Adding _after_ the more general rule e.g. for CDATA, when you match  
CDATA, is not going to work. It is the first rule in the grammar which  
matches a construct, which wins.

The patterns are single-line matches. Your script + CDATA is split  
over two lines, so you will have to change strategy to match this,  
i.e. write an outer rule to match <script> with an inner rule to match  
CDATA (if necessary).
