How to write Attributes from XML to Json - DW2

In project development sometimes we needed to convert the payload from xml to json. We also need to write the xml attributes after transformation. 

For this purpose we can use writeAttributes=true in header section of data-weave. This attribute is available from Dataweave2.

Please find the snippets below:

Sample XML Input:

<users>
<user>
<personal_information>
<first_name version="V1">Manish</first_name>
<middle_name>Kumar</middle_name>
<last_name>Sah</last_name>
</personal_information>
</user>
</users>

Dataweave Script

%dw 2.0
output application/json writeAttributes=true
---
payload

Output:
{
  "users": {
    "user": {
      "personal_information": {
        "first_name": {
          "@version": "V1",
          "__text": "Manish"
        },
        "middle_name": "Kumar",
        "last_name": "Sah"
      }
    }
  }
}

Happy Learning :)
