通过PHP将不规则XML导入MySQL

我希望你能帮忙。我有一个xml文件要导入到MySQL表中。不幸的是，它不是一个标准的XML文件。有关格式，请参见以下内容：

这里有一个黑客。它只是基本上完成了XML文件

<?php
$conn = mysqli_connect("localhost", "root", "test", "info");

$affectedRow = 0;

$file_contents = sprintf("%s</CounterNotification> </DDCCommonData>",file_get_contents("input.xml"));

$xml = simplexml_load_string($file_contents) or die("Error: Cannot create object");

foreach ($xml->children() as $row) {
    $MachineModel = $row->MachineModel ;
    $SerialNumber= $row->SerialNumber;

    $sql = "INSERT INTO counts(MachineModel ,SerialNumber) VALUES ('" . $MachineModel . "','" . $SerialNumber. "')";

    $result = mysqli_query($conn, $sql);

    if (! empty($result)) {
        $affectedRow ++;
    } else {
        $error_message = mysqli_error($conn) . "\n";
    }
}

您的表结构设计得非常糟糕，不建议像这样存储重复的数据，相反，我建议像

CREATE TABLE counts (
    id int(9) NOT NULL auto_increment,
    modelname varchar(255) NULL,
    serialnumber varchar(255) NULL,
    counter_color varchar(255) NULL,
    counter_type varchar(255) NULL,
    counter_small varchar(255) NULL,
    counter_large varchar(255) NULL
    PRIMARY KEY (id)
) ENGINE=InnoDB;

然后，您可以读取每个计数器元素，并使用颜色和类型属性，将其直接存储到表中，而不是拥有一个巨大的表

$xml = simplexml_load_file("NewFile.xml") or die("Error: Cannot create object");

$sql = "INSERT INTO counts(MachineModel ,SerialNumber, counter_color, counter_type
            counter_small, counter_large) 
    VALUES (?,?,?,?,?,?)";
$stmt = mysqli_prepare($conn, $sql) or die(mysqli_error($conn));

foreach ($xml->CounterNotification as $row) {
    $MachineModel = $row->MachineModel ;
    $SerialNumber= $row->SerialNumber;

    echo $MachineModel."/".$SerialNumber.PHP_EOL;
    foreach ( $row->ChargeCounter->Counter as $counter )    {
        mysqli_stmt_bind_param($stmt, "ssssss", $MachineModel, $SerialNumber,
            $counter['Color'], $counter['Type'], $counter->Small, $counter->Large);
        $result = mysqli_execute($stmt);
        if (! empty($result)) {
            $affectedRow ++;
        } else {
            $error_message = mysqli_error($conn) . "\n";
        }
    }
}

无论如何，您可以添加到XML文件的末尾吗？没有不规则的。只有有效和无效。这是后者。@jbrahy是的，我可以将其添加到XML文件的末尾。你能帮忙吗？谢谢，但我希望每个大的和小的列$counter->large和$counter->small都是单独的值，如果我不知道你想要的列，除了显示值，我应该如何处理它们。我更新了原始帖子，请看一看。谢谢。在很多情况下，OP可能发布了更大文件的一部分。因此，尽管这可能有助于读取样本数据，但它并没有解决读取其他数据的主要问题。

CREATE TABLE counts (
    id int(9) NOT NULL auto_increment,
    modelname varchar(255) NULL,
    serialnumber varchar(255) NULL,
    counter_color varchar(255) NULL,
    counter_type varchar(255) NULL,
    counter_small varchar(255) NULL,
    counter_large varchar(255) NULL
    PRIMARY KEY (id)
) ENGINE=InnoDB;

$xml = simplexml_load_file("NewFile.xml") or die("Error: Cannot create object");

$sql = "INSERT INTO counts(MachineModel ,SerialNumber, counter_color, counter_type
            counter_small, counter_large) 
    VALUES (?,?,?,?,?,?)";
$stmt = mysqli_prepare($conn, $sql) or die(mysqli_error($conn));

foreach ($xml->CounterNotification as $row) {
    $MachineModel = $row->MachineModel ;
    $SerialNumber= $row->SerialNumber;

    echo $MachineModel."/".$SerialNumber.PHP_EOL;
    foreach ( $row->ChargeCounter->Counter as $counter )    {
        mysqli_stmt_bind_param($stmt, "ssssss", $MachineModel, $SerialNumber,
            $counter['Color'], $counter['Type'], $counter->Small, $counter->Large);
        $result = mysqli_execute($stmt);
        if (! empty($result)) {
            $affectedRow ++;
        } else {
            $error_message = mysqli_error($conn) . "\n";
        }
    }
}
