Cross-Domain AJAX XML Reader

Question

Noobie is here. I am writing a client script that should read an XML file from another domain. I tried to use JSONP. I get a 200 response, but for some reason the client cannot access the returned data. I get two errors:

Resource interpreted as Script but transferred with MIME type text/xml 

and

 Uncaught SyntaxError: Unexpected token < 

Here's the code (I removed the XML URL as it is confidential):

 $(document).ready(function() { $.getJSON("urlOfFilecallback=?", function(data) { console.log(data) }) }); 

When I try to display data in the console, I get:

 ReferenceError: data is not defined 

How can i fix this? Do I need to use a proxy?

Answer 1

You do not need to write your own proxy. You can use YQL if you want here, for example:

 //sample site that returns xml site = 'http://goo.gl/9iQWyG'; var yql = 'http://query.yahooapis.com/v1/public/yql?q=' + encodeURIComponent('select * from xml where url="' + site + '"') + '&format=xml&callback=?'; // Request that YSQL string, and run a callback function. // Pass a defined function to prevent cache-busting. $.getJSON(yql, function(data){ console.log(data.results[0]); }); 

here is the jsfiddle check console.log.

( The limits of using the public YQL API are 2000 queries / hour on IP)

Answer 2

XML is not allowed for cross-domain requests by default.

However, with a little server programming, you can create a proxy and load the data in your own domain and output it as XML.

If you have access to the other side of the domain, you can also use this approach . Cross-domain request
