Я знаю, что это было задано много раз, но я не смог получить какие-либо предложения по работе с моей ситуацией, и я искал в Интернете, а здесь и пробовал все, и ничего, и ничего не работает. Мне просто нужно проанализировать этот XML с крышкой пространства имен и просто нужно четыре записи из него.

Я не могу, чтобы мои дикки нашли или попытались разобрать элементы с пространствами имен.
Вот небольшой тестовый скрипт с кодом, который я использую, и отлично работает для синтаксического анализа простых элементов. Как это использовать для анализа пространств имен? Все, что я пробовал, не работает. Мне нужно это, чтобы иметь возможность создавать переменные, чтобы я мог встраивать их в HTML для стиля.
<?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; ?>
Это отлично подходит для разбора регулярных элементов, но как насчет тех, у кого есть cap: namespace под родительским элементом?
<?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; ?>
Любая помощь будет принята с благодарностью.
-Благодаря
Я дал такой же ответ здесь – решение вашего вопроса
Вам просто нужно зарегистрировать пространство имен, а затем вы можете нормально работать с файлами simplexml_load_file и XPath
<?php $data = "http://alerts.weather.gov/cap/tx.php?x=1"; $entries = file_get_contents($data); $entries = new SimpleXmlElement($entries); if(count($entries)): //echo "<pre>";print_r($entries);die; //alternate way other than registring NameSpace //$asin = $asins->xpath("//*[local-name() = 'ASIN']"); $entries->registerXPathNamespace('prefix', 'http://www.w3.org/2005/Atom'); $result = $entries->xpath("//prefix:entry"); //echo count($asin); //echo "<pre>";print_r($result);die; foreach ($result as $entry): //echo "<pre>";print_r($entry);die; $dc = $entry->children('urn:oasis:names:tc:emergency:cap:1.1'); echo $dc->event."<br/>"; echo $dc->effective."<br/>"; echo "<hr>"; endforeach; endif;
Вот и все.
Вот альтернативное решение:
