Hello.

I use the code, and have sucess:

Private Sub btnGravar_Click(ByVal sender As System.Object, ByVal e As 
System.EventArgs) Handles btnGravar.Click
 Dim doc As New XmlDocument
 Dim nodeList As XmlNodeList

 doc.Load(Server.MapPath("mainscreen.xml"))

 nodeList = doc.GetElementsByTagName("MAINNEWS")

 If (txtHeadline.Text <> "") Then
  nodeList.Item(0).ChildNodes.ItemOf(0).InnerText = txtHeadline.Text
 End If

 If (txtText.Text <> "") Then
  nodeList.Item(0).ChildNodes.ItemOf(1).InnerText = 
ReplaceWriteChars(txtText.Text)
 End If

 If (txtImageUrl.Text <> "") Then
  nodeList.Item(0).ChildNodes.ItemOf(2).InnerText = txtImageUrl.Text
 End If

 If (txtImageCaption.Text <> "") Then
  nodeList.Item(0).ChildNodes.ItemOf(3).InnerText = txtImageCaption.Text
 Else
  nodeList.Item(0).ChildNodes.ItemOf(3).InnerText = "&nbsp;"
 End If
 doc.Save(Server.MapPath("mainscreen.xml"))
End Sub


I have another problem. When save the update information with the Save 
method, the characters, example &#60; (<) are replaced by the &amp;#60; . 
Who can I solve this problem?

Best regards.

Ricardo Fonseca
