php解析cas返回的xml解决思路
时间：2021-07-01 10:21:17
帮助过：12人阅读
php解析cas返回的xml
使用php进行cas验证时，对方返回这么一段xml
zhangjian
于是使用php相关函数进行解析
$str = <<
zhangjian
EOT;
/*
$validateXML = simplexml_load_string($str);print_r($validateXML);
$successnode = $validateXML->authenticationSuccess[0];
var_dump($successnode);
*/
$xml = new DOMDocument();
$xml -> loadXML($str);
var_dump($xml);
结果都解析不出来，哪位朋友遇到过请指点下，不甚感激！！！
------解决方案--------------------SimpleXML也是PHP5后提供的一套简单易用的xml工具集，
不过它不适用于包含namespace（命名空间）的xml。
------解决方案--------------------怎么会？
