不需要的替代HTML实体由BeautifulSoup [英] Unwanted replacement of html entities by BeautifulSoup

问题描述

我有一些包含HTML MML，我使用MathType的Word文档生成。我有一个使用BeautifulSoup至prettify它一个python脚本，但问题是它需要像＆放大器;＃x2220; 键，把它变成实际的字节序列 0xE2均为0x88 0XA0 这是＆＃x2220;符号。这是一个问题，因为 0xE2均为0x88 0XA0 将没有显示＆＃x2220;在浏览器中。相反，浏览器间$ P $其中pts它作为一个系列的拉丁字符。这与所有的数学实体为好，如与三角洲发生的事情; ＆昂; ＆减去;与加; ...等

I have some html containing mml that I am generating from Word documents using MathType. I have a python script that uses BeautifulSoup to prettify it, but the problem is it takes something like ∠ and turns it into the actual byte sequence 0xE2 0x88 0xA0 which is the ∠ symbol. This is a problem because 0xE2 0x88 0xA0 won't display as ∠ in the browser. Instead the browser interprets it as a series of latin characters. This is happening with all the math entities as well, such as Δ ∠ − +... etc.

我从BeautifulSoup文件看，我可以看到如何把实体成字节序列，但我没有使用该命令;所有我使用的是prettify（）。而且我没有看到BeautifulSoup文档的方式不把实体为字节序列。

I looked through the BeautifulSoup documentation and I can see how to turn entities into the byte sequences, but I'm not using that command; all I'm using is prettify(). And I didn't see a way in the BeautifulSoup documentation to not turn entities into byte sequences.

有谁知道，如果有一个在BeautifulSoup的设置来告诉它不改变实体的字节序列？我希望如此，因为它似乎有点哑必须撤消prettify运行后的损害：）

Does anyone know if there's a setting in BeautifulSoup to tell it not to change entities to byte sequences? I hope so because it seems kind of dumb to have to undo the damage after prettify runs :)

在此先感谢您的帮助！

推荐答案

我错过了BeautifulSoup文件的一部分。默认的输出格式化做描述的行为：他们把HTML实体进入UNI code字符。所以，这种行为可以通过使用不同的输出格式而改变。 （D'哦）

I missed part of the BeautifulSoup documentation. The default output formatters do the described behaviour: they turn html entities into the unicode characters. So, this behaviour can be changed by using a different output formatter. (D'oh)

你可以通过提供格式化参数prettify（）的值更改此行为，EN code（），或者去code（）......

"You can change this behavior by providing a value for the formatter argument to prettify(), encode(), or decode()...."

所以，如果我通过了格式=HTML美丽的汤将统一code字符转换为HTML实体尽可能！好极了！谢谢美味的汤！

So if I pass in the formatter="html" Beautiful Soup will convert Unicode characters to HTML entities whenever possible! Yay! Thank you Beautiful Soup!

（他们有这么大的文档，可惜我没看过整个事情越早：。$）

(And they have such great documentation. Pity I didn't read the whole thing sooner. :$)
