And what is your “problem with Ruby”? You sure do not expect us to do
your homework for you, do you?

We certainly can help you with debugging your code, but writing a
script from scratch is a bit much to ask. :slight_smile:

If you need a starting point, investigate the File, Array, Hash and
String classes.

Note: It’s a bad idea to post personal information (like a student’s
name and ID number) on the internet.

(Ah, how soon!) they forget
When I’ve moved on to some other place,
There may be one or two,
When I’ve played and passed through,
Who’ll remember my song or my face.

i need code by ruby regular expression and i am new to this language so
i need to solve this problem to know what happen exactly.
note: the information is not real.

You still haven’t asked a question, you just told us that you need to
write a script. Go ahead and write one. If you run into questions
doing so, ask them.

Break the problem down. What is given? First a file. So you need to
“read”
the “File”. Look up File.read and read about that.

Okay if you have done that, let’s say you have read the file into a
variable called text.

Now you need to extract information from that text. How will you do
this?
There a basically two ways: by position or by pattern. So you need to
figure out what about the file is always the same no matter which
students
record it is and use that as a guide to locate the other information.

For example the number appears like so:

*Number :*     20085252

You could get this information by matching against the Number : part
so
as to find the rest. So something like

  match = /\*Number\s*:\*(\d+)/.match(text)

The characters in between the /…/ are a Regular Expression. Look that
up
and read about them. Notice we had to use \ in some places to “escape”
characters or to indicate a special type of character, e.g. \d means any
digit.

Because of the (\d+) we have capture the digits in the first match
element,
so:

  number = match[1]

Now you should be able to read up on the things I suggested and work out
how to do it for the rest of the information.

And have fun. It’s a like a puzzle, not a chore.
