lua-xpath
=========

A Lua XPath library based on libxml2. It provides easy-to-use APIs inspired
by [Scrapy](http://www.scrapy.org/)'s selector classes.

Examples
--------

local xpath = require("xpath")

-- load data from file
    selector = xpath.loadfile(html)
    -- load data from string
    selector = xpath.loads("<html></html>")

------------------ OOP style ----------------------------

items = selector:xpath("//div[@name='shit']")

for k, v in ipairs(items) do
        print(v:extract())
    end

------------------ general lua style --------------------

items = xpath.select(selector, "//div[@name='shit']")

for k, v in ipairs(items) do
        print(xpath.extract(v))
    end
