I will try this, but in my attempt to understand the code,
what part is 
a "negative look ahead/look behind" ?

Short answer:
(?!--->) = negative look-ahead
(?<!<!--) = negative look-behind


And in an attempt to educate, hopefully without causing
confusion:

1: Negative look-ahead is .*(?!wobble)
2: Positive look-ahead is .*(?=wobble)
3: Positive look-behind is (?<=wibble).*
4: Negative look-behind is (?<!wibble).*

So if you have the text "wibblewobble", 2 and 3
will match it, but 2 will
return only the "wibble", whilst 3 only returns
"wobble".
If you have text "wibblesplat", 1 will match it
and return "wibble", but
2/3/4 wont.
If you have text "splatwobble", 4 will match it
and return "wobble", but
1/2/3 wont.

(I *think* that's right)
