Xpath (normalize space)

Im using HtmlAgilityPack and Xpath to retrieve some text from a webpage. My problem is that the it retrieves all the whitespaces aswell. I need some help using the "fn:normalize-space(string)" function to normalize the retrieved text.

Code:

---

        Dim content2 As String = ""
        Dim web2 As New HtmlAgilityPack.HtmlWeb
        Dim doc2 As HtmlAgilityPack.HtmlDocument = web2.Load("http://www.yellowpages.ca/search/si/1/Estheticians/Calgary+AB ")
        Dim hnc2 As HtmlAgilityPack.HtmlNodeCollection = doc2.DocumentNode.SelectNodes("//div[@class='address']")
        For Each link As HtmlAgilityPack.HtmlNode In hnc2
            Dim replaceUnwanted As String = ""
            replaceUnwanted = link.InnerText.Replace("&", "&") '
            replaceUnwanted = replaceUnwanted.Replace("'", "'")

            content2 &= replaceUnwanted & vbNewLine
        Next
        RichTextBox2.Text = content2
