XML ::在输出

Question

我试图使用XML序列化下面的数据结构使用自卸车错误的散列引用::自卸车

'options_settings' => { 
    'telnet.distinct.enable' => { 
    'text' => 'Option telnet.distinct.enable needs to be set to \'on\' as of 
workaround for Bug 476803', 
    'severity' => '7' 
    } 
}, 
'EOS_details' => { 
    '338' => bless({ 
    'info' => '<a href="https://support.netapp.com/info/communications/ECMP1110462.html " target="_blank"> CPC-0705-02 </a>', 
    'count' => '48', 
    'ASUP_id' => 'AE20121117202086', 
    'part' => 'ESH2 - X5511A-RC, X5511-RC-C', 
    'category' => 'I/O Module', 
    'EOS_date' => '06/02/2013', 
    'severity' => '8' 
    }, 'EOSObject'), 

的问题是，当我分析它为XML和XML：自卸车它使用2个独立散列引用的相同内存地址：

<item key="338"> 
    <hashref blessed_package="EOSObject" memory_address="0x295b5758"> 
    <item key="ASUP_id">AE20121117165273</item> 
    <item key="EOS_date">06/02/2013</item> 
    <item key="category">I/O Module</item> 
    <item key="count">48</item> 
    <item key="info">&lt;a href=&quot;https://support.netapp.com/info/communications/ECMP1110462.html &quot; target=&quot;_blank&quot;&gt; CPC-0705-02 &lt;/a&gt;</item> 
    <item key="part">ESH2 - X5511A-RC, X5511-RC-C</item> 
    <item key="severity">8</item> 
    </hashref> 
    </item> 
</hashref> 
<item key="options_settings"> 
<hashref memory_address="0x295b5320"> 
    <item key="telnet.distinct.enable"> 
    <hashref memory_address="0x295b5758"> 
    </hashref> 
    </item> 
</hashref> 
</item> 

请注意memory_address =“0x295b5758”。

所以从读回文件时option_settings散列引用指向EOS对象：/

的是，在XML中的错误::自卸车还是我做错了什么？使用最新的XML :: Dumper 0.81

P.S. 我试图在主脚本之外重现它，它工作。 我仍然无法理解主要脚本中的数据如何被破坏。 这是其中使用XML ::自卸车的代码：

DEBUG("Before serialization: " . Data::Dumper::Dumper($result)); 
    my $dump = new XML::Dumper; 
    my $dump_test = new XML::Dumper; 
    my $test_xml = $dump_test->pl2xml ($result); 
    DEBUG("After serialization in memory: " . Data::Dumper::Dumper($test_xml)); 
    $dump->pl2xml($result, $filename); 

结果被适当地打印出来。 “options_settings”是单独的条目。在$ test_xml中它已经与EOS_details混淆了

我试图在没有任何成功的情况下复制您的问题。

#!/usr/bin/perl -Tw 

use strict; 
use warnings; 
use XML::Dumper; 

my $eos = bless { 
    'info'  => '<a href="https://support.netapp.com/info/communications/ECMP1110462.html " target="_blank"> CPC-0705-02 </a>', 
    'count' => '48', 
    'ASUP_id' => 'AE20121117202086', 
    'part'  => 'ESH2 - X5511A-RC, X5511-RC-C', 
    'category' => 'I/O Module', 
    'EOS_date' => '06/02/2013', 
    'severity' => '8' 
    }, 'EOSObject'; 

my %data = (
    'options_settings' => { 
     'telnet.distinct.enable' => { 
      'text'  => 'Option telnet.distinct.enable needs to be set to \'on\' as of 
workaround for Bug 476803', 
      'severity' => '7' 
     } 
    }, 
    'EOS_details' => { 338 => $eos } 
); 

print pl2xml(\%data); 

我的程序的输出：

    <item key="EOS_details">

    <hashref memory_address="0x2517598"> 
     <item key="severity">7</item> 
     <item key="text">Option telnet.distinct.enable needs to be set to &apos;on&apos; as of

我倾向于认为有什么东西掉你的程序。 :(
