使用Python的ElementTree查找顶级xml注释 [英] Finding top-level xml comments using Python's ElementTree

问题描述

我正在使用Python的ElementTree解析xml文件，例如：

I'm parsing an xml file using Python's ElementTree, like that:

et = ElementTree(file=file("test.xml"))

test.xml以几行xml注释开头。

test.xml starts with a few lines of xml comments.

有没有办法从et中获得这些评论？

Is there a way to get those comments from et?

推荐答案

对于ElementTree 1.2.X，有一篇文章使用ElementTree
阅读处理说明和注释（ http://effbot.org/zone/element-pi.htm）。

For ElementTree 1.2.X there is an article on Reading processing instructions and comments with ElementTree (http://effbot.org/zone/element-pi.htm).

编辑：

替代方法是使用实​​现ElementTree API的 lxml.etree 。 lxml.etree
的元素树兼容性的引用：

The alternative would be using lxml.etree which implements the ElementTree API. A quote from ElementTree compatibility of lxml.etree :

ElementTree在解析
XML时会忽略注释和
处理指令，而 etree会在其中读取它们和
分别将它们视为Comment或
ProcessingInstruction元素
。

ElementTree ignores comments and processing instructions when parsing XML, while etree will read them in and treat them as Comment or ProcessingInstruction elements respectively.
