脚本：

[root@dou xml]# cat w1.pl
#!/usr/bin/perl -w
use strict;
use XML::Writer;
use IO::File;

my %host = (
??????? 'name' => 'perl',
??????? 'addr' => '192.168.0.6',
);

my $FH = IO::File->new(">output.xml");
my $writer = XML::Writer->new(OUTPUT => $FH);
$writer->xmlDecl("UTF-8");
$writer->startTag("network");
print $FH "n";
$writer->startTag('host');
foreach my $field (keys %host) {
??????? print $FH "n ";
??????? $writer->startTag($field);
??????? $writer->characters($host{$field});
??????? $writer->endTag;
}
print $FH "n";
$writer->endTag;
print $FH "n";

$writer->endTag;
$writer->end;
$FH->close();
[root@dou xml]# perl w1.pl

执行结果： [root@dou xml]# cat output.xml <?xml version="1.0" encoding="UTF-8"?> <network> <host> ?<name>perl</name> ?<addr>192.168.0.6</addr> </host> </network> [root@dou xml]# ?
