Not surprising, this type of statement is expected from the guilty party, in such a case silence is appreciated.

anyways, I thought why not using innerHTML/textContent combination instead of using DOMParser,
so, I ran a few tests and the performance was very close, but finally I decided that DOMParser is better for one reason I found which is:
Inserting html using innerHTML (even to an in-memory created element), image tags if any will try to fetch their src content (not sure about other tags) and this is not the case for DOMParser

Thanks Dave,
