推荐答案
默认情况下，当您访问<$ c $在Emacs（22或23）中的c> .html 文件，它将使您进入 html-mode 。这可能不是你想要的你可能想要 nxml-mode ，这是非常好看的。 nxml-mode 似乎只有Emacs 23，虽然你可以从。还有一个名为 nxml-mode 的Debian和Ubuntu软件包。您可以输入 nxml-mode ：
By default, when you visit a .html file in Emacs (22 or 23), it will put you in html-mode. That is probably not what you want. You probably want nxml-mode, which is seriously fancy. nxml-mode seems to only come with Emacs 23, although you can download it for earlier versions of emacs from the nXML web site. There is also a Debian and Ubuntu package named nxml-mode. You can enter nxml-mode with:
M-x nxml-mode
您可以查看nxml模式文档：
You can view nxml mode documentation with:
C-h i g (nxml-mode) RET
说，您可能必须使用等重新格式化您的xhtml示例。 nxml-mode 将从
All that being said, you will probably have to use something like Tidy to re-format your xhtml example. nxml-mode will get you from

</html>
但是，我没有看到更通用的功能，可以在某些xml标签上进行换行符。请注意， Cj 将插入一个具有适当缩进的新行，因此您可能可以执行一个快速宏或黑客攻击 defun 将会做你的表。
but I don't see a more general facility to do line breaks on certain xml tags as you want. Note that C-j will insert a new line with proper indentation, so you may be able to do a quick macro or hack up a defun that will do your tables.
