XmlDoc.DocumentElement("ctry").InnerText =
string.Join(",", XmlDoc.DocumentElement("ctry").InnerText.Split(',').Distinct().ToArray());
not sure how you are parsing the xml but the idea is as ollows
dim duplicateString as string
duplicateString= "BEL,BEL,GRC,GRC,USA";

Dim cleanString as string = string.Join(",", duplicateString.Split(',').Distinct().ToArray())

Hi Victor;

Thsi code snippet should give you what you need.

Dim inputXML As String = "File path and name"
Dim saveXML As String = "File path and name"
'' Load the XML document
Dim xdoc = XDocument.Load(inputXML)

Dim results As List(Of XElement) = (From n In xdoc.Descendants("ctry") _
                                    Select n).ToList()
For Each node As XElement In results 
    Dim values As List(Of String) = node.Value.Split(New char() {","c}).Distinct().ToList()
    node.Value = String.Join(",", values)
