python爬蟲——爬取古詩名句

一. 概要

1.經過python爬蟲循環爬取古詩詞網站古詩名句
2.落地到本地數據庫

二. 頁面分析

首先經過firedebug進行頁面定位：

其次源碼定位：

最終生成lxml etree定位div標籤源碼：

response = etree.HTML(data)
for row in response.xpath('//div[@class="left"]/div[@class="sons"]/div[@class="cont"]'):
    content = row.xpath('a/text()')[0]
    origin = row.xpath('a/text()')[-1]
    self.db.add_new_row('mingJuSpider', {'content': content, 'origin': origin, 'createTime': str(date.today())})

三. 執行結果

四. 腳本源碼
