PHP cURL，提取 XML 响应

Question

我在服务器上调用 PHP cURL 方法，响应是 XML 类型。 cURL 将输出(删除标签后)保存在标量类型变量中。有没有办法将它存储在对象/哈希/数组中以便于解析？

<?php
function download_page($path){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$path);
    curl_setopt($ch, CURLOPT_FAILONERROR,1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 15);
    $retValue = curl_exec($ch);          
    curl_close($ch);
    return $retValue;
}

$sXML = download_page('http://alanstorm.com/atom');
$oXML = new SimpleXMLElement($sXML);

foreach($oXML->entry as $oEntry){
    echo $oEntry->title . "\n";
}
