If you want to rename files recusivelly using linux find command, here are two example usage of it with exec and xargs. This command will convert all the *.xml files into *.html files.

Using xags

find . | xargs rename 's/\.xml$/\.html/i'

Using exec

find . -exec rename 's/\.xml$/\.html/i' {} +

find . -prune -exec rename 's/\.xml$/\.html/i' {} +
