Extracting Inner text from HTML BODY node with Html Agility Pack

Need a bit of help with HTML Agility Pack!

Basically I want to grab plain-text withing the body node of the HTML. So far I have tried this in vb.net and it fails to return the innertext meaning no change is seen, well atleast from what I can see.

Dim htmldoc As HtmlDocument = New HtmlDocument
htmldoc.LoadHtml(html)

Dim paragraph As HtmlNodeCollection = htmldoc.DocumentNode.SelectNodes("//body")

If Not htmldoc Is Nothing Then
   For Each node In paragraph
       node.ParentNode.RemoveChild(node, True)
   Next
End If

Return htmldoc.DocumentNode.WriteContentTo

I have tried this:

Return htmldoc.DocumentNode.InnerText

But still no luck!

Any advice???

Jeff's solution is ok if you haven't tables, because text located in the table is sticking like cell1cell2cell3. To prevent this issue use this code (C# example):

var words = doc.DocumentNode?.SelectNodes("//body//text()")?.Select(x => x.InnerText);
return words != null ? string.Join(" ", words) : String.Empty;

How about:

Return htmldoc.DocumentNode.SelectSingleNode("//body").InnerText
