如何高效处理复杂的XML数据？使用alibabacloud/tea-xml让你的PHP应用如虎添翼

<code class="bash">composer require alibabacloud/tea-xml</code>

<code class="xml"><Response>
    <RequestId>ABCD-1234-EFGH</RequestId>
    <Data>
        <Item>
            <Id>1</Id>
            <Name>Product A</Name>
        </Item>
        <Item>
            <Id>2</Id>
            <Name>Product B</Name>
        </Item>
    </Data>
</Response></code>

<code class="php"><?php

require 'vendor/autoload.php';

use AlibabaCloud\Tea\XML\Model\XMLModel;
use AlibabaCloud\Tea\XML\XML; // 假设有一个XML工具类

// 模拟接收到的XML字符串
$xmlString = <<<XML

        </Item>
    </Data>
</Response>

    // 假设XML::parse()可以将XML解析为Tea模型或标准对象/数组
    // 实际使用时，可能需要定义一个继承XMLModel的类来映射XML结构
