I want to convert an xml file to csv. I found some code online and modified to my purpose, but I dont know enough about perl to further fix it. 
    

use strict; 
use XML::Rules; 
use Text::CSV_XS; 
use FileHandle; 
 
my $csv = Text::CSV_XS->new({eol => "\n"}); 
my $parser = XML::Rules->new( 
        rules => [ 
                _default => 'content', 
                Class => sub { 
                        $csv->print( $_[4]->{parameters}, [ 
                                map {$_[1]->{$_}} qw( 
                                        Subject Course Title Descripti
+on Prequisites Corequisites Requisites LectureHours LaboratoryHours C
+reditHours Flags 
                                ) 
                        ]); 
                        return; 
                } 
        ] 
); 
 
open my $FH, '>&STDOUT'; 
open my $File, 'alpha31.xml'; 
print $FH "Subject,Course,Title,Description,Prequisites,Corequisites,L
+ectureHours,LaboratoryHours,CreditHours,Flags\n"; 
 
$parser->parse( $File, $FH);

It converts it to xml the way I want to, but it only does a single line and then complains about garbage after the </class> tag. Could anyone help me have this work on the entire file. I have posted 4 entries from the xml file which should print out 4 csv rows.
