Edit, mdoify, save, and send email XML file using XSLT in the simplest way

Developers, I need to have the simplest process that can be easily modified if there are some changes in format or data. If you are using .NET then it must be VB.NET in VS 2003 (Mandatory). If we do not use programming application, can we change XSL file to perfom : edit, delete, insert, save, and send email (using button) directly? Please see the sample attachment (Click on XML file to view). 1. How to add feature to edit, modify, DELETE and INSERT line for current data, save XML, and send email the XML file using .XSL? Any modification needed for that XSL? 2. How to design the simplest process that we can modify easily if the data and XSL file are changed from this format to another format. Thanks
