in reply to Removing digits until you see | in a string

A couple of suggestions. The following uses a substituation and removes the index from the rest of the data (i.e. the original data is changed).

$data_hash{$1}= $str if $str =~ s/(\d+)\|//;
This uses matches the index and remaing data without altering the original.
$data_hash{$1}= $2 if $str =~ /(\d+)\|(.*)$/;
I have used a conditional to assess the validity of the assignment beforehand. This is useful for data processing where the quality of the data is variable.
