For this you need to alter the grammar.

There is one root grammar for your document, e.g. HTML for a HTML file.

This grammar will match tags like <style> and <script> and either  
include another grammar or put special rules only active inside this  
context.

If you want text between <pre>…</pre> to be marked up as Processing.js  
then you need to alter the HTML grammar to match <pre> tags and  
include a processing grammar for these (or define it inline).
