result = resp_xpath.xpath('//*[@id="novel4451"]/dl/dd/a/@href')
for i in range(0,4):
url1 ='https://www.soxscc.com/' +result[i]
print(url1)
输出结果是
因为设置只循环四次,从第一章节循环到第四章网址
for i in range(0,4):
url1 ='https://www.soxscc.com/' +result[i]
print(url1)
用xpath方便了很多,这次只需要在网页检查的页面点击复制xpath
之后
result = resp_xpath.xpath('//*[@id="novel4451"]/dl/dd/a/@href')
就得到了href列表result,添加一些代码打印出来
for i in result:
print()
方便多了。。。
之后就更简单了,只用了3次for循环,而且不复杂

这次可以指定下载多少章节,10次循环下载10章节
下次爬取网抑云音乐评论。。。
假如获得了网页的字符串格式,也就是上面的resp.text,用etree可以把它变成xpath的格式,也就是说可以用.xpath()这个函数,括号里面写要爬取的东西的xpath,直接在网页源代码里复制就行了。有时候复制了也爬取不了。
/@href就是取出标签a里的那一段地址
如果是/text()的话,会出现文字信息。
.format()的作用就是把括号里的东西填入{}中去
比如
得到
