我刚刚开始使用简单XML
解析存储为$ scorexml的数据
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
[date-time] => 20140914T150400-0400
[language] => en-US
[document-class] => event-summary
[fixture-key] => leaderboard
[revision-id] => xt.21792812-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
)
)
)
)
)
)
)
并试图得到
echo $scorexml->sports-content->sports-metadata['doc-id'];
但是在尝试回显它时出现错误：
Parse error: syntax error, unexpected T_OBJECT_OPERATOR, expecting ',' or ';'
任何帮助表示赞赏。
因为元素是连字符的，所以您需要用{''}将它们包装起来。属性很好，因为它们像数组一样被访问，例如['doc-id']。如果元素包含连字符，则需要包装这些元素。
$scorexml->{'sports-content'}->{'sports-metadata'}['doc-id']
