Rosetta Code:Village Pump/Pre to Lang Tag Fixer

I'm thinking, if we did Code Tag Fixer, why not make a Pre Tag Fixer? I already did a bot, but i need a hash/dict, like this:

Python= python

C Sharp = csharp

Java = java5

Common Lisp = lisp

I need this, because just lowercasing and removing spaces isn't very secure.

Input: <lang>

<lang python>
aiaiai
</lang>

=={{header|C sharp}}==
<lang csharp>
