For most projects, is the best starting point due to its zero-dependency nature. However, if you find yourself needing advanced selection logic or processing multi-gigabyte files, switching to lxml is the logical next step. How to parse xml using python

: A minimal implementation of the Document Object Model. It is useful if you are already familiar with the DOM API from JavaScript, but it can be memory-intensive as it loads the entire document into RAM.
