XPath(self, path, namespaces=None, extensions=None, regexp=True, smart_strings=True) A compiled XPath expression that can be called on Elements and ElementTrees.

Besides the XPath expression, you can pass prefix-namespace mappings and extension functions to the constructor through the keyword arguments `namespaces` and `extensions`. EXSLT regular expression support can be disabled with the 'regexp' boolean keyword (defaults to True). Smart strings will be returned for string results unless you pass `smart_strings=False`.
