A Lua XPath library based on libxml2. It provides easy-to-use APIs inspired by Scrapy's selector classes.
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
