Org-mode: protect emphasis - emacs

Question

How could I protect emphasis like italics or code within Emacs org-mode
when I have things like
/cologne/dome/
or
=<pre language="python">=
?

Answer 1

The following org-block demonstrates which parts work by default and which need a small amount of work-around to work.
The following was created using Org-mode version 7.8.03 (release_7.8.03.321.gaac1c). If you're using an older version it is possible that the behaviour is slightly different.
See Literal Examples and Monospace in the Org-Manual for full details
ORG
* Italics
- Your example simply works\\
/cologne/dome/
- It also works if your /example had / spaces within it/
- It will only fail if / your /have spaces on one end or the other /
* Code
Code blocks can be delimited in multiple ways:
** Inline formatting
- Using ~ for verbatim text works\\
~<pre language="python">~
- ~ renders the same as = for blocks =test= ~test~
** Code Blocks
- Single-line blocks
: <pre language="python">
- Multi-line blocks

Answer 2

I guess you want to output the original /cologne/dome/, but not <i>cologne/dome</i>, right?
Two ways:
set #+OPTIONS: *:nil to turn off all emphasis symbols
modify org-emphasis-alist, remove the relevant items
I also asked a similar question here: How do I escape slash in org-mode?
