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”
}
}
]
}
