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?
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.
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.
You need to replace < by < and > by >. How to do this depends on the server side language in question.
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.
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.
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.
As other have noted, you need to escape the xml markup to display it in html.
Take a look at xmlverbatim stylesheet: It does that as well as pretty printing and colorizing.
If you google around there are several stylesheets to do similar formatting.
Do a substitution using a programming language without Emacs.
For Python:
#Make a copy just in case.
#Open file.
#Read lines.
for line in lines:
line = line.replace("<pre>", "<").replace("</pre>", ">")
#Output to file.
#Enjoy!
