plain-text file parsing

[Russell Klopfer]

Hello. I would like to know how I can parse a plain-text file. All I
want to do is be able to sequentially extract each word from a
document. Similar to the StringTokenizer in Java. Is there a module
for this? or an easy way to do it with regular expressions?

Thanks!

Dont really know what you want to do with the textfile.

A usual way to work with file:

open FILE, "/home/barry/text.txt" or
die "Cant open file";

while( $line = <FILE>)
{
... do something with $line ...
}

close FILE;


This parses the textfile line by line

Actually the idiomatic Perl way would be
while(<FILE>) {
... do something with $_ ...
}
