Ti: Emerging minds.
Pu: Lakhotia
Pl: Varanasi

what I am trying to do is to get output in some new files in following
format

In file record1.txt

You will need (custom) file reader to get this file format into XML-
like document.

And then you can choose any XML processor/parser to do that.

you can read the file with CSVReader. Just tell is your field
separator is a ':' insteao of the usual ','.

I would not do this, just because it would be easy for a book title to
have ":" in it.

I'd have to see the actual file format spec, but it looks like the
identifier for the record type is always two letters at the beginning of
the line. I'd key off that. Just use readLine(), and check char(0) and
char(1). Dead simple, and bomb proof. Most likely faster too.

You can get the data from the file with regular expressions and
groupings. I haven't tried it, but this expression:
Record\ \#\ ([0-9])\ \n(Au: .+\n){1,}(Ti: .+\n)(Pu: .+\n)(Pl: .+)
would probably match well with what you want.
