The parsing techniques I k

Answer 1

lxml was written on C. And if you use x86 it is best chose. If we speak about techniques there is no big difference between Xpath and DOM - it's very quickly methods. But if you will use find or findAll in BeautifulSoup it will be slow than other. BeautifulSoup was written on Python. This lib needs a lot of memory for parse any data and, of course, it use standard search methods from python libs.
