I'm pretty new to all this stuff, so please excuse my ignorance. I have created a webpage in html and designed it with CSS. It is mainly a blog, so I want an RSS feed for it. I created an xml file and submitted it to feedburner, but all that shows up in the feed is the title and description and link to the page. How do I get the full content of my post to show up?

Here is my xml file (edited to just one item)
Code:
<?xml version="1.0" encoding="ISO-8859-1" ?>
	<rss version="2.0">
	<channel>
		<title>Sew Whitney</title>
		<link>http://www.sewwhitney.com/</link>
		<description>A sewing and crafting blog</description>
	
	<item>
		<title>Under Construction</title>
		<guid>http://www.sewwhitney.com/2012/08/02/under-construction/</guid>
		<pubDate>Thursday, August 2, 2012</pubdate>
		<description>Site is under construction.</description>

And here is the html file for one page

<h1>Under Construction</h1>
<h2>Aug 2<br>2012</h2>

<p>So I'm coming back!  I know I've been gone for almost a year, and the site is
obviously a mess, but I'm working on the new design.  I'll have it up and running
as soon as possible.  For now, all my old posts are still here, minus photos and 
links for now.  But that will all change soon.</p>
