rendering html content from umbraco

I am calling a web api service that takes a textpage from umbraco(cms) and displays it's associated xml in a literal control. I am getting odd html output when comparing source versus a httpwebrequest.

I use this code in a page load to call the service

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://111.111.111.111:8080/api/PageContentApi?id=1122");
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            if (response.StatusCode == HttpStatusCode.OK)
            {
                Stream stream = response.GetResponseStream();
                using (StreamReader reader = new StreamReader(stream))
                {
                    string html = reader.ReadToEnd();
                    aboutText.Text = html;
                }
            }

The string information I receive is:

[{"Id":1122,"Name":"sample","Alias":"bodyText","Value":"<p>This is a sample test</p>\r\n<p> </p>\r\n<p>two returns</p>\r\n<p> </p>\r\n<p>one return</p>\r\n<p>     spaces   spaces  <strong>bold  </strong><em> italic   </em><span style=\"text-decoration: underline;\">underline</span></p>\r\n<p> </p>\r\n<p><img width=\"201\" height=\"75\" src=\"http://111.111.111.111/media/1001/logo.gif\" alt=\"logo\"/></p>","Version":"b8cbd32e-b946-4b1f-ae72-2564b7757479","Created":"1/1/0001 12:00:00 AM","ParentId":-1}]

When I manually view the source in firefox after doing a get I see something completely different:

<ArrayOfPageContent xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/name.Models"><PageContent><Alias>bodyText</Alias><Created>1/1/0001 12:00:00 AM</Created><Id>1122</Id><Name>sample</Name><ParentId>-1</ParentId><Value>&lt;p&gt;This is a sample test&lt;/p&gt;
&lt;p&gt; &lt;/p&gt;
&lt;p&gt;two returns&lt;/p&gt;
&lt;p&gt; &lt;/p&gt;
&lt;p&gt;one return&lt;/p&gt;
&lt;p&gt;     spaces   spaces  &lt;strong&gt;bold  &lt;/strong&gt;&lt;em&gt; italic   &lt;/em&gt;&lt;span style="text-decoration: underline;"&gt;underline&lt;/span&gt;&lt;/p&gt;
&lt;p&gt; &lt;/p&gt;
&lt;p&gt;&lt;img width="201" height="75" src="http://111.111.111.111/media/1001/logo.gif" alt="logo"/&gt;&lt;/p&gt;</Value><Version>b8cbd32e-b946-4b1f-ae72-2564b7757479</Version></PageContent></ArrayOfPageContent>

why am I seeing different types of responses and what is the best way to render this content grabbed from umbraco to a asp web page.
