multiple XML DMEE format for one payment method

Dears,

Our requirement is to implement payment XML file through DMEE and send it to HSBC bank. We have created and configured only one payment method for different XML files format for multiple countries. I have found in the threads that this can not be possible for XML format and only if my structure tree of type text file, so we can create segment levels and grouping them and use condition to map each country for it's specified tree format. But the implementation must be an XML not a text file and also it must be of one payment method with multiple structures.

So, my query is, can we create the text file (in DMEE) with segments and conditions to map multiple countries for each structure tree, and then use the XSLT program exit to transform the file to an XML then send it to the Bank??

Thank you for your help and suggestions.
