用PHP读取XML。 不起作用(命名空间)

I can read XML files or strings but not the next:

$str = <<<XML
    <Output xmlns="nice.uniform://" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
        <Data i:nil="true"/>
        <Result xmlns:a="http://nice.uniform/CLSAPI3">
        <Exception i:nil="true" xmlns:a="http://schemas.datacontract.org/2004/07/System"/>

My PHP code to read a node of XML file is:

$Output = new SimpleXMLElement($str);
echo $Output->Result->{'a:ResultCodeEx'};

Also, I've tried:

$xmlResponse = simplexml_load_file('file.xml');
foreach($xmlResponse->Result as $xmlEntry)
 echo $xmlEntry->{'a:ResultCodeEx'};


$blocks = $xmlResponse->xpath('//Output');

Can you help me?

    The document uses several namespaces. The element ResultCodeEx belongs to the namespace a. You can use XPath, but you need to register the namespace a before the query:

    $Output = new SimpleXMLElement($str);
    $Output->registerXPathNamespace ('a', 'http://nice.uniform/CLSAPI3');
    $result =  $Output->xpath('//a:ResultCodeEx/text()');
    echo $result[0]; // CLS_SE_SUCCESS
