var obj = {
name: {
text: {
_attr: {
"xml:lang": "de-DE"
},
_value: "The german description for HelloWorldDisplayManaged application"
},
_value: "The HelloWorldDisplayManaged application"
}
}

I used the above object to generate;

The HelloWorldDisplayManaged applicationThe german description for HelloWorldDisplayManaged application
