使用以下符号来迭代您的 xml（更改“myfile.xml”和“tagName”）：

<?php
include('simple_html_dom.php');
if (file_exists('myfile.xml')) {
    $xml = simplexml_load_file('myfile.xml');
    print_r($xml);
    foreach( $xml->children() AS $child ) {
        $name = $child->getName();
        if ($name == 'tagName') {
            foreach( $child->children() AS $grandchild ) {
                // DO SOMETHING
            }
        }
    }
}
?>

还有其他更优雅的方法来实现此目的，但这是一个简单的初学者方法。有关技术信息： https://www.php.net/manual/en/类.simplexmlelement.php

use the following notation to iterate thru your xml (change 'myfile.xml' and 'tagName'):

<?php
include('simple_html_dom.php');
if (file_exists('myfile.xml')) {
    $xml = simplexml_load_file('myfile.xml');
    print_r($xml);
    foreach( $xml->children() AS $child ) {
        $name = $child->getName();
        if ($name == 'tagName') {
            foreach( $child->children() AS $grandchild ) {
                // DO SOMETHING
            }
        }
    }
}
?>

there are other more elegant ways to achieve this, but this is a simple beginner's way to do it. for technical info: https://www.php.net/manual/en/class.simplexmlelement.php
