php - 如何使用 php 从 xml 文件（树结构）中检索节点

Question

我有以下 XML 树：

<?xml version="1.0" encoding="utf-8"?>

<root>
    <start_info>
            <info tabindex="1">
            <infonumber>1</infonumber>
            <trees>green</trees>
            </info>
    </start_info>
    <people>
        <pe>
            <people_ages>
                <range number="1">
                    <age value="1">1</age>
                    <age value="2">2</age>
                </range>
            </people_ages>
        </pe>
    </people>
</root>

首先，我必须在复选框中显示所有节点，然后必须在提交文件时检索它们的节点值。我必须使用 PHP 来完成。

OR
