Answer 1

You could do it like this:

Dim doc As New XmlDocument()
Dim months As IDictionary(Of String, String) = New Dictionary(Of String, String)() From {{"January", "1"}, {"February", "2"}, {"March", "3"}, {"April", "4"}, {"May", "5"}, {"June", "6"}, {"July", "7"}, {"8", "August"}, {"September", "9"}, {"October", "10"}, {"November", "11"}, {"December", "12"}}
Dim expr As New Regex([String].Join("|", months.Keys))
Dim strFile As String = "May"

doc.Load(TextBox1.Text & "\" & parentFolder & ".xml")

For Each item As XmlNode In doc.GetElementsByTagName("month")
    item.Value = expr.Replace(item.Value, Function(m) months(m.Value))
Next
