I'm actually more concerned about DOM manipulation and parsing-activities in comparison to creating an object and method invocations. I understand there's a lot of overlap and instantiating objects is inherent to both, and maybe I need to dig through parser code and see how it's working and what's getting created. My thinking was that it could *potentially* be an issue.
