答案 0 :(得分：1)
如果我正确理解，则想删除所有<condition>标签。您可以使用.extract() [bs4-doc]：
for cond in soup.find_all('condition'):
cond.extract()在此循环之后，<condition>的所有soup标签将消失，print(..) soup的{{1}}将导致没有这些标签的流。
话虽这么说，通常可以使用XSLT完成简单的XML处理，XSLT是XML中的XML转换标准...）。
例如：
>>> soup

因此，在这里我们看到cond.extract()返回XML元素（（这些元素打印在for循环中，但是我们对此不做任何操作，在Python程序中，值当然是未打印）。在for循环之后，所有<condition>标签都将被删除。
