由于特殊字符@和破折号而无法使用PHP显示Simple XML Elements？

请注意“ @”属性和破折号，例如“ MAP-SETS” SimpleXML输出转储示例：

 object(SimpleXMLElement)#1 (5) { ["@attributes"]=> array(8) { ["date"]=> string(10) "2013-07-30" ["equipment"]=> string(16) "RANGER 2" ["id"]=> string(5) "B0.17" ["name"]=> string(14) "abcdefg" ["sn"]=> string(9) "012345" ["time"]=> string(8) "06:24:24" ["trademark"]=> string(24) "ELECTRON, INC" ["version"]=> string(3) "1.0" } ["MAP-SETS"]=> object(SimpleXMLElement)#2 (1) { ["MAP-SET"]=> array(9) { [0]=> object(SimpleXMLElement)#6 (1) { ["@attributes"]=> array(5) { ["band"]=> string(11) "TERRESTRIAL" ["date"]=> string(10) "2017-10-05" ["equipment"]=> string(6) "RANGER" ["name"]=> string(13) "AMP-ANT1" ["version"]=> string(3) "1.1" } } [1]=> object(SimpleXMLElement)#7 (1) { ["@attributes"]=> array(5) { ["band"]=> string(11) "TERRESTRIAL" ["date"]=> string(10) "2017-10-05" ["equipment"]=> string(6) "RANGER" ["name"]=> string(13) "AMP-ANT2" ["version"]=> string(3) "1.1" } } [2]=> object(SimpleXMLElement)#8 (1) { ["@attributes"]=> array(5) { ["band"]=> string(11) "TERRESTRIAL" ["date"]=> string(10) "2017-07-25" ["equipment"]=> string(6) "RANGER" ["name"]=> string(13) "AMP-ANT3" ["version"]=> string(3) "1.1" } } [3]=> object(SimpleXMLElement)#9 (1) { ["@attributes"]=> array(5) { ["band"]=> string(11) "TERRESTRIAL" ["date"]=> string(10) "2018-09-10" ["equipment"]=> string(6) "RANGER" ["name"]=> string(13) "AMP-ANT4" ["version"]=> string(3) "1.1" } } [4]=> object(SimpleXMLElement)#10 (1) { ["@attributes"]=> array(5) { ["band"]=> string(11) "TERRESTRIAL" ["date"]=> string(10) "2017-10-05" ["equipment"]=> string(6) "RANGER" ["name"]=> string(13) "AMP-ANT5" ["version"]=> string(3) "1.1" } } [5]=> object(SimpleXMLElement)#11 (1) { ["@attributes"]=> array(5) { ["band"]=> string(11) "TERRESTRIAL" ["date"]=> string(10) "2017-07-25" ["equipment"]=> string(6) "RANGER" ["name"]=> string(13) "AMP-ANT8" ["version"]=> string(3) "1.1" } } [6]=> object(SimpleXMLElement)#12 (1) { ["@attributes"]=> array(5) { ["band"]=> string(11) "TERRESTRIAL" ["date"]=> string(10) "2017-07-25" ["equipment"]=> string(6) "RANGER" ["name"]=> string(13) "AMP-ANT9" ["version"]=> string(3) "1.1" } } [7]=> object(SimpleXMLElement)#13 (1) { ["@attributes"]=> array(5) { ["band"]=> string(11) "TERRESTRIAL" ["date"]=> string(10) "2018-09-10" ["equipment"]=> string(6) "RANGER" ["name"]=> string(13) "AMP-ANT6" ["version"]=> string(3) "1.1" } } [8]=> object(SimpleXMLElement)#14 (1) { ["@attributes"]=> array(5) { ["band"]=> string(11) "TERRESTRIAL" ["date"]=> string(10) "2018-09-10" ["equipment"]=> string(6) "RANGER" ["name"]=> string(13) "AMP-ANT7" ["version"]=> string(3) "1.1" } } } } ["ATTENUATION-TESTS"]=> object(SimpleXMLElement)#3 (0) { } ["OPTIONS"]=> object(SimpleXMLElement)#4 (3) { ["CAPTURE-PSI"]=> object(SimpleXMLElement)#14 (1) { ["@attributes"]=> array(1) { ["value"]=> string(5) "false" } } ["PAUSE-CHSETS"]=> object(SimpleXMLElement)#13 (1) { ["@attributes"]=> array(1) { ["value"]=> string(4) "true" } } ["FSM"]=> object(SimpleXMLElement)#12 (1)

这有效： $ xml = simplexml_load_file（“ test.XML”）; var_dump（$ xml）;

但是当我尝试调用单个项目时，根据我的操作，会出现不同的错误。例如：意外的[[，期望的标识符（T_STRING）或变量（T_VARIABLE） 此示例不起作用：

echo $xml->["@attributes"][0]->["MAP-SETS"] . "<br>";

我说错什么吗？ 我可以从其他xml文件示例中获取其他代码，这些代码不包含特殊字符，例如：“ 

foreach ($movies->movie->characters->character as $character) {


echo $character->name, ' played by ', $character->actor, PHP_EOL;
