Question

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。

<?php
$str = <<<EOT

    <cas:authenticationSuccess>
        <cas:user>zhangjian</cas:user>
        <cas:language></cas:language>
    </cas:authenticationSuccess>
</cas:serviceResponse>
EOT;
 
 $validateXML = simplexml_load_string($str, null, 0, 'cas', true);
print_r($validateXML);$successnode = $validateXML->authenticationSuccess[0];
print_r($successnode); 
$xml = new DOMDocument();
$xml -> loadXML($str);
print_r($xml);SimpleXMLElement Object
(

谢谢唠叨大大，刚刚使用一个方法解决了，不过没有大大的好
$str = <<<EOT
<cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'>
    <cas:authenticationSuccess>
        <cas:user>zhangjian</cas:user>
        <cas:language></cas:language>
    </cas:authenticationSuccess>
</cas:serviceResponse>
EOT;$str = str_replace('cas:', '', $str);
$validateXML = simplexml_load_string($str);
$successnode = $validateXML->authenticationSuccess[0];
echo (string)$successnode->user;
