Python BeautifulSoup将HTML解析为一行字符串
出于某种原因，当我使用beautifulsoup解析HTML页面并将页面打印到txt文件时，它会取消HTML格式并将其放在一行上。当我尝试使用正则表达式搜索时，它会找到一些东西，然后打印出行，但是这会打印出整个页面，因为它都是一行。。。我怎样才能让它停止这样做 这是我的密码：Python BeautifulSoup将HTML解析为一行字符串,python,html,web-scraping,beautifulsoup,Python,Html,Web Scraping,Beautifulsoup,出于某种原因，当我使用beautifulsoup解析HTML页面并将页面打印到txt文件时，它会取消HTML格式并将其放在一行上。当我尝试使用正则表达式搜索时，它会找到一些东西，然后打印出行，但是这会打印出整个页面，因为它都是一行。。。我怎样才能让它停止这样做 这是我的密码： #!/usr/bin/python3 from bs4 import BeautifulSoup import re import urllib.request def main(): #Open the P

如果你能帮忙，那太好了。。。我试过各种方法，从粉饰到尝试自己把它分成几行，但似乎没有一种方法是正确的。我想它是一样的源代码格式，以便我可以很容易地搜索和获得我需要的项目从它！谢谢你的帮助，如果可以的话，不要只是给我一个答案，你也能解释一下你做了什么吗 我尝试了这个简单的脚本来提取
NetDepthfrom bs4 import BeautifulSoup as bs
from urllib import urlopen
soup = bs(urlopen('<insert url here>').read())
print soup.find(id="ProductNetDepth").next_sibling.next_sibling.div.text
从bs4导入美化组作为bs
从urllib导入urlopen
soup=bs（urlopen（“”）.read（））
打印soup.find（id=“ProductNetDepth”）.next\u sibling.next\u sibling.div.text
如果您不熟悉soup的搜索功能，那么您应该会看到它们写得非常好。我尝试了这个简单的脚本来提取
