Question

I would like to retrieve fullpath of a file and pass it to javascript. The requirement is that I need to retrieve XML file using JavaScript.

Answer 1

If it is a file you can access relatively to your web page do something like:

var xmlDoc=new ActiveXObject("MSXML.DOMDocument");
xmlDoc.async="false";
xmlDoc.load("abc.xml"); 

Assuming you have your web page next to the abc.xml…

This doesn’t specify how to get full path to the XML – do youi still need it or loading it is enough?

For cross browser (from: http://developer.apple.com/internet/webcontent/xmlhttpreq.html)

var req;
loadXMLDoc("abc.xml");

function loadXMLDoc(url) {
    req = false;
    // branch for native XMLHttpRequest object
    if(window.XMLHttpRequest && !(window.ActiveXObject)) {
    try {
                req = new XMLHttpRequest();
            } catch(e) {
                req = false;
            }
        // branch for IE/Windows ActiveX version
        } else if(window.ActiveXObject) {
            try {
                req = new ActiveXObject("Msxml2.XMLHTTP");
            } catch(e) {
                try {
                    req = new ActiveXObject("Microsoft.XMLHTTP");
                } catch(e) {
                    req = false;
                }
            }
        }
        if(req) {
            req.onreadystatechange = processReqChange;
            req.open("GET", url, true);
            req.send("");
        }
    }

    function processReqChange() {
        // only if req shows "loaded"
        if (req.readyState == 4) {
            // only if "OK"
            if (req.status == 200) {
                // ...processing statements go here...
                alert(req.responseXML);
            } else {
                alert("There was a problem retrieving the XML data:\n" + req.statusText);
            }
        }
    }
