Script Object: Replacing xpath xpressions in a template

I found this very useful post about an easy way of replacing xpath expressions in a template

I found this especially useful since I've been involved in a few projects that required us to create html templates that had dynamic values in them. Rather than having to create a custom component to do the mapping and replacing, I'm able to use this simple snippet of code in a script object.
