Mule Dataweave Repeating XML Elements to Individually Named XML Elements -

input xml

<address>     <street>street line 1</street>     <street>street line 2</street>     <street>street line 3</street>     <city>city</city>     <postcode>0000</postcode> </address> 

output xml required

<deliveryaddress>     <da1>street line 1</da1>     <da2>street line 2</da2>     <da3>street line 3</da3>     <city>city</city>     <postcode>0000</postcode> </deliveryaddress> 

how can use dataweave put each street element particular da element in outbound xml?

i've tried use *wildcard (address.*street) puts street elements child element:

<deliveryaddress>     <da1>         <street>street 1</street>         <street>street 2</street>         <street>street 3</street>     </da1>     <city>city</city>     <postcode>0000</postcode> </deliveryaddress> 

please ^_^

the * wildcard used reference repeated elements, in xml format. start point can sequentially solve problem:

1. start expression payload.address.*street list of street.
2. however, error occur if directly use in current dataweave expression. therefore wrap expression inside bracket: (payload.address.*street) make object instead of array.
3. now need rename street tag correspond da(n). hence can utilize map operator iterate each record, , use brackets or quote marks, () or '' or "" enclose keys of output:

("da" ++ $$ + 1) or "da$($$ + 1)" both equally returning same result: da1, da2, da3, ...

therefore, complete expression field should be: (payload.address.*street map { ("da" ++ $$ + 1): $ })
