访问xml字符串值

标签: xml perl

 my $profile_xml = $li->request(
 request_url         => 'http://api.linkedin.com/v1/people/~:(id,first-name,last-name,positions,industry,distance)',
 access_token        => $access_token->{token},
 access_token_secret => $access_token->{secret},
 );

 my $parser = XML::Parser->new( Style => 'Tree' );
 my $tree   = $parser->parse( $profile_xml );

我使用了上面的代码并得到了以下答案,但我不知道如何访问来自xml字符串

<person>
   <id></id>
   <first-name></firstname>
</person>

这些是字符串中的一些节点

  

$ VAR1 = ['person',[{},0,'','id',[{},0,'bEdA7NgdV8'],0,'   ','first-name',[{},0,'imm'],0,'','last-name',[{},0,'dee'   ],0,'','position',[{'total'=&gt; '1'},0,'','位置',[   {},0,'','id',[{},0,'3454532'],0,'','title',[{},0,   '软件工程师'],0,'','开始日期',[{},0,'','年',[   {},0,'2003'],0,'','月',[{},0,'6'],0,''],0,'',   'is-current',[{},0,'true'],0,'','company',[{},0,'',   'name',[{},0,'Ara Systems'],0,'','industry',[{},0,   '信息技术与服务'],0,''],0,''],0,''],   0,'','行业',[{},0,'信息技术和服务'],   0,'','距离',[{},0,'0'],0,'']];

Libxml会更容易和更健壮,但这里使用的是XML :: Parser。

use Data::Dumper;
$VAR1 = [ 'person', [ {}, 0, ' ', 'id', [ {}, 0, 'bEdA7NgdV8' ], 0, ' ', 'first-name', [ {}, 0, 'imm' ], 0, ' ', 'last-name', [ {}, 0, 'dee' ], 0, ' ', 'positions', [ { 'total' => '1' }, 0, ' ', 'position', [ {}, 0, ' ', 'id', [ {}, 0, '3454532' ], 0, ' ', 'title', [ {}, 0, 'Software Engineer' ], 0, ' ', 'start-date', [ {}, 0, ' ', 'year', [ {}, 0, '2003' ], 0, ' ', 'month', [ {}, 0, '6' ], 0, ' ' ], 0, ' ', 'is-current', [ {}, 0, 'true' ], 0, ' ', 'company', [ {}, 0, ' ', 'name', [ {}, 0, 'Ara Systems' ], 0, ' ', 'industry', [ {}, 0, 'Information Technology and Services' ], 0, ' ' ], 0, ' ' ], 0, ' ' ], 0, ' ', 'industry', [ {}, 0, 'Information Technology and Services' ], 0, ' ', 'distance', [ {}, 0, '0' ], 0, ' ' ] ];

print Dumper($VAR1->[1]->[3],$VAR1->[1]->[4]->[2]);

print Dumper($VAR1->[1]->[7],$VAR1->[1]->[8]->[2]);

$VAR1 = 'id';
$VAR2 = 'bEdA7NgdV8';
$VAR1 = 'first-name';
$VAR2 = 'imm';
