訪問的SimpleXML屬性

解析存儲爲$ scorexml

SimpleXMLElement Object 
(
[@attributes] => Array 
    (
     [query-date-time] => 20141009T175358-0400 
     [query-string] => hidden 
     [hostname] => hidden.com 
     [result-count] => 1 
     [error-count] => 0 
     [total-count] => 9 
     [elapsed-time] => 13.0ms 
    ) 

[sports-content] => SimpleXMLElement Object 
    (
     [sports-metadata] => SimpleXMLElement Object 
      (
       [@attributes] => Array 
        (
         [doc-id] => xt.21794675-Golf_Leaderboard_XML

        ) 

       [sports-title] => $8,000,000 The Tour Championship Leaderboard 
       [sports-content-codes] => SimpleXMLElement Object 
        (
         [sports-content-code] => Array 
          (
           [0] => SimpleXMLElement Object 
            (
             [@attributes] => Array 
              (
               [code-type] => publisher 
               [code-key] => sportsnetwork.com 
              ) 

            ) 

           [1] => SimpleXMLElement Object 
            (
             [@attributes] => Array 
              (
               [code-type] => priority 
               [code-key] => normal 
              ) 

            ) 

           [2] => SimpleXMLElement Object 
            (
             [@attributes] => Array 
              (
               [code-type] => sport 
               [code-key] => 15027000 
              ) 

            ) 

           [3] => SimpleXMLElement Object 
            (
             [@attributes] => Array 
              (
               [code-type] => league 
               [code-key] => l.pga.com 
              ) 

            ) 

          ) 

        ) 

      ) 

    ) 

)

這些數據，並試圖讓

echo $scorexml->sports-content->sports-metadata['doc-id'];

但得到一個錯誤，當我嘗試以迴應它：

Parse error: syntax error, unexpected T_OBJECT_OPERATOR, expecting ',' or ';'

任何幫助表示讚賞。

你能後的XML也是如此。 – slapyo 2014-10-09 22:12:51

請實際閱讀[PHP手冊]中的[「Basic SimpleXML用法」一節]（http://php.net/manual/en/simplexml.examples-basic.php）。大部分SimpleXML問題已經得到解答，請在提問前使用搜索。 – hakre 2014-10-10 13:45:00

因爲元素是連字符的，所以你需要用{''}來包裝它們。屬性很好，因爲它們像數組一樣被訪問，就像['doc-id']一樣。如果它們包含連字符，則需要包裝這些元素。

$scorexml->{'sports-content'}->{'sports-metadata'}['doc-id']
