responseXML is returning null

Question

I am trying to parse xml data with javascript in ajax call.But responseXML is returning null value.Here is my code

<script language="javascript">
if(window.addEventListener)
{
    window.addEventListener("load",getXML,false);
}
else if(window.attachEvent)
{
    window.attachEvent("onload",getXML);
}
function getXML()
{
    var xhr = new XMLHttpRequest();
    xhr.open("GET","myxml.xml",true);
    xhr.onreadystatechange = function()
    {
        if(xhr.readyState == 4)
        {
            //alert("got response");
            var root = xhr.responseXML;
            alert(root);
        }
    }
    xhr.send(null);
}
</script>

Here is my "myxml.xml" file

<?xml version="1.0" encoding="iso-8859-1"?>
<root>
    <child-1>
        <grandChild1_1>textOfGrandChild1_1</grandchild1_1>
        <grandChild2_1>textOfGrandChild2_1</grandchild2_1>
        <grandChild3_1>textOfGrandChild3_1</grandchild3_1>
    </child-1>
    <child-2>
        <grandChild1_2>textOfGrandChild1_2</grandchild1_2>
        <grandChild2_2>textOfGrandChild2_2</grandchild2_2>
        <grandChild3_2>textOfGrandChild3_2</grandchild3_2>
    </child-2>
    <child-3>
        <grandChild1_3>textOfGrandChild1_3</grandchild1_3>
        <grandChild2_3>textOfGrandChild2_3</grandchild2_3>
        <grandChild3_3>textOfGrandChild3_3</grandchild3_3>
    </child-3>
</root>

When I tried with

alert(xhr.responseText)

it showed the xml file as it is.But when using responseXML it is giving null value.Where is the problem?

i think it is.i gave my xml file,can you tell me if there is any wrong in that xml file — Siva Charan, Apr 10 '15 at 18:28

Your XML was incorrect, beacuse it is case sensitive, changed grandchild1_1 to grandChild1_1 and it worked.

<?xml version="1.0" encoding="iso-8859-1"?>
<root>
<child-1>
    <grandChild1_1>textOfGrandChild1_1</grandChild1_1>
    <grandChild2_1>textOfGrandChild2_1</grandChild2_1>
    <grandChild3_1>textOfGrandChild3_1</grandChild3_1>
</child-1>
<child-2>
    <grandChild1_2>textOfGrandChild1_2</grandChild1_2>
    <grandChild2_2>textOfGrandChild2_2</grandChild2_2>
    <grandChild3_2>textOfGrandChild3_2</grandChild3_2>
</child-2>
<child-3>
    <grandChild1_3>textOfGrandChild1_3</grandChild1_3>
    <grandChild2_3>textOfGrandChild2_3</grandChild2_3>
    <grandChild3_3>textOfGrandChild3_3</grandChild3_3>
</child-3>

Here is the Plunker

Thanks!

Your XML is invalid, Case matters

 <grandChild1_1>textOfGrandChild1_1</grandchild1_1>
       ^                                  ^

All the closing tags have the wrong camel case in the names.

You should say his XML is [*not well-formed* rather than *invalid*](http://stackoverflow.com/a/25830482/290085). – kjhughes Apr 10 '15 at 18:55
