Talend Data Mapper - JSON -> XML - Add line break

Hi everyone,
I want to add a line break after each tag like this:
<Product>1 </ product>
<Product>2 </ product>
<Product>3 </ product>
<Product>4 </ product>
</ Products>
But today even if I inform the terminator I have this:
<products><product>1</ product>2<product>3</ product></products>
Do you have an idea to do this in the XML structure
Thank you for your help !
