Try this:

JavaScript

var employees = $(xmfile).find("employee[id=20]");
if(employees.length == 1) {
    var employee = employees[0];
    var name = $(employee).find("name").text();
    alert(name);
}
else if (employees.length == 0) {
    alert("No employees found with that ID.");
}
else { // in this case, employees.length > 1
    alert("Too many employees found with that ID.");
}

How it works: it finds all employees with 20 as ID and stores them in an array. If the length of that array is one, it stores the only item in the variable employee, looks for the element name, and stores the inner text in the variable name.
