请解释你的答案并提出论据.

此外，您认为其中一个会被弃用吗?哪一个?

Also, do you think one of them is going to get deprecated? Which one?

推荐答案

两者都不会被弃用.

ElementTree (xml.etree) 是一个用于访问 XML 的 Pythonic API.DOM (xml.dom) 是一种跨平台、独立于语言的标准.

ElementTree (xml.etree) is a pythonic API to access XML. DOM (xml.dom) is a cross-platform, language independent standard.

除非您有令人信服的理由改用 XML DOM，否则请使用 ElementTree.对于 python 代码，ElementTree API 比 DOM API 更容易使用.

Use ElementTree unless you have a compelling reason to use the XML DOM instead. For python code, the ElementTree API is far easier to use than the DOM API.

如果你不反对安装额外的 python 库，你应该看看 lxml 库 也是；它还在非常快速的 C 库之上实现了 ElementTree API，并添加了更多选项以有效处理 XML.

If you are not averse to installing extra python libraries, you should take a look at the lxml library as well; it implements the ElementTree API as well, on top of very fast C libraries, and adds a few more options to work with XML effectively.
