我有下面的脚本,它修改HTML文件中的href
属性(将来,它将是目录中的HTML文件列表)。使用BeautifulSoup我设法访问标记值并按我的意愿修改它们,但我不知道如何保存对文件所做的更改。
import os
import re
from bs4 import BeautifulSoup
htmlDoc = open('adding_computer_c.html',"r+")
soup = BeautifulSoup(htmlDoc)
replacements= [ ('_', '-'), ('../tasks/', prefixUrl), ('../concepts/', prefixUrl) ]
for link in soup.findAll('a', attrs={'href': re.compile("../")}):
newlink=str(link)
for k, v in replacements:
newlink = newlink.replace(k, v)
extrachars=newlink[newlink.find("."):newlink.find(">")]
newlink=newlink.replace(extrachars,'')
link=newlink
print(link)
##How do I save the link I have modified back to the HTML file?
print(soup)##prints the original html tree
htmlDoc.close()
答案 0 :(得分:37)
newlink = link['href']
# .. make replacements
link['href'] = newlink # store it back
现在print(soup.prettify())
将显示已更改的链接。要将更改保存到文件:
htmlDoc.close()
html = soup.prettify("utf-8")
with open("output.html", "wb") as file:
file.write(html)
要保留文档的原始字符编码,可以使用soup.original_encoding
代替“utf-8”。请参阅Encodings。
