function OBJtoXML(obj, index) {

    for (var prop in obj) {

Xml-to-json library has method jsonToXml(json). I am the maintainer of the project.

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

var xml = jsonToXml(inputJSON);

// <?xml version="1.0" encoding="UTF-8"?>
// <body>
//   <entry>
//     <fullURL>abcd</fullURL>
//     <Resource>1234</Resource>
//   </entry>
//   <entry>
//     <fullURL>efgh</fullURL>
//     <Resource>5678</Resource>
//   </entry>
// </body>

replace your OBJtoXML function with

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

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 += "</" + prop + ">"; 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 += "</" + prop + ">";
                xml += "<" + prop + ">";

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

const objectToXml = (object) => Object.keys(object).reduce((reqStr, key) => {
  const value = object[key] || '';
  const isObject = typeof value === 'object';
  const isArray = Array.isArray(value);
  if (isArray) {
    return reqStr + value.reduce((accumulator, currentValue) =>
      accumulator + `<${key}>${ typeof currentValue === 'object' ? objectToXml(currentValue) : (currentValue || '')}</${key}>`
    ,'');
  }
  if (isObject) {
    return reqStr + `<${key}>${objectToXml(value)}</${key}>`;
  }
  return reqStr + `<${key}>${value}</${key}>`;
}, '');       

const output = objectToXml(yourJson);
console.log(output);
