检查 html 标签是否自关闭 - HTMLparser - Python [英] Check if html tag is self-closing - HTMLparser - Python

问题描述

有没有办法用 HTMLparser 来检查标签是否是自闭合标签?

Is there a way to check if a tag is a self-closing tag with HTMLparser?

我知道自闭标签是由内置函数处理的:handle_startendtag()

I know self-closing tags are handled by the built-in function: handle_startendtag()

然而，它只有在它们被明确关闭时才处理它们.例如 <img src="x.jpg"/>

However, it only handles them if they are explicitely closed..eg <img src="x.jpg"/>

而不是:<img src="x.jpg">

我正在制作一个程序，它接收一个 html 文件并输出一个 sass 模板.

I am making a program that takes an html file and spits out a sass template.

我想在输出文件中关闭这些在 html 文件中没有明确关闭的 img 标签.

I want to close these img tags in the output file that are not explicitly closed in the html file.

干杯

推荐答案

不完全是 Python 特定的解决方案，但是如果您想知道哪些 标签具有这种自关闭属性"，您可以可以查看官方的 HTML5 规范:这些规范的正式名称为 空元素.

Not exactly a Python-specific solution, but if you want to know which tags have this "self-closing property", you can look at the official HTML5 specs: these are formally known as void elements.

area, base, br, col, embed, hr, img, input, keygen, link, menuitem,
meta, param, source, track, wbr

严格来说，void 元素根本没有结束标签，但是 在 > 之前允许额外的 /.

Strictly speaking, void elements do not have closing tags at all, but permit an extra / immediately before the >.
