This was problematic, to say the least. To get around this, I figured that I could "cheat" by having a hidden element that would contain all of the ...

I have a regex, for example (ma|(t){1}). It matches ma and t and doesn't match bla. I want to negate the regex, thus it must match bla and not ma and t, by adding something to this regex. I know I can write bla, the actual regex is however more complex. ...

It only nearly worked. ^[ \t]* is wrong, since it matches one or non...
