python爬蟲:獲取標籤內部全部文字

取出以下字串:親測連結

我要取出text內容,怎麼取呢,很多方法,bs4也可以,正則也可以,動態selenium也可以,這次我們先實現xpath,xpath的確很強大,不多說,上程式。

通過text獲取文字

import reqiests
from lxml import etree
url = 'https://tieba.baidu.com/p/5815118868?pn=&red_tag=1075036600'
headers = {'User-Agent':'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36'}
response = requests.get(url,headers=headers).tetx
code = etree.HTML(response)
info = code.xpath('//div['//div[@class="d_post_content_main  d_post_content_firstfloor"]/div/cc/div/text()')
#/text()獲取標籤的文字   //text()獲取標籤以及子標籤的文字   
print(info)#獲取的文字還要進行美化修改

使用xpath('string(.)')獲取文字

import reqiests
from lxml import etree
url = 'https://tieba.baidu.com/p/5815118868?pn=&red_tag=1075036600'
headers = {'User-Agent':'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36'}
response = requests.get(url,headers=headers).tetx
code = etree.HTML(response)
code.xpath('//div[@class="d_post_content_main  d_post_content_firstfloor"]')
