What's the difference between responseText and responseXML?

when I get response from a jsp file, alert(ajax.responseText) ,it shows:

<?xml version="1.0" encoding="utf-8"?>
<employees>
    <employee name="J.Doe">
        <job>Programmer</job>
        <salary>32768</salary>
    </employee>
    <employee name="A.Baker">
        <job>Sales</job>
        <salary>70000</salary>
    </employee>
    <employee name="Big Cheese">
        <job>CEO</job>
        <salary>100000</salary>
    </employee>
</employees>

while use alert(ajax.responseXML), it shows [object].

the point is that I need retrieve certain data in this XML, that is how to handle xmlObj = ajax.responseXML?
xmlObj.getELementsByTagName("employee")[0].firstChild.data does not work.

I found Microsoft.XMLDOM object can load (not open) an xml file into an xmlObj,which can be handle like xmlObj.getELementsByTagName("employee")[0].firstChild.data .

So what is the difference between XMLDOM and XMLHTTP?

Yep, you'll want to use ajax.responseXML then. It returns a XML object that can be parsed using standard DOM methods. In the case of:

<?xml version="1.0" encoding="utf-8"?>
<employees>
    <employee name="J.Doe">
        <job>Programmer</job>
        <salary>32768</salary>
    </employee>
    <employee name="A.Baker">
        <job>Sales</job>
        <salary>70000</salary>
    </employee>
    <employee name="Big Cheese">
        <job>CEO</job>
        <salary>100000</salary>
    </employee>
</employees>

You can get to the first employee's salary by doing something like:

var xmlobj=ajax.responseXML
var DoeSalary=xmlobj.getElementsByTagName("employee")[0].childNodes[1].nodeValue
