XML Attribute Selector (.@myKey)

.@myKey selects an attribute in an XML element.

Using .@ without the key name returns an object containing the attributes as key-value pairs.

This DataWeave example reads an XML sample into a variable and uses @ to select attributes from the XML.

DataWeave Script:

%dw 2.0

var myVar = read(‘<product id=”1″ type=”electronic”>

  <brand>SomeBrand</brand>

</product>’, ‘application/xml’)

output application/json

—

{

  item: [

      {

      “type” : myVar.product.@.”type”,

      “name” : myVar.product.brand,

      “attributes”: myVar.product.@

    }

  ]

}

Output JSON:

{

  “item”: [

    {

      “type”: “electronic”,

      “name”: “SomeBrand”,

      “attributes”: {

        “id”: “1”,

        “type”: “electronic”

      }

    }

  ]

}
