Question

我将如何编写一个函数（使用BeautifulSoup或其他函数）来替换一个HTML标记的所有实例。例如：

text = "<p>this is some text<p><bad class='foo' data-foo='bar'> with some tags</bad><span>that I would</span><bad>like to replace</bad>"
new_text = replace_tags(text, "bad", "p")
print(new_text)  # "<p>this is some text<p><p class='foo' data-foo='bar'> with some tags</p><span>that I would</span><p>like to replace</p>"

我试过这个，但保留每个标签的属性是一个挑战：

def replace_tags(string, old_tag, new_tag):
  soup = BeautifulSoup(string, "html.parser")
  nodes = soup.findAll(old_tag)
  for node in nodes:
      new_content = BeautifulSoup("<{0}>{1}</{0}".format(
          new_tag, node.contents[0],
      ))  
      node.replaceWith(new_content)                                                
  string = soup.body.contents[0]
  return string

知道如何在汤中替换标签元素本身吗？或者，更好的是，有没有人知道一个库/实用程序函数能比我写的东西更强大地处理它？

谢谢！

实际上它非常简单。您可以直接使用typedef std::integral_constant<int, 2> two_t。

old_tag.name = new_tag

输出：

def replace_tags(string, old_tag, new_tag):
    soup = BeautifulSoup(string, "html.parser")
    for node in soup.findAll(old_tag):
        node.name = new_tag
    return soup  # or return str(soup) if you want a string.

text = "<p>this is some text<p><bad class='foo' data-foo='bar'> with some tags</bad><span>that I would</span><bad>like to replace</bad>"
new_text = replace_tags(text, "bad", "p")
print(new_text)

来自documentation：

每个代码都有一个名称，可以this is some text with some tagsthat I wouldlike to replace访问：
.name
如果您更改了标签的名称，则更改将反映在Beautiful Soup生成的任何HTML标记中：
tag.name
# u'b'

Python函数用另一个
