Extract Pattern Sequence

jaganadh · #1 (**permalink**) 12-10-2007

Dear Collegues
I have to extract Some pattern from raw text file using perl

The input will be raw text.
Pattern to get - Sequence of Capital Letter Words ( e.g. he is working in Center for Perl Studies. He will come tomorrow...) from thos I have to extract sequences like "Center for Perl Studies " and "C.P.S".

Any logic to impliment it in perl

Define sequence. You left "He" out of processing. Do you require 2,3,4...? items to be capitalized?

sequence : any sequence of Cpital letter e.g name of companies etc and abbriviations.

It is a very non-trivial problem,
for example:

Code:

billym.>X="he is working in Center for Perl Studies. He will come tomorr>
billym.>echo $X |perl -pe 's/([A-Z])\S*/$1\./g'                          
he is working in C. for P. S. H. will come tomorrow.

you could have a large list of ignore words maybe, like for, the, he, it, and

interesting, will I get paid?

Sequences like Center for Perl Studies

Code:

#!/usr/bin/perl
#
my @arraytest = ("Test", "for", "Capital", "letters");
my @resulttest = grep /[A-Z]/, @arraytest;
print "@resulttest\n"
