 }

function validate_ext() {
var filename = document.getElementById("file1").value;
var filename2 = document.getElementById("file2").value;
var ext = getExt(filename);
var ext2 = getExt(filename2);

    if (!(ext == "xml")) {
       alert("Please upload XML file format only");
       return false;
    }

Answer 1

i did mistake following line

if (filename != "") {
if (!(ext == "xml")) {
   alert("Please upload XML file format only");
   return false;
   }
}

if (filename2 != "") {
if (!((ext2 == "jpg") || (ext2 == "jpeg") || (ext2 == "png"))) {
        alert("Please upload jpg, jpeg, png file format only");
        return false;
    }
}

and but after change now it’s working

if (!(ext == "xml")) {
   alert("Please upload XML file format only");
   return false;
}


if (!((ext2 == "jpg") || (ext2 == "jpeg") || (ext2 == "png"))) {
        alert("Please upload jpg, jpeg, png file format only");
        return false;
    }

here is working code http://jsfiddle.net/vikastyagi87/XugLp/29/
