question on moving hard coded values to XML need input

Question

Hi all,

I need to move all hard coded keys and values to a common place so that we can avoid inconsistency and code changes for hard codings.

This work is in perl, so using XML or using a module in perl would be good?

And also what is the best way to define tags in XML or any suggestions for best way of doing such things is what i am interested.

Thanks,
