Get only text from html with html agility

I'm trying to remove from the html everything that is concerned to html with html agility, but I need to keep the text. For example, from this tag:

<TR><TD> 
<B><A HREF="survival/index.html">Survival</A></B><BR> 
<I>Be Suspicious, Be Worried, Be Prepared</I><BR> 
<TD> 

I want to keep only "Be suspicious..."

I have this method, but doesn't work very well:

    private static HtmlDocument RemoveHTML(HtmlDocument document)
    {
        HtmlDocument textOfDoc = new HtmlDocument();
        foreach (var node in document.DocumentNode.SelectNodes(".//p|.//title|.//body"))
        {
            var newNode = HtmlNode.CreateNode(node.InnerText+" ");
    开发者_如何学编程        textOfDoc.DocumentNode.AppendChild(newNode);
        }
        return textOfDoc;
    }

THANKS!

It looks like you're only extracting P, TITLE and BODY tags. If you want I tags as well, you need to do this:

document.DocumentNode.SelectNodes(".//p|.//title|.//body|.//i")
