我知道这已经被问过很多次了,但我无法获得任何适合我的情况的建议,我已经搜索了网络和这里并尝试了一切,但没有任何效果。我只需要使用名称空间 cap: 解析这个 XML:并且只需要其中的四个条目。

我正在使用 simpleXML,并且设置了一个简单的小测试脚本,它非常适合解析常规元素。我无法为我的狄更斯找到或找到一种方法来解析带有名称空间的元素。
这是一个小示例测试脚本,其中包含我正在使用的代码,非常适合解析简单元素。如何使用它来解析命名空间?我尝试过的一切都不起作用。我需要它能够创建变量,以便能够将它们嵌入到 HTML 中以获得样式。
<?php
$html = "";
// Get the XML Feed
$data = "http://alerts.weather.gov/cap/tx.php?x=1";
// load the xml into the object
$xml = simplexml_load_file($data);
for ($i = 0; $i < 10; $i++){
$title = $xml->entry[$i]->title;
$summary = $xml->entry[$i]->summary;
$html .= "<p><strong>$title</strong></p><p>$summary</p><hr/>";
}
echo $html;
?>
这适用于解析常规元素,但是那些在条目父项下带有 cap: 命名空间的元素呢?
<?php
ini_set('display_errors','1');
$html = "";
$data = "http://alerts.weather.gov/cap/tx.php?x=1";
$entries = simplexml_load_file($data);
if(count($entries)):
//Registering NameSpace
$entries->registerXPathNamespace('prefix', 'http://www.w3.org/2005/Atom');
$result = $entries->xpath("//prefix:entry");
//echo count($asin);
//echo "<pre>";print_r($asin);
foreach ($result as $entry):
$title = $entry->title;
$summary = $entry->summary;
$html .= "<p><strong>$title</strong></p><p>$summary</p>$event<hr/>";
endforeach;
endif;
echo $html;
?>
任何帮助将不胜感激。
-谢谢
