I am currently writing a small texteditor. With this texteditor users are able to create small scripts for a very simple scripting engine.

For a better overview I want to highlight codeblocks with the same command like GoTo(x,y) or Draw(x,y).

To achieve this I want to use Regular Expresions (I am already using it to highlight other things like variables)

Here is my Expression (I know it's very ugly):

/(?<!GoTo|Draw|Example)(^(?:GoTo|Draw|Example)\(.+\)*?$)+(?!GoTo|Draw|Example)/gm

It matches the following:

lala 
GoTo(5656)               -> MATCH 1
sdsd
GoTo(sdsd) --comment     -> MATCH 2
GoTo(23329);             -> MATCH 3
Test() 
GoTo(12)                 -> MATCH 4
LALA
Draw(23)                 -> MATCH 5
Draw(24)                 -> MATCH 6
Draw(25)                 -> MATCH 7

But what I want to achieve is, that the complete "blocks" of the same command are matched. In this case Match 2 & 4 and Match 5 & 6 & 7 should be one match. Tested with http://regex101.com/, the programming lanuage is vb.net. Any advise would be very useful, Thanks in advance!
