Solution

Try the following code. It should fetch you all the values you are after.

Sub XML_Parsing_ano()
    Dim http As New XMLHTTP60
    Dim xmldoc As Object, post As Object

    With http
        .Open "GET", "http://antt.vn/rss/trang-chu.rss", False
        .send
        Set xmldoc = CreateObject("MSXML2.DOMDocument")
        xmldoc.LoadXML .responseXML.XML
    End With

     For Each post In xmldoc.SelectNodes("//item")
        r = r + 1: Cells(r, 1) = post.SelectNodes(".//title")(0).Text
        Cells(r, 2) = post.SelectNodes(".//pubDate")(0).Text
        Cells(r, 3) = post.SelectNodes(".//link")(0).Text
    Next post
End Sub

Or, If you wanna stick to .getElementsByTagName() then:

Sub XML_Parsing_ano()
    Dim http As New XMLHTTP60
    Dim xmldoc As Object, post As Object

    With http
        .Open "GET", "http://antt.vn/rss/trang-chu.rss", False
        .send
        Set xmldoc = CreateObject("MSXML2.DOMDocument")
        xmldoc.LoadXML .responseXML.XML
    End With

     For Each post In xmldoc.getElementsByTagName("item")
        r = r + 1: Cells(r, 1) = post.getElementsByTagName("title")(0).Text
        Cells(r, 2) = post.getElementsByTagName("pubDate")(0).Text
        Cells(r, 3) = post.getElementsByTagName("link")(0).Text
    Next post
End Sub
