Re^2: Putting an array into a hash

[Theo]

Thanks to the observations of Zaxo and you, I've gotten through some errors, misunderstandings and typos, but there is one error message I don't understand (even with use diagnostics). The whole program follows with the error listed first. The line giving the error is the one with the map command. It looks like the variables $1, $2 are somehow not being set. Perhaps the oddest aspect is that the program seems to work anyway. The error message is repeated 3 times.

Error:
Use of uninitialized value at e.pl line 13, <DATA> chunk 5.

Code:

#!/usr/bin/perl -w
my $file;
my @info;
my $line;
my %data = (one => 1, two => 2, three => 3);

foreach $file (<BXML=Tr*>) {
   open (DATA, $file);
    @info = <DATA>;        # @info contains the whole xml record
    foreach $line (@info) {
       chomp $line;
       $line =~ s|E-mail|Email|g;    # make email tags match all other
+ tags
       %data = map { /<(\w+)>\s*(.*?)<\/\w+>/; ($1, $2) } @info;
    }
    print "\n",$data{"Position"},"\t",$data{"GradYear"},"\t",$data{"Em
+ail"},"\n";
}
close (DATA);

OutPut:
Stdnt 1987 [e-mail]

So, can I safely ignore the error since the code does what I expect? Or is that asking for trouble?
