How to display XML source code using HTML with Emacs?

Question

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

<pre>..</pre> 

to show '<' and '>'.

What would be the solution for this problem?

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.

Answer 1

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

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.

Answer 2

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