Hi,

How do you modify the code below to delete data in all files ending with Country.xml? where country will be selected from a combobox. For example filename is LinkFileUSA.xml

'' The main directory that holds all the other directories
'' Modify the directory path to fit your needs
Dim mainDirPath As String = "C:\Working Directory\temp\"
'' Get an array of directories that you will look into 
'' to modify the XML files
Dim dirs = Directory.GetDirectories(mainDirPath)

'' Iterate through all the directories
For Each thisDir In dirs
    '' Select all the XML files and modify them
    For Each xmlFile In Directory.GetFiles(thisDir, "*.xml")
        '' Open each document
        Dim xdoc As XDocument = XDocument.Load(xmlFile)
        '' Query the document and find all elements that are not "ID' = to 0
        Dim tables As List(Of XElement) = (From ele In xdoc.Descendants()
                                           Where ele.Name.LocalName.StartsWith("Table") AndAlso ele.Element("ID").Value <> "0"
                                           Select ele).ToList()

        '' Remove all unwanted elements from the main document
        tables.Remove()
        '' Save the modified file back to the file system
        xdoc.Save(xmlFile)
    Next
Next

Hi Victor,

Try the following:

Dim countryString As String = DropDownList.SelectedItem.Value

Dim mainDirPath As String = "C:\Working Directory\temp\"
Dim dirs = Directory.GetDirectories(mainDirPath)

For Each thisDir In dirs
    For Each xmlFile In Directory.GetFiles(thisDir,   "*" + countryString + ".xml")

' The rest follows your code
