SimpleXML
- Введение
- Установка и настройка
- Требования
- Установка
- Настройка во время выполнения
- Типы ресурсов
- Предопределенные константы
- Примеры
- SimpleXMLElement — Класс SimpleXMLElement
- SimpleXMLElement::addAttribute — Добавляет атрибут к SimpleXML-элементу
- SimpleXMLElement::addChild — Добавляет дочерний элемент к узлу XML
- SimpleXMLElement::asXML — Возвращает сформированный XML документ в виде строки используя SimpleXML элемент
- SimpleXMLElement::attributes — Возвращает атрибуты элемента
- SimpleXMLElement::children — Поиск дочерних элементов данного узла
- SimpleXMLElement::__construct — Создание нового SimpleXMLElement объекта
- SimpleXMLElement::count — Считает количество дочерних элементов у текущего элемента
- SimpleXMLElement::getDocNamespaces — Возвращает объявленное пространство имен в документе
- SimpleXMLElement::getName — Получение имени XML элемента
- SimpleXMLElement::getNamespaces — Получение пространств имен, используемых в документе
- SimpleXMLElement::registerXPathNamespace — Создает префикс/пространство имен контекста для следующего XPath запроса
- SimpleXMLElement::saveXML — Псевдоним SimpleXMLElement::asXML
- SimpleXMLElement::__toString — Returns the string content
- SimpleXMLElement::xpath — Запускает XPath запрос к XML данным
- SimpleXMLIterator — Класс SimpleXMLIterator
- SimpleXMLIterator::current — Возвращает текущий элемент
- SimpleXMLIterator::getChildren — Возвращает вложенные элементы текущего элемента
- SimpleXMLIterator::hasChildren — Проверяет, имеет ли текущий элемент вложенные элементы
- SimpleXMLIterator::key — Возвращает текущий ключ
- SimpleXMLIterator::next — Перемещает итератор к следующему элементу
- SimpleXMLIterator::rewind — Возвращает итератор к первому элементу
- SimpleXMLIterator::valid — Проверяет, является ли текущий элемент допустимым
- SimpleXML
- simplexml_import_dom — Получает объект класса SimpleXMLElement из узла DOM.
- simplexml_load_file — Интерпретирует XML-файл в объект
- simplexml_load_string — Интерпретирует строку с XML в объект

Here are two quick and dirty functions that use SimpleXML to detect if a feed xml is RSS or ATOM:
<?php
function is_rss($feedxml) {
@$feed = new SimpleXMLElement($feedxml);
if ($feed->channel->item) {
return true;
} else {
return false;
}
}
function is_atom($feedxml) {
@$feed = new SimpleXMLElement($feedxml);
if ($feed->entry) {
return true;
} else {
return false;
}
