ive read a load of data in from a CSV file with Text::CSV and ended
up with a hash (%hash) where the keys are the column labels.
my @headings=split(/,/,$rows[0])
and then
for (my $j=1;$j<$#rows;$j++)
{
my $status = $csv->parse ($rows[$j]); # parse a CSV string into
fields
my @columns = $csv->fields (); # get the parsed fields
for (my $i=0;$i<$#columns;$i++)
{$hash{$headings[$i]}=$columns[$i];}
I want to process the data once its grouped by the date field present
in $hash. So i think I want a hash of dates where the key is that
date field
I push onto the value the hashes of the records that contain the date
push @{$Hofdates{$hash{DATE}}},\%hash;
but im having a problem working out how to access the individual
items in the hashes that are elements of the array
