    Title string `xpath:"//h1"`
    Files []string `xpath:".//table[contains(concat(' ',normalize-space(@class),' '),' files ')]//tbody//tr[contains(concat(' ',normalize-space(@class),' '),' js-navigation-item ')]//td[contains(concat(' ',normalize-space(@class),' '),' content ')]"`

func main() {
    res, err := http.Get("https://github.com/azlotnikov/goxtag")
