JavaScript / jQuery parse xml

Question

I wanted to get like count numbers from this link

http://api.facebook.com/restserver.php?method=links.getStats&urls=http://www.apple.com

var xml = "http://api.facebook.com/restserver.php?method=links.getStats&urls=http://www.apple.com;"
var xmlDoc = $.parseXML(xml),
$xml = $(xmlDoc),
$title = $xml.find( "like_count" );
$('.countnumber').text($title.text());

however, I got this error

Uncaught Error: Invalid XML: http://api.facebook.com/restserver.php?method=links.getStats&urls=http://www.apple.com;

Is there a way to parse it by javascript?

Thanks

You have to get your xml first, you're only giving jquery a link to an xml document — megawac

because the contents of xml is not a xml value.. it is a url... you need to read the contents of the url first — Arun P Johny

In your case xml contains a resource url, not a xml string that is the cause of the error. You need to read the contents of the url first then parse it.

You need to read the contents of the URL

var xml = "http://api.facebook.com/restserver.php?method=links.getStats&urls=http://www.apple.com;"
$.get(xml).done(function(xml){
    var $xml = $(xml),
        $title = $xml.find( "like_count" );
    console.log($title.text())
})

Demo: Fiddle

As mentioned in the comments retrieve your xml first.

$.ajax({
    url: "http://api.facebook.com/restserver.php?method=links.getStats&urls=http://www.apple.com;",
    dataType: "xml"
}).done(function(data) {
    var $xml = $(data),
        $title = $xml.find("like_count");
    $('.countnumber').text($title.text());
});

You need a string representing your xml, not the URI to the resource. Also, parseXML isn't even neccessary.

You need to use AJAX to get the XML:

    var xml = "http://api.facebook.com/restserver.php?       method=links.getStats&urls=http://www.apple.com;";

    $.get(xml, function(data){
      var xmlDoc = $(data);
      .. your code here
    });
