XML Node text and UDT buffer string...!!!

[Wokawidget]

OK I have:

Public Type gtypStructureProps
    IsNew           As Boolean
    IsDirty         As Boolean
    IsDeleted       As Boolean
    Key             As String * 36
    ID              As Long
    Description     As String * 30
End Type
 
Public Type gtypStructureData
    Data            As String * 72
End Type

Which are the UDTs for my table tblStructures...
Now, in the load event I have:

Set adoRec = New Recordset
    With adoRec
        .Open strSQL, DB_CONN, adOpenForwardOnly, adLockReadOnly
        Do While Not .EOF
        
            Set objRoot = objDOM.createElement("Structure")
            
            udtProps.ID = .Fields("ID").Value
            udtProps.Description = .Fields("Description").Value
            udtProps.Key = vbNullString
            udtProps.IsNew = False
            udtProps.IsDirty = False
            udtProps.IsDeleted = False
            LSet udtData = udtProps
                    
            Set objProp = objDOM.createElement("UDT")
            objProp.Text = "Q" & udtData.Data & "P"
            Debug.Print objProp.Text
            Debug.Print udtData.Data
            objRoot.appendChild objProp
            Set objProp = Nothing

My udtData.Data is a string and contains the data from the props UDT, and the debug.print statement proves that it contains the correct data...HOWEVER! When I assign this string to the text property of an XML node all the data vanishes!!!
The debug.Print objProp.Text just prints "Q" to the immediate window...the trailing "P" AND all the data vanishes!!!
Is there something up with XML that stops me doing this???
