for i in range(1, 20):
            book_name = tree.xpath("/html/body/div[2]/div[2]/div[2]/div[3]/div[' + i + ']/@bookname")[i]
            book_writer = tree.xpath("/html/body/div[2]/div[2]/div[2]/div[3]/div[' + i + ']/div[2]/div[2]/@title")[i]
            book_type = tree.xpath("/html/body/div[2]/div[2]/div[2]/div[3]/div[' + i + ']/div[2]/div[2]/a[2]/text()")[i]
            book_plan = tree.xpath("/html/body/div[2]/div[2]/div[2]/div[3]/div[' + i + ']/div[2]/div[2]/a[3]/text()")[i]
            book_time = tree.xpath("/html/body/div[2]/div[2]/div[2]/div[3]/div[' + i + ']/div[2]/div[4]/span/text()")[i]
            book_ticket = tree.xpath("/html/body/div[2]/div[2]/div[2]/div[3]/div[' + i + ']/div[3]/div/div[2]/text()")[i]
