如何在Emacs中使用HTML显示XML源代码?

In the HTML file, I need to show some XML code. The problem is that I can't use

在HTML文件中，我需要显示一些XML代码。问题是我不能用

<pre>..</pre>

to show '<' and '>'.

显示'<'和'>'。

What would be the solution for this problem?

这个问题的解决方案是什么?

ADDED

From the answer, replacing '<' and '>' to < and> can be a solution. I'm an Emacs user, are there Emacs tools/magic to do that automatically? I mean, I can use search and replace, but I expect Emacs can do it by 'select region' -> 'M-x replace_xml' or something.

从答案开始，将'<'和'>'替换为<and>可能是一个解决方案。我是一个Emacs用户，有Emacs工具/魔法可以自动完成吗?我的意思是，我可以使用search和replace，但我希望Emacs可以通过'select region' -> 'M-x replace_xml'或其他方法实现这一点。

You need to escape < as < and & as &. Optionally, for consistency, you can escape > as >

你需要逃离< as <和和,。可选地，为了一致性，您可以将>转义为>

To do this automatically in Emacs, if you're in HTML mode, you can select the code that you would like to escape, and run M-x sgml-quote.

要在Emacs中自动执行此操作，如果您处于HTML模式，您可以选择要转义的代码，并运行M-x sgml-quote。

You need to replace < by < and > by >. How to do this depends on the server side language in question.

你需要替换< by <并通过祝辞>。如何做到这一点取决于问题中的服务器端语言。

Update: as per your update: this is not programming related anymore. I think http://superuser.com is a better place to ask software related questions.

更新:根据您的更新:这不再与编程相关。我认为http://superuser.com是一个询问软件相关问题的好地方。

As already mentioned, you need to escape the XML. For robustness I would also escape single and double quotes too. Note that CDATA and <pre> can cause you problems if, for any reason, your XML document includes ]]> or </pre> in it.

如前所述，您需要避开XML。对于健壮性，我还将避免使用单引号和双引号。注意，如果您的XML文档中包含[]>或，那么CDATA和

会导致问题。

You can get away with doing a straight string substitution for the escaping, but if you do, make sure you escape & to & before doing any of the other escapes.

你可以做一个直接的字符串替换来代替转义，但是如果你做了，确保你转义了& to &在做任何其他逃跑之前。

#4

As other have noted, you need to escape the xml markup to display it in html.

如前所述，您需要转义xml标记以在html中显示它。

Take a look at xmlverbatim stylesheet: It does that as well as pretty printing and colorizing.

看一下xml逐字样式表:它可以很好地进行打印和着色。

If you google around there are several stylesheets to do similar formatting.

如果您在谷歌附近有几个样式表来执行类似的格式化。

Select the region
选择该地区
Do M-% < RET < RET !
执行M-% < RET <受潮湿腐烂!

#6

Do a substitution using a programming language without Emacs.

使用没有Emacs的编程语言进行替换。

For Python:

Python:

#Make a copy just in case.
#Open file.
#Read lines.
for line in lines:
    line = line.replace("<pre>", "&lt;").replace("</pre>", "&gt;")
#Output to file.
#Enjoy!
