$ cat -n simple1.pl 显示XML的代码

1    #!/usr/bin/perl
2    # simple.pl
3    use Data::Dumper;
4    use warnings;
5    use strict;
6    use XML::Simple;
7    my ($simple,$data,$date);
8    $simple=new XML::Simple(forcearray=>1);
9    $data=$simple->XMLin('./invoice.xml');
10   
11    print Dumper $data;

其中invoice.xml为

<?xml version="1.0" standalone="no"?>
<!DOCTYPE invoice SYSTEM "inXML.dtd">
