Get Post ID as a separate RSS feed item

Question

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, 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.

How did I workaround this?

Step1: From my WordPress Permalink Settings, I selected Custom Structure and added /%post_id%/ This means my results will be in this format:

<myurl>/<postID>

Step2: To make it easier for me instead of writing a regex query I used a a Split command like this:

var postlink = entry.link;
var id = postlink.split(/\//)[3];

(///)[3] would simply split the URL by the number of slashes and take only that 3rd bit which is where my postID is.

I hope this comes in handy for others in my position.
