python - 使用 cElementTree 从 XML 查找所有节点

Question

有没有办法使用 cElementTree 查找 xml 树中的所有节点？ findall 方法仅适用于指定的标签。

Answer 1

您可以使用XPath paths关于 findall 方法:

The 1.2 release supports simple element location paths. In its simplest form, a location path is one or more tag names, separated by slashes (/).

You can also use an asterisk (*) instead of a tag name, to match all elements at that level. For example, */subtag returns all subtag grandchildren.

An empty tag (//) is used to search on all levels of the tree, beneath the current level. The empty tag must always be followed by a tag name or an asterisk.

etree.findall('.//*')
