Syntax highlighting woes

I am having some trouble with the setup of my posts.
I want the perl scripts that I publish to use the same syntax highlighting that you get in Notepad++.
So I used the NppExport plugin of Notepad++ and exported to a .html document (tried to a .rtf file also).
I copied and pasted the html code from the created html file to the WYSIWYG editor of blogger but the text formating has disappeared and I end up with something like that:

#!/usr/bin/perl

use warnings;

print "This is not so easy";

Then I tried to copy the html code from the exported html file into the "Edit Html" tab of the editing window but it doesnt work any better.

I have googled syntaxhighlighter but it doesn't support the Perl syntax. Somebody was nice enough to create a Perl extension. So I'll be trying it out in the next few hours. I will try re-publishing yesterday's post so don't go thinking that your feed reader has gone crazy.
And sorry for the inconvenience, I'm learning here ;)
