How to parse a text starting with a flag till another special flag?

How can I parse this in Perl?

AA: something in here
and it continues in the next 
and the third
and the n number of lines till the next flag
BB: some new text is here
CC: some other text is also here

Open in new window

This text can also be in this format:

BB: some new text is here
AA: something in here
and it continues in the next 
and the third
and the n number of lines till the next flag
CC: some other text is also here

Open in new window

AA: BB: CC: are the flags.

The expected output is:

something in here
and it continues in the next 
and the third
and the n number of lines till the next flag

Open in new window

The idea for this can be:

Parse everything that starts with AA: till (BB: or CC:)

How can I do that in Perl?

If this is my original code: (The more complex form of this question is in ID: 27388059)

/^C(S|omments):\s*(.*\n)/ && push(@CS, $2) && goto CHECK;

Open in new window

Can I change it like this with your code in stead of new line character:

/^C(S|omments):\s*(\s*// .. s/\s*(RR|CR|Mail sent to):.*)/ && push(@CS, $2) && goto CHECK;

Open in new window

The thing that I wanna parse is in these formats:

CS:  some text in here
and continues in here
RR:something in here
CR: something in here

Mail sent to: some other thing

Open in new window

RR:something in here
CS:  some text in here
and continues in here
CR: something in here


Mail sent to: some other thing

Open in new window

RR:something in here
CR: something in here
CS:  some text in here
and continues in here

Mail sent to: some other thing

Open in new window

The part that I wanna capture is:

sometext in here
and continues in here

Open in new window

Do you think it is ok?

Thanks,

Suhas .
