How do I add CDATA to an xml file?
<contents>
  <item>
    <![CDATA[
        <a style="font-weight: bold;" href="http://engadget.com">Engadget</a>
    ]]>
  </item>
  <item>
    <![CDATA[
        <a style="font-weight: bold;" href="http://cnn.com">CNN</a>
    ]]>
  </item>
</contents>

foreach (string s in notifications)
        {
            XmlElement newElement = doc.CreateElement("item");
            newElement.InnerXml = "<![CDATA[ " + s + " ]]>";
            doc.DocumentElement.SelectNodes("/contents")[0].AppendChild(newElement);
        }

newElement.InnerXml = "<![CDATA[ " + s + " ]]>";

newElement.AppendChild(doc.CreateCDataSection(s));

newElement.InnerXml = "<![CDATA[ " + s + " ]]>";
