【问题描述】：

我尝试使用此页面中的一些脚本用于我的网上商店。我想将一个 XML 文件导入我的 MySQL 数据库。我得到了脚本工作，但只导入了第一个订单行，而不是第二个。

这是我的 XML 代码示例：

<?xml version="1.0" encoding="UTF-8"?>
<eWebBooking>
   <OrderHead>
      <Action>SendFromWarehouse</Action>
      <OrderReference>5986-20193315</OrderReference>
      <EarliestOrderDate/>
      <OrderNumber>20193315</OrderNumber>
      <SalesOrg>Web</SalesOrg>
      <DistChannel>Parcel</DistChannel>
      <InvoiceReference>Reknes</InvoiceReference>
      <Orderer>
         <Name>Ola Nordamann</Name>
         <Telephone>22225555</Telephone>
         <Email/>
         <StreetName>Hackerstreet 46</StreetName>
         <PostalCode>5986</PostalCode>
         <Region>LEGOLAND</Region>
      </Orderer>
   </OrderHead>


   <OrderLines>
      <OrderLine>1</OrderLine>
      <ArticleNo>10501</ArticleNo>
      <ArticleDescription>MPOW Dunmer Earphone Blueth</ArticleDescription>
      <ArticleBrand>MPOW</ArticleBrand>
      <DlvDate>2016-09-09</DlvDate>
      <NoOfPieces>1</NoOfPieces>
      <DeliveryStore>eWeb</DeliveryStore>
      <DeliveryCode>DELIVERY</DeliveryCode>
      <Weight>0,2</Weight>
      <Volume>70</Volume>
      <ShipmentNo>73600698093661246</ShipmentNo>
      <ParcelNo>373600596034663364</ParcelNo>
   </OrderLines>
   <OrderLines>
      <OrderLine>2</OrderLine>
      <ArticleNo>10528</ArticleNo>
      <ArticleDescription>Mpow MBS5 Armor Bluetooth</ArticleDescription>
      <ArticleBrand>MPOW</ArticleBrand>
      <DlvDate>2016-09-07</DlvDate>
      <NoOfPieces>1</NoOfPieces>
      <DeliveryStore>eWeb</DeliveryStore>
      <DeliveryCode>PICKUP</DeliveryCode>
      <Weight>4</Weight>
      <Volume>50</Volume>
      <ShipmentNo>73600698093661246</ShipmentNo>
      <ParcelNo>00373600698636066394</ParcelNo>
    </OrderLines>
</eWebBooking>

我想我必须更改一些 foreach 代码？
这是我的 PHP 文件/代码的副本：

<?php

ini_set('display_errors','On');

$con2 = mysql_connect("databasehost","databaseuser","databasepass");
if (!$con2)  {  
    die('Could not connect: ' . mysql_error());  
}

$selectdb = mysql_select_db("databasename", $con2);
if (!$selectdb)  { 
    die('Database not used: ; ' . mysql_error());  
}

$file_arr = array();

if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) {
        if (($file != ".") && ($file != "..")) {
            if(substr($file, -4) == ".xml")
            {
                array_push($file_arr, $file);
            }
        }
    }
    closedir($handle);
}

    foreach($file_arr as $filename)

{
     $xml = simplexml_load_file($filename);

    $Action = mysql_real_escape_string($xml->OrderHead->Action);
    $OrderReference = mysql_real_escape_string($xml->OrderHead->OrderReference);    
    $EarliestOrderDate = mysql_real_escape_string($xml->OrderHead->EarliestOrderDate);
    $OrderNumber = mysql_real_escape_string($xml->OrderHead->OrderNumber);
    $SalesOrg = mysql_real_escape_string($xml->OrderHead->SalesOrg);
    $DistChannel = mysql_real_escape_string($xml->OrderHead->DistChannel);
    $InvoiceReference = mysql_real_escape_string($xml->OrderHead->InvoiceRefernce);
    $Name = mysql_real_escape_string($xml->OrderHead->Orderer->Name);
    $Telephone = mysql_real_escape_string($xml->OrderHead->Orderer->Telephone);
    $Email = mysql_real_escape_string($xml->OrderHead->Orderer->Email);
    $StreetName = mysql_real_escape_string($xml->OrderHead->Orderer->StreetName);
    $PostalCode = mysql_real_escape_string($xml->OrderHead->Orderer->PostalCode);
    $Region = mysql_real_escape_string($xml->OrderHead->Orderer->Region);


    $OrderLine = mysql_real_escape_string($xml->OrderLines->OrderLine);
    $ArticleNo = mysql_real_escape_string($xml->OrderLines->ArticleNo);
    $ArticleDescription = mysql_real_escape_string($xml->OrderLines->ArticleDescription);
    $ArticleBrand = mysql_real_escape_string($xml->OrderLines->ArticleBrand);
    $DlvDate = mysql_real_escape_string($xml->OrderLines->DlvDate);
    $NoOfPieces = mysql_real_escape_string($xml->OrderLines->NoOfPieces);
    $DeliveryStore = mysql_real_escape_string($xml->OrderLines->DeliveryStore);
    $DeliveryCode = mysql_real_escape_string($xml->OrderLines->DeliveryCode);
    $Weight = mysql_real_escape_string($xml->OrderLines->Weight);
    $Volume = mysql_real_escape_string($xml->OrderLines->Volume);
    $ShipmentNo = mysql_real_escape_string($xml->OrderLines->ShipmentNo);
    $ParcelNo = mysql_real_escape_string($xml->OrderLines->ParcelNo);
    $TimeWindowStart = mysql_real_escape_string($xml->OrderLines->TimeWindowStart);
    $TimeWindowEnd = mysql_real_escape_string($xml->OrderLines->TimeWindowEnd);


