Hi, Say for example used a proxy below [1] to convert an xml to json.
[1] <proxy xmlns="http://ws.apache.org/ns/synapse"; name="XmlToJSON" transports="https,http" statistics="disable" trace="disable" startOnLoad="true"> <target> <inSequence> <property name="messageType" value="application/json" scope="axis2"/> <respond/> </inSequence> </target> <description/> </proxy> using a payload like [2] returns a response like [3] with a json array. [2] <users> <user>user1</user> <user>user2</user> </users> [3] { "users": { "user": [ "user1", "user2" ] } } using a payload like [4] returns a response like [5] without square brackets, since there's only one element. [4] <users> <user>user1</user> </users> [5] { "users": { "user": "user1" } } But I need to get this user1 in an array even if there's only one element in the array. I can however use a payload factory with a filter mediator like below to achieve this. Wondering if there's any other simple way to achieve without this? Your input is appreciated. [6] <filter source="json-eval($.StockQuotes.Stock.Symbol)" regex="null"> <then> <payloadFactory media-type="json"> <format>{ "StockQuotes": { "Stock": $1 } }</format> <args> <arg evaluator="json" expression="$.StockQuotes.Stock"/> </args> </payloadFactory> </then> <else> <payloadFactory media-type="json"> <format>{ "StockQuotes": { "Stock": [ $1 ] } }</format> <args> <arg evaluator="json" expression="$.StockQuotes.Stock"/> </args> </payloadFactory> </else> </filter> Shazni Nazeer Mob : +94 777737331 LinkedIn : http://lk.linkedin.com/in/shazninazeer Blog : http://shazninazeer.blogspot.com
