You are right. The approach that SeeThrough uses is the following:

apply_template(File, Env) ->
     {Tree, _Misc} = xmerl_scan:file(File),
     xmerl:export_simple(
       [visit(Tree, Env)], xmerl_xml).

There's nothing to say that the template cannot be pre-scanned and  
saved once, followed by multiple applications of xmerl:export_simple.

I'm still wondering if any performance optimizations have gone into  
xmerl in the past two years. Anyone?

	Thanks, Joel
