确定元素的直接子元素是否为某些标记

Question

有没有办法在BeautifulSoup？

中写这个

for node in soup:
  if node is in ["a", "b", "i", ...]: # node is tag of type `a` or `b` ...
    # we are probably on the text level
    textLevelFlag = true
  else:
    # "we are higher"

Answer 1

如果您想测试您的代码是否只有文字元素，可以试试这个：

if hasattr(node, contents) and len(node.contents) == 1 and isinstance(node.contents[0], NavigableString):
    textLevelFlag = true
else:
    something else
