xml - 通过 GetGetElementByTheTagName 从响应 xml 中检索值

Question

  Getting the  linkedin user profile

     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},

);

我得到了结果，但我想分别获取 id、名字、姓氏。如何使用 GetElementByTheTagName 来检索值。

Answer 1

如果您能够像这样管理 xml 内容：

 $str = '<id>bYdSs9C</id><first-name>Jack</first-name> <last-name>Rudloph</last-name>';

我们可以使用它来获取字段

while ($str =~ /<.*?>(.*?)<\/.*?>/g) {
        print $1, "\n";
}

Answer 2

Here i am showing that how to parse the linked profile values from xml which is received in the response but not by the GetElementbyTheTagname.

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

  my $UID = $tree->[1]->[4]->[2],"\n";
  print "User ID:$UID";
  print"</br>";

This is the way we can parse the values from the received response.
