Just fetch the XmlCDataSection and change the Value property. Here's an example which admittedly uses LINQ to find the CData section, but the principle of changing it would be the same:

using System;
using System.Linq;
using System.Xml;

class Test
{
    static void Main(string[] args)
    {
        string xml = 
@"<elements>
    <![CDATA[-div[id|dir|class|align|style],-span[class|align]]]>
</elements>";
        XmlDocument doc = new XmlDocument();
        doc.LoadXml(xml);
        XmlCDataSection cdata = doc.DocumentElement
                                   .ChildNodes
                                   .OfType<XmlCDataSection>()
                                   .First();
        cdata.Value = "-div[id|dir|class|align|style],-span[class|align|style]";
        doc.Save(Console.Out);
    }
}
