javascript - parse xml response with jQuery

Question

HI all,
I use jQuery to parse my xml?responses.

I have this xml :

<?xml version="1.0" encoding="UTF-8"?>
<response status="ok">
  <client_id>185</client_id>
</response>

And i want to get "client_id" value.

To fix the expected response data type to XML right in your request, set the dataType parameter to "xml". If you don't, jQuery uses the response headers to make a guess.

It is supported on the $.ajax() function as part of the options object, as well as on $.get() and $.post():

jQuery.ajax( options )
jQuery.get( url, data, callback, type )
jQuery.post( url, data, callback, type )

So you could do this:

$.ajax({
  type: 'GET',
  url: "foo.aspx",
  data: {
    key: "value"
  },
  dataType: "xml",
  success: function (xml){
    var clientid = $(xml).find('client_id').first().text();
    alert(clientid);
  }   
});

Note that as of jQuery 1.5 you can use a nicer version of the above Ajax request:

$.get("foo.aspx", {
  key: "value"
})
.done(function (xml){
  var clientid = $(xml).find('client_id').first().text();
  alert(clientid);
});
