BRE

I’m talking about the non-BRE format. This XML are predefined by Customer containing set of rules.
The sample XML file below contains only few rules. It will be great if there is any way to convert XML file into BRE format XML programatically.
The sample XML file is as follows which contains some rules:

<?xml version=”1.0″?>
