Nem*_*XXX 7 html python replace beautifulsoup html-parsing
我想用另一个标签替换标签,并将旧标签的内容放在新标签之前.例如:
我想改变这个:
<html>
<body>
<p>This is the <span id="1">first</span> paragraph</p>
<p>This is the <span id="2">second</span> paragraph</p>
</body>
</html>
进入这个:
<html>
<body>
<p>This is the first<sup>1</sup> paragraph</p>
<p>This is the second<sup>2</sup> paragraph</p>
</body>
</html>
我可以很容易地找到所有spans与find_all()从id属性获得的数量和更换使用另一个标签一个标签replace_with(),但我怎么用文字代替标签和新标签的更换标签之前或插入文本？
我们的想法是找到每个span带有id属性的标签(span[id] CSS Selector),用于insert_after()在sup其后插入标签并unwrap()用它的内容替换标签:
from bs4 import BeautifulSoup
data = """
<html>
<body>
<p>This is the <span id="1">first</span> paragraph</p>
<p>This is the <span id="2">second</span> paragraph</p>
</body>
</html>
"""
soup = BeautifulSoup(data)
for span in soup.select('span[id]'):
# insert sup tag after the span
sup = soup.new_tag('sup')
sup.string = span['id']
span.insert_after(sup)
# replace the span tag with it's contents
span.unwrap()
print soup
打印:
<html>
<body>
<p>This is the first<sup>1</sup> paragraph</p>
<p>This is the second<sup>2</sup> paragraph</p>
</body>
</html>
