Answer 1

There are a few problems here, for starters, here the JSON string variable either needs to have it's quotes escaped. Or be wrapped in single quotes. For example:

var InputJSON = '{"body":{"entry": [{ "fullURL" : "abcd","Resource": "1234"},{ "fullURL" : "efgh","Resource": "5678"}]}}';

Next, there is no need to use eval here, when using JSON in JavaScript you should use JSON.parse

// First parse the JSON
var InputJSON = JSON.parse(InputJSON);

// Now execute the 'OBJtoXML' function
var output = OBJtoXML(InputJSON);

Now we come to the meat of this question, why is entry only occuring once? The problem that you're having is that xml += "<" + prop + ">"; and xml += ""; are only happening once per property. A possible solution would look like this:

function OBJtoXML(obj) {
    var xml = '';
    for (var prop in obj) {
        xml += "<" + prop + ">";
        if(Array.isArray(obj[prop])) {
            for (var array of obj[prop]) {

                // A real botch fix here
                xml += "";
                xml += "<" + prop + ">";

                xml += OBJtoXML(new Object(array));
            }
        } else if (typeof obj[prop] == "object") {
            xml += OBJtoXML(new Object(obj[prop]));
        } else {
            xml += obj[prop];
        }
        xml += "";
    }
    var xml = xml.replace(/<\/?[0-9]{1,}>/g,'');
    return xml
}
