat structure with no hierarchy) as shown below -
Output -
[
{
"id": "5637300477",
"productId": "96AR169X",
"parentId": null
},
{
"id": "111111111",
"productId": "96AR060W",
"parentId" : "BOM011986"
},
{
"id": "222222",
"productId": "96AR158",
"parentId" : "BOM011986"
},
{

},
{

},
.

I not able to figure it out the use of recursion in this case. I am quite new to Dataweave language as it is functional language. I am used to Java language.
Thanks in advance for help !!!
回答1:
You can make use of descendant data selector (using ..) to retrieve all BOMTable from your xml document and thus there is no need to recursively navigate through your document. Then using map/flatMap to output the necessary fields.
Please see below dataweave:
%dw 2.0
output application/json
---
payload..*BOMTable flatMap (bomTable) -> bomTable.*BOM map (bomValue) ->
{
id: bomValue.RecId,
productId: bomValue.ItemId,
parentId: bomTable.RecId
}
Output will be as follows:
[
{
"id": "5637300477",
"productId": "96AR169X",
"parentId": "5637160605"
},
{
"id": "5637300487",
"productId": "9646095W",
"parentId": "5637160605"
},
{
"id": "5637300488",
"productId": "9648376X",
"parentId": "5637160605"
},
{
"id": "5637300489",
"productId": "9643908X",
"parentId": "5637160605"
},
{
"id": "5637300490",
"productId": "9642837X",
"parentId": "5637160605"
},
{
"id": "111111111",
"productId": "96AR060W",
"parentId": null
},
{
"id": "222222",
"productId": "96AR158",
"parentId": null
},
{
"id": "333333333",
"productId": "96AR582O",
"parentId": null
},
{
"id": "4444444",
"productId": "G211249",
"parentId": null
},
{
"id": "55555555",
"productId": "G25583954_46",
"parentId": null
},
{
"id": "66666666",
"productId": "G211249",
"parentId": "333333333"
},
{
"id": "77777777777",
"productId": "G25583954_46",
"parentId": "333333333"
},
{
"id": "888888888",
"productId": "9645340X",
"parentId": null
},
{
"id": "9999999999",
"productId": "9644384Y",
"parentId": null
},
{
"id": "101010101",
"productId": "9642737Y",
"parentId": "555555555"
},
{
"id": "1112112112",
"productId": "9642736Y",
"parentId": "555555555"
},
{
"id": "13131313",
"productId": "9644384Y",
"parentId": null
}
]
Note that the output is still different from the expected output that you posted which I think is incorrect based on the mapping rules you posted in one of your comments.
