When I do a request in 'xml' mode with the code:

options = jQuery.extend({

url: null,

data: null,

success: null

}, options);

if(options.url) {

$.ajax({

type: 'GET',

url: options.url,

data: options.data,

dataType: 'xml',

success: function(xml) {

var feed = new JFeed(xml);

if(jQuery.isFunction(options.success)) options.success(feed);

}

});

}

using a ATOM feed url, the IE8 cannot parse it, then, I added the following code at line 5346:

httpData: function( xhr, type, s ) {

var ct = xhr.getResponseHeader("content-type") || "",

xml = type === "xml" || !type && ct.indexOf("xml") >= 0,

data = xml ? xhr.responseXML : xhr.responseText;

>>>> My changes

if (xml && !data.documentElement && xhr.responseText)

data.loadXML(xhr.responseText);

<<<< ended my changes

if ( xml && data.documentElement.nodeName === "parsererror" ) {

jQuery.error( "parsererror" );

}
