I am looking for a way to display or echo each post ID within my RSS feed. Basically when I access [my RSS feed site](http://howtodeployit.com/category/daily-devotion/feed/), I get the following XML items: `<title>`, `<link>`, `<comments>`, `<category>`, `<pubDate>`, `<guid isPermaLink>`, `<description>`.

When I use this Google function in my code

    var url = 'http://howtodeployit.com/category/daily-devotion/feed/';
    		$.ajax({
    		type: "GET",
    		url: document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=1000&callback=?&q=' + encodeURIComponent(url),
    		dataType: 'json',

the returned Objects are title, link, author, publishedDate, contentSnippet...

What I also want returned is the Post ID but not sure how to get my WordPress to include that in the XML.
