How to write regex that match the answer block?

Question

I want to match the answer blocks (the bold ones).

A) I ve II B) III ve IV C) III ve IV D) III ve IV E) III ve IV

So far i wrote this.

(?:[A|B|C|D|E]\) )

It match this

A) I ve II B) III ve IV C) III ve IV D) III ve IV E) III ve IV

But when i append (.*) to it it matches

A) I ve II B) III ve IV C) III ve IV D) III ve IV E) III ve IV

How i can reverse match the regex that i wrote?

I need to reverse match the text because it can be everything on this block. A) example B) hello C) world D) goodbye E) something else

Thank you,

This should do the trick:

(?<=[A-E]\) ).*?(?= [A-E]\)|$)

I would consider using a lookahead based regex.

(?s)[A-E]\)\s*((?:(?!\s*[A-E]\)).)+)

But the string must have to be single line, otherwise it does not work. Is there any workaround for this? – Burak Tamtürk Jan 21 '15 at 09:09

you can also do

/I(II)? ve I(I|V)/

If your language supports inverse lookaheads:

?!(?:[A|B|C|D|E]\) )

So long as the answers always take that format, sure, but I'm guessing that they might not, and the idea is to key off the labels. – Scott Hunter Jan 20 '15 at 19:51
Thank you, but i forgot to mention it can be everyting on this block. A) example B) hello C) world D) goodbye E) something else – Burak Tamtürk Jan 20 '15 at 19:51
