As you have attached a screenshot of your Object data then you can use Array.prototype.shift() to remove the first entry in the array:

var array = [];
var data = $.xml2json(xml)['#document'];
array = data.contact.name.shift(); // <----this will remove the first entry in the array.

a sample demo:

var array = [];
var data = {
  contact: {
    name: [{
      name: "one"
    }, {
      name: "two"
    }, {
      name: "three"
    }]
  }
};
array = data.contact.name.shift(); // <----this will remove the first entry in the array.
document.querySelector('pre').innerHTML = JSON.stringify(data, 0, 3);

<pre></pre>

Find the index of the element you want to remove (using indexOf) and then use splice to remove it....

var idx = that.array.indexOf(theIndexyouWantToRemove);
that.array.splice(idx, 1);

If its definitely the first element always, then you could use shift().
