I'm sending this on behalf of our intern Elmer. Thanks in advance for any assistance. Chris
Hi there!
If anyone out there is good with Perl's pattern matching, maybe you can help me out. I am trying to take a string and derive information from it that is separated by commas so I can then analyze the individual values.
So if I have a string like: 'Associated Press, John. D. Reporter, 01 Apr 2005'
I want to be able to scan it, and extract 'Associated Press' 'John. D. Reporter' and '01 Apr 2005' as distinct values--maybe store them as variables so I can manipulate them.
It should also be that the number of data items not be relevant. In case the string is like 'Joe Freelancer, 01 May 2005' or 'Reuters, 01 Jun 2005'. Or if it has no commas and is just '01 Jul 2005'.
Kind regards,
Elmer Zahraie
Check out the 'split' function.
perldoc -f split
my @items = split /,/, $string;
Is the simplest, but you may need to take into account whitespace, etc. Also note that if you are parsing data that is coming in a true CSV format, aka with quoted values that might contain commas, etc. then you should consider using a module designed for this purpose, such as something in the Text::CSV range.
