Converting string to array?

Hello,

I am trying to write a perl script to parse a string into an array. The
string has the fields separated by tabs. So what I want to do is read each
field into a variable so I can process the data further.

what I have is something like this;

open($rpt, $file);
while (<rpt>)
{
$line = $_;

#now what I want is something like
$field_1 = $line[0];
$field_2 = $line[1];
# of course this doesn't work so How do I do it?

}

An example string in the file might be like this.

995253 \t 1234 \t "address" \t "Name"


Thanks in advance for the help,
Sam

going to be missing out on much of Perl's usefulness. There are several
very good texts available, including "Mastering Regular Expressions" by
Jeffrey Friedl. And of course, Perl's own documentation is more than
adequate learning for a beginner.

A regex to process your data could be as simple as:

my ($field_1, $field_2) = $line_of_text =~ /^(\S+)\s+(\S+)/;

Which would stuff the first two fields into the declared variables. A
while() loop can also be useful to match an arbitrary number of fields,
and push them onto a stack.

And of course there's always CPAN.

BTW: this NG has been discontinued about a decade ago and replaced by the
the comp.lang.perl.* hirarchy. If you Usenet provider still carries it
instead of the 'new' hirarchy you may wonder what else he is missing.

If you know what to capture then use a RE, if you know what to throw away
then use split().

Thanks so much for the quick response from both you and Michael. I haven't
programmed for over 4 years so I'm having to re-teach myself so much. I was
only a moderately skill perl programmer to begin with. So much to learn
again. I'm one of those DOT com layoffs from that moved on to other things
in life. Selling Real Estate, so really doing nothing at all in computers.
However this report is something we do often and having worked in build
process and automation, I reconized that we could automate this report......
So guess who gets to do it! LOL


Thanks again,
Sam