    mysql_query("INSERT INTO xml (Action, OrderReference, EarliestOrderDate, OrderNumber, SalesOrg, DistChannel, InvoiceReference, Name, Telephone, Email, StreetName, PostalCode, Region, OrderLine, ArticleNo, ArticleDescription, ArticleBrand, DlvDate, NoOfPieces, DeliveryStore, DeliveryCode, Weight, Volume, ShipmentNo, ParcelNo, TimeWindowStart, TimeWindowEnd)
    VALUES ('$Action', '$OrderReference', '$EarliestOrderDate', '$OrderNumber', '$SalesOrg', '$DistChannel', '$InvoiceReference', '$Name', '$Telephone', '$Email', '$StreetName', '$PostalCode', '$Region', '$OrderLine', '$ArticleNo', '$ArticleDescription', '$ArticleBrand', '$DlvDate', '$NoOfPieces', '$DeliveryStore', '$DeliveryCode', '$Weight', '$Volume', '$ShipmentNo', '$ParcelNo', '$TimeWindowStart', '$TimeWindowEnd')")
    or die(mysql_error());


    printf ("Records inserted: %d\n", mysql_affected_rows());  
    echo " <p />--- --- --- --- --- --- --- --- ---<p />";
}

mysql_close($con2);

?>

【问题讨论】：

请停止使用mysql_* 函数。它们在 PHP 5.5 中被弃用，它太旧了，甚至不再接收安全更新，并在 PHP 7 中完全删除。相反，使用mysqli_* 或 PDO。见stackoverflow.com/questions/12859942/…
如果你这样做foreach ($xml->OrderLines as $order)怎么办？
在发布的 XML 中，<TimeWindowStart> 或 <TimeWindowEnd> 没有节点。

【解决方案1】：

考虑使用 MySQL 的 LOAD XML LOCAL INFILE 批量导入 XML 文档。但是，要使用此命令，您的 XML 必须简化以与数据库字段和值对齐。要为此类导入重构原始文档，请考虑XSLT（用于操作源文档的 XML 转换语言）。 XSLT 可以将原始 XML 转换为更简单、更扁平的数据库上传结构。 PHP 使用libxslt 引擎维护一个 XSLT 1.0 处理器。

XSLT 脚本（另存为.xsl 文件以便在下面的PHP 中读取）

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output version="1.0" encoding="UTF-8" indent="yes" />
<xsl:strip-space elements="*"/>

  <xsl:template match="/eWebBooking">
     <xsl:copy>
        <xsl:apply-templates select="OrderLines"/>
     </xsl:copy>
  </xsl:template>

  <xsl:template match="OrderLines"> 
   <xsl:copy>          
       <xsl:copy-of select="ancestor::eWebBooking/OrderHead/*[not(local-name()='Orderer')]"/>
       <xsl:copy-of select="ancestor::eWebBooking/OrderHead/Orderer/*"/>
       <xsl:copy-of select="*"/>
   </xsl:copy>
  </xsl:template>    
</xsl:transform>

PHP脚本（以下使用PDO连接MySQL；你可能需要在MYSQL中启用php_xsl扩展并设置-local-infile）

$file_arr = array();

if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) {
        if (($file != ".") && ($file != "..")) {
            if(substr($file, -4) == ".xml")
            {
                array_push($file_arr, $file);
            }
        }
    }
    closedir($handle);
}

foreach($file_arr as $filename) {

     // LOAD XML AND XSL SOURCES
     $doc = simplexml_load_file($filename);
     $xsl = simplexml_load_file('XSLTScript.xsl');

     // TRANSFORM SOURC
     $proc = new XSLTProcessor;
     $proc->importStyleSheet($xsl); 
     $newDoc = $proc->transformToXML($doc);

     // SAVE OUTPUT TO FILE         
     $xmlfile = 'temp.xml';
     file_put_contents($xmlfile, $newDoc);

     // RUN MYSQL COMMAND 
     try {
        $db = new PDO('mysql:host=databasehost;dbname=databasename', 
                      $databaseuser, $databasepwd); 
        $db->query("LOAD XML DATA INFILE 'path/to/temp.xml'
                    INTO TABLE xml
                    ROWS IDENTIFIED BY '<OrderLines>';");
     } catch(PDOException $e) {  
            echo $e->getMessage(); 
     } 
}

转换后的 XML （要导入 db，所有元素名称必须与数据库名称匹配）

【讨论】：

@IanBrindley - 太棒了！如果解决方案比 OP 更有帮助，尤其是未来的读者，那就更好了。
它解决了我的问题，但是运行MYSQL COMMAND时它不会向我的数据库输入数据。
您收到的异常/错误是什么？如前所述，元素名称是否与数据库表字段名称完全匹配？使用循环的 temp.xml 输出之一，并像 MySQL 控制台一样在 PHP 之外运行此命令。
