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！！！


回复讨论(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？ 

&lt;?php$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;  $validateXML = simplexml_load_string($str, null, 0, 'cas', true);print_r($validateXML);$successnode = $validateXML->authenticationSuccess[0];print_r($successnode); $xml = new DOMDocument();$xml -> loadXML($str);print_r($xml);</pre>  <pre class="sycode" name="code">SimpleXMLElement Object(    [authenticationSuccess] => SimpleXMLElement Object        (            [user] => zhangjian            [language] => SimpleXMLElement Object                (                )        ))SimpleXMLElement Object(    [user] => zhangjian    [language] => SimpleXMLElement Object        (        ))DOMDocument Object(    [doctype] =>     [implementation] => (object value omitted)    [documentElement] => (object value omitted)    [actualEncoding] =>     [encoding] =>     [xmlEncoding] =>     [standalone] => 1    [xmlStandalone] => 1    [version] => 1.0    [xmlVersion] => 1.0    [strictErrorChecking] => 1    [documentURI] => file:///D:/AMP/web/    [config] =>     [formatOutput] =>     [validateOnParse] =>     [resolveExternals] =>     [preserveWhiteSpace] => 1    [recover] =>     [substituteEntities] =>     [nodeName] => #document    [nodeValue] =>     [nodeType] => 9    [parentNode] =>     [childNodes] => (object value omitted)    [firstChild] => (object value omitted)    [lastChild] => (object value omitted)    [previousSibling] =>     [attributes] =>     [ownerDocument] =>     [namespaceURI] =>     [prefix] =>     [localName] =>     [baseURI] => file:///D:/AMP/web/    [textContent] =>             zhangjian            )</pre> </p> <p class="sougouAnswer">  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  <br />  <br />  <pre class="sycode" name="code">$str = <<<EOT<cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'>    <cas:authenticationSuccess>        <cas:user>zhangjian</cas:user>        <cas:language></cas:language>    </cas:authenticationSuccess></cas:serviceResponse>EOT;$str = str_replace('cas:', '', $str);$validateXML = simplexml_load_string($str);$successnode = $validateXML->authenticationSuccess[0];echo (string)$successnode->user;</pre> </p> </article >
