if($q[1]=~/^B-/)
{
$p=$';
$m=$q[0] if( $q[1] =~/^B-/ or $q[1]="o");
$out.="<annotation>\n<key=type>$p</type>\n<text>$m</text>\n</annotatio
+n>\n";
}
}
print"$out\n";

At your own risk, splitting on tab:

use strict;
use warnings;

open my $words, "<", "words.txt" or die "Cannot open words.txt: $!\n";

my $lasttype;
my @text;
while( <$words> ) {
        chomp;
        my @row = split /\t/;
        my $text = $row[0];
        my $type = ( $row[-1] =~ /\w-(\w+)/ ) ? $1 : "";
        $lasttype = $type unless @text; # special treatment for first 
+row
        if( $type eq $lasttype ) {
                push @text, $text;
        } else {
                print '<key="type">'."$lasttype</key><text>@text</text
+>\n" if $lasttype;
                $lasttype = $type;
                @text = ( $text );
        }
}

# print what's left over when all input read
print '<key="type">'."$lasttype</key><text>@text</text>\n" if $lasttyp
+e;

close $words;

It is working but this error is popping up Use of uninitialized value in pattern match (m//) at f.pl line 14, <$words> line 18.

Is line 18 empty in your file? You would need to add code to skip empty lines.
