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
<br /><cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'><br /> <cas:authenticationSuccess><br /> <cas:user>zhangjian</cas:user><br /> <cas:language></cas:language><br /> </cas:authenticationSuccess><br /></cas:serviceResponse><br />
于是使用php相关函数进行解析
$str = <<
/*
$validateXML = simplexml_load_string($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。

怎么会？
<br /><?php<br />$str = <<<EOT<br /><cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'><br /> <cas:authenticationSuccess><br /> <cas:user>zhangjian</cas:user><br />
