How to get Magento Rest API result in XML format Using Scribe

I am using Scribe to use Magento Rest API, everything works fine but, i wanted to get result in XML format instead of Json, because Json result like below is very hard for me to parse using Talend Open Studio.

{"1": {
"entity_id":"1"
,"website_id":"1"
,"email":"my@gmail.com"
,"group_id":"1"
,"created_at":"2014-05-14 16:19:22"
,"disable_auto_group_change":"0"
,"firstname":"umesh"
,"lastname":"rakhe"
,"created_in":"dwetl" },"2":{
"entity_id":"2"
,"website_id":"2"
,"email":"my2@gmail.com"
,"group_id":"1"
,"created_at":"2014-05-14 16:19:22"
,"disable_auto_group_change":"0"
,"firstname":"ram"
,"lastname":"rakhe"
,"created_in":"dwetl" } }
