I created a transform workbook and would like to write a macro to allow
the user to import different XML files. in the workbook (Excel 2007) i
issue the command under the Developer tab / XML / Import. It open a
file dialoged box, I select my file and the data is refreshed.

I searched help and do not understand the "expression.XmlImportXml
(Data, ImportMap, Overwrite, Destination)"

an you help me with an example of proper code or the correct object to
use
