Read xml in infopath using javascript

I want to read xml inside the infopath form. I am saving all infopath forms after submitting into a form library. Now I want to read the xml inside that. I am doing like following,

$(function(){
    $.ajax({
        type:"GET",
        url:"/sites/mysite/DemandRequests/DR_37.xml",
        contentType:'xml',
        success:function(xmlContent){
            console.log(xmlContent);
        },
        error:function(){
            console.log('failed');
        }
    });
});

Content is coming as pure html. I am not finding any xml init. How to read only xml?
