将两个 txt 文件转换为单个 XML 文件

【问题标题】：Convert two txt files to single XML File将两个 txt 文件转换为单个 XML 文件
【发布时间】：2020-03-20 01:55:25
【问题描述】：

我每天收到两个文本文件。一个有车辆信息，另一个有经销商信息。我将下面的脚本取消 XMLWriter 以将它们转换为 xml。有没有办法使用一个公共节点将两个 txt 文件解析为一个 XML 文档？公共节点是 FRANCHISE_ID。

我使用以下脚本将它们转换为 xml：

<?php
$data = fopen('dealers_retail.txt', 'r');
    $xml = new XMLWriter;
    $xml->openURI('dealers_retail.xml');
    $xml->setIndent(true); // makes output cleaner
    $xml->startElement('DATA');
    $flag = true;
    while ($line = fgetcsv($data, 0, '|')) {
        if($flag) { $flag = false; continue; }
       $xml->startElement('ITEM');
       $xml->writeElement('FRANCHISE_ID', $line[0]);
       $xml->writeElement('FRANCHISE_NAME', str_replace("~", "", $line[1]));
       $xml->writeElement('FRANCHISE_ADDRESS', str_replace("~", "", $line[2]));
       $xml->writeElement('FRANCHISE_CITY', str_replace("~", "", $line[3]));
       $xml->writeElement('FRANCHISE_STATE', str_replace("~", "", $line[4]));
       $xml->writeElement('FRANCHISE_ZIP', str_replace("~", "", $line[5]));
       $xml->endElement();
    }
    $xml->endElement();
?>

哪些输出：

<DATA>
 <ITEM>
  <FRANCHISE_ID>12345</FRANCHISE_ID>
  <FRANCHISE_NAME>Mercedes-Benz of XXX</FRANCHISE_NAME>
  <FRANCHISE_ADDRESS>2915 Some Street</FRANCHISE_ADDRESS>
  <FRANCHISE_CITY>Oakland</FRANCHISE_CITY>
  <FRANCHISE_STATE>CA</FRANCHISE_STATE>
  <FRANCHISE_ZIP>94611</FRANCHISE_ZIP>

</DATA>

我尝试了以下方法，仅将经销商数据复制到属于该经销商的第一辆车。我不知道如何将它应用于特定经销商的每辆车：

<?php

$data = fopen('usacarshopucr_used_inventory_retail.txt', 'r');
// Skip header
fgetcsv($data, 0, '|');
$xml = simplexml_load_string("<DATA />");
// Array which translates the field name to the field in the input file
$itemData = ['FRANCHISE_ID' => 0, 'VEHICLE_VIN' => 1, 'LISTING_ID' => 1,
    'LIST_PRICE' => 2, 'VEHICLE_YEAR' => 3,
    'MAKE_DESC' => 4, 'MODEL_DESC' => 5
];

while ($line = fgetcsv($data, 0, '|')) {
    $item = $xml->addChild("ITEM");
    // Copy the data from the input file to the XML
    foreach ( $itemData as $name => $itemElement )   {
        $item->addChild($name, str_replace("~", "", $line[$itemElement]));
    }
}

$data = fopen('usacarshopucr_used_dealers_retail.txt', 'r');
fgetcsv($data, 0, '|');

// You will need to add all of the fields in here, this is just to show
// how to start.  Don't add the fields with a fixed value, these are added
// in separately
$itemData = ['FRANCHISE_NAME' => 1,
    'FRANCHISE_ADDRESS' => 2, 'FRANCHISE_CITY' => 3,
    'FRANCHISE_STATE' => 4, 'FRANCHISE_ZIP' => 5
];
while ($line = fgetcsv($data, 0, '|')) {
    // Find the matching item in the existing XML for the FRANCHISE_ID
    $item = $xml->xpath('//ITEM[FRANCHISE_ID="'.$line[0].'"]')[0];
    // Copy the data from the input file to the XML
    foreach ( $itemData as $name => $itemElement )   {
        $item->addChild($name, str_replace("~", "", $line[$itemElement]));
    }

    // Add in fixed data - again finish this part off
    $item->addChild('CONDITION_RADIO', 'used');
    $item->addChild('ADF_CONDITION', 'used');
}
$xml->asXML('simple_inventory_retail-2.xml');

?>

它输出：

    【解决方案1】：

    这使用 SimpleXML 来创建文件，而不是尝试合并输出，这将在一个过程中读取经销商文件，从那里创建详细信息，然后读取库存文件并将详细信息添加到...

