This is not just an XML related question, but a common one. I don&#039;t know where to ask. I will describe the problem:-<BR> Some financial data is daily getting posted on some range of Excel sheets in various foreign countries. We have to get that information in a server in the US. Can we convert this Excel range to XML data islands and transfer the data from the client computers to our server or is it better to send the .xls files directly? We cannot implement lot of mechanism on the client computers since they range from Win &#039;95, &#039;98 through NT(I hope we can use some ActiveX DLLs). If we are able to send XML data islands, how we can implement security? We also have to do some realtime currency conversions. If you know how to do that, please advice me. If you have any doubts regarding my issue, please ask me.
