Hi there,
I have the following problem:
I want to read a logfile in which every line follows this rule:
<value1>:<value2>:<value3>...
But the number of values differs. Sometimes a line has 2 values (the
minimum) and sometimes 3 or more values. Now I want to push these
values into a hash that follows that form:
$hash->{value1}->{value2}...
This is what I have so far:
sub readLog {
my $self = shift;
my $logfile = getFilename();
open LOG, "<$logfile";
foreach my $line (<LOG>) {
my @values = split /\:/, $line;
... # at this point I don't know what to do :(
}
}
Greetings

I know a weird question that you likely already thought about but still why
are you not using a combination of array and hash?
$hash->{value1} = [ value2, value3, value4, ... ]
It would save you a lot of headaches in looping over all values that are on
that one line because how are you going to easily handle a situation where
you have a hash of hashes with an undefined depth without having to jump to
a lot of difficult hoops to make it work properly?