    （更新为将经销商读取到数组中，然后将详细信息一次性写入 XML 文件）。

    $data = fopen('dealers_retail.txt', 'r');
// Skip header
fgetcsv($data, 0, '|');

// Store dealer information
$dealers = [];
while ($line = fgetcsv($data, 0, '|')) {
    $dealers [$line[0]] = $line;
}
fclose($data);

$xml = simplexml_load_string("<Data />");

$data = fopen('inventory_retail.txt', 'r');
fgetcsv($data, 0, '|');

$dealerData = ['FRANCHISE_ID' => 0, 'FRANCHISE_NAME' => 1,
    'FRANCHISE_ADDRESS' => 2, 'FRANCHISE_CITY' => 3,
    'FRANCHISE_STATE' => 4, 'FRANCHISE_ZIP' => 5
];

// You will need to add all of the fields in here, this is just to show
// how to start.  Don't add the fields with a fixed value, these are added
// in separately
$itemData = ['VEHICLE_VIN' => 1, 'LISTING_ID' => 1,
    'LIST_PRICE' => 2, 'VEHICLE_YEAR' => 3,
    'MAKE_DESC' => 4, 'MODEL_DESC' => 5
];
while ($line = fgetcsv($data, 0, '|')) {
    // Add in dealer data
    $item = $xml->addChild("ITEM");
    $dealer = $dealers[$line[0]];
    foreach ( $dealerData as $name => $itemElement )   {
        $item->addChild($name, str_replace("~", "", $dealer[$itemElement]));
    }
    // Copy the data from the vehicle file to the XML
    foreach ( $itemData as $name => $itemElement )   {
        $item->addChild($name, str_replace("~", "", $line[$itemElement]));
    }

    // Add in fixed data - again finish this part off
    $item->addChild('CONDITION_RADIO', 'used');
    $item->addChild('ADF_CONDITION', 'used');
}
$xml->asXML('inventory_retail.xml');

    【讨论】：

    • 嗨，有没有办法在每个相应的库存项目中发布经销商数据？当前，数据仅复制到第一个 ITEM。
    【解决方案2】：

    我建议先将 CSV 文件导入数据库。如果您没有数据库服务器，请使用 SQLite。您可能可以为此使用一些 CLI 工具。在 PHP 脚本中，您可以收集多个数据项并一次插入它们以平衡内存和 CPU 使用率。

    拥有数据库后，您可以轻松地使用 JOIN 来获取聚合结果并使用 XMLWriter 输出 XML。

    此外，您还可以生成过滤或有限的结果。

    【讨论】：

    • 您好，这样可以将经销商数据复制到每辆车吗？
    • SQL 允许连接表以产生结果：SELECT * FROM listings, franchises WHERE franchises.franchise_id = listings.franchise_id
    • 您好，谢谢您的帮助。
    【解决方案3】：

    是的，您可以将 2 个传入文件中的 2 个数组合并为一个，然后才创建 xml 文件。

    $flag = true;

$mergedArray = [];  // this array will contain all data
// insert data from first file
while ($line = fgetcsv($data_from_first_file, 0, '|')) {
    if($flag) { $flag = false; continue; }
     $mergedArray[$line[0]]['FRANCHISE_ID'] = $line[0];
     // and so on ...

}
// insert data from second file
$flag = true;

while ($line = fgetcsv($data_from_second_file, 0, '|')) {
    if($flag) { $flag = false; continue; }
     $mergedArray[$line[0]]['VEHICLE_VIN'] =  str_replace("~", "", $line[1]);
     // and so on ...

}
// now just foreach over the array to create the XML
// ...
$xml = new XMLWriter;
$xml->openURI('dealers_retail.xml');
$xml->setIndent(true);
$xml->startElement('DATA');

foreach($mergedArray as $item=>$data){
    $xml->startElement('ITEM');
    foreach($data as $index=>$value){
       $xml->writeElement($index, $value);
    }
   $xml->endElement();
}
$xml->endElement();

    • 您好，感谢您的帮助。这会为每个经销商创建一个 xml 文件，并包含一辆车。在 txt 文件中，有 141 个经销商和 140,000 辆汽车。我试图操纵它以在 xml 文件中显示每辆车，但也包括车辆 中的经销商信息
