Python

Question

我有一个名为 BBC_news_home.html 的文件，我需要删除所有标记标签，这样我剩下的只是一些文本。到目前为止我得到了：

def clean_html(html):
    cleaned = ''

line = html

pattern = r'(<.*?>)'

result = re.findall(pattern, line, re.S)

if result:
    f = codecs.open("BBC_news_home.html", 'r', 'utf-8')
    print(f.read())
else:
    print('Not cleaned.')
return cleaned

我已经与 regex101.com 确认模式是正确的我只是不确定如何打印输出以检查标记标签是否消失了？

你真的应该为此使用 BeautifulSoup。根据您需要的 python 版本执行 pip3 install BeautifulSoup4 或 pip install BeautifulSoup4。我已经发布了一个类似问题的答案。为了完整起见：

from bs4 import BeautifulSoup

def cleanme(html):
    soup = BeautifulSoup(html) # create a new bs4 object from the html data loaded
    for script in soup(["script"]): 
        script.extract()
    text = soup.get_text()
    return text
testhtml = "<!DOCTYPE HTML>\n<head>\n<title>THIS IS AN EXAMPLE </title><style>.call {font-family:Arial;}</style><script>getit</script><body>I need this text captured<h1>And this</h1></body>"

cleaned = cleanme(testhtml)
print (cleaned)

结果的输出仅为I need this text captured And this。

Python - 删除标记并从文件中读取 html？

Python - remove markup tags and read html from the file?
