Get resolved SPUser IDs from Sharepoint 2010 PeoplePicker - sharepoint-2010

Question

I try to get selected user IDs from people picker control as below:
function GetUserIdsFromPP() {
var xml = _picker.find('div#divEntityData');
var visiblefor = new Array();
xml.each(function (i, row) {
var data = $(this).children().first('div').attr('data');
var xmlDoc;
if (window.DOMParser) {
parser = new DOMParser();
xmlDoc = parser.parseFromString(data, "text/xml");
}
else // Internet Explorer
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.loadXML(data);
}
var uid = xmlDoc.getElementsByTagName('Value')[0].firstChild.nodeValue;
visiblefor.push(uid);
});
return visiblefor;
}
The problem is that sometimes XML doesn't contain <Key>SPUserID</Key><Value>1</Value> and I get FQUN (user login with domain name).
What is the better way to resolve selected SPUserIds from PeoplePicker control?

This is how resolve emails from people picker control on client side
function GetEmailsFromPicker() {
var xml = _picker.find('div#divEntityData');
var result = new Array();
xml.each(function (i, row) {
var data = $(this).children().first('div').attr('data');
var xmlDoc;
if (window.DOMParser) {
parser = new DOMParser();
xmlDoc = parser.parseFromString(data, "text/xml");
}
else // Internet Explorer
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.loadXML(data);
}
var emailIndex = -1;
for (var i = 0; i < xmlDoc.childNodes[0].childNodes.length; i++) {
var element = xmlDoc.childNodes[0].childNodes[i];
var key = element.childNodes[0].childNodes[0].nodeValue;
if (key == 'Email') {
var uid = xmlDoc.childNodes[0].childNodes[i].childNodes[1].childNodes[0].nodeValue;
result.push({ EMail: uid });
break;
}
}
});
return result;
}

Use the above answer, but...
Replace this with an appropriate Jquery or Javascript element name.
var xml = _picker.find('div#divEntityData');
