And indeed, any CSS selector can be converted to an equivalent XPath query, at least for selectors on XML and HTML. http://pythonhosted.org/cssselect/ is a Python implementation of such a conversion. (Note that there is no XPath to CSS selector converter, as XPath can express certain things CSS selectors cannot, as CSS selectors are designed such that they can be matched using a streaming parser as soon as the first child of the element appears.)
