‘'simplexml’php到mysql数据库循环只返回第一个元素

<?php
// 连接到MySQL数据库
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 加载XML文件
$xml = simplexml_load_file('your_xml_file.xml');

// 循环遍历XML元素
foreach ($xml->children() as $element) {
    // 获取元素的属性和值
    $attribute1 = $element->attribute1;
    $attribute2 = $element->attribute2;
    $value = $element->value;

    // 将数据插入到MySQL数据库中
    $sql = "INSERT INTO your_table (attribute1, attribute2, value) VALUES ('$attribute1', '$attribute2', '$value')";
    if ($conn->query($sql) === TRUE) {
        echo "数据插入成功";
    } else {
        echo "数据插入失败: " . $conn->error;
    }

// 关闭数据库连接
$conn->close();
