Vil*_*ard 4 python beautifulsoup
我正在探索 BeautifulSoup 并旨在仅保留 HTML 文件中的特定标签以创建新文件。
我可以通过以下程序成功实现这一目标。但是，我相信可能有一种更合适、更自然的方法，无需手动附加字符串。
from bs4 import BeautifulSoup
#soup = BeautifulSoup(page.content, 'html.parser')
with open('P:/Test.html', 'r') as f:
contents = f.read()
soup= BeautifulSoup(contents, 'html.parser')
NewHTML = "<html><body>"
NewHTML+="\n"+str(soup.find('title'))
NewHTML+="\n"+str(soup.find('p', attrs={'class': 'm-b-0'}))
NewHTML+="\n"+str(soup.find('div', attrs={'id' :'right-col'}))
NewHTML+= "</body></html>"
with open("output1.html", "w") as file:
file.write(NewHTML)
您可以拥有所需标签的列表，迭代它们，并使用 Beautiful Soup 的追加方法有选择地在新的 HTML 结构中包含相应的元素。
from bs4 import BeautifulSoup
with open('Test.html', 'r') as f:
contents = f.read()
soup = BeautifulSoup(contents, 'html.parser')
new_html = BeautifulSoup("<html><body></body></html>", 'html.parser')
tags_to_keep = ['title', {'p': {'class': 'm-b-0'}}, {'div': {'id': 'right-col'}}]
# Iterate through the tags to keep and append them to the new HTML
for tag in tags_to_keep:
# If the tag is a string, find it in the original HTML
# and append it to the new HTML
if isinstance(tag, str):
new_html.body.append(soup.find(tag))
# If the tag is a dictionary, extract tag name and attributes,
# then find them in the original HTML and append them to the new HTML
elif isinstance(tag, dict):
tag_name = list(tag.keys())[0]
tag_attrs = tag[tag_name]
new_html.body.append(soup.find(tag_name, attrs=tag_attrs))
with open("output1.html", "w") as file:
file.write(str(new_html))
假设您有一个如下所示的 HTML 文档（为了重现性而将其包含在内会很有帮助）：
<!DOCTYPE html>
<head>
<title>Test Page</title>
</head>
<body>
<p class="m-b-0">Paragraph with class 'm-b-0'.</p>
<div id="right-col">
<p>Paragraph inside the 'right-col' div.</p>
</div>
<p>Paragraph outside the targeted tags.</p>
</body>
</html>
结果output1.html将包含以下内容：
<html>
<body>
<title>Test Page</title>
<p class="m-b-0">Paragraph with class 'm-b-0'.</p>
<div id="right-col">
<p>Paragraph inside the 'right-col' div.</p>
</div>
</body>
</html>
