在PHP中导入XML以添加到Mysql数据库

我一直在试图破解这个，但就是没能破解

基本上，我有一个包含列车时刻表信息的XML文件，它非常复杂

我需要捕获每一点信息并添加到MySQL数据库中，但正如您将看到的，父/子和键/对是非常动态的，有时它有更多或更少的内容

我一直在寻找SimpleXML，但无法从XML中获取值，因为它可以灵活地适应信息/数据的变化

请注意，从第一次旅行到第二次旅行，有新的字段，正如您可能猜到的，它需要捕获

如何获取以下XLM内部的元素：

以及每种元素，如：

OR作为其他值也非常重要

非常感谢

实验性PHP代码：

<?php
$xml = simplexml_load_file($argv[1]) or die("Error: Cannot create object");
//
//  TimeTableID
//
$timetableId = $xml->attributes()->timetableID;
echo "Timetable id: " . $timetableId . "\n\r";
//
// Journey
// I've added the atributes->
foreach ($xml->Journey as $Journey) {
    echo "Journey data: " . $Journey["rid"] . "\n\r";
    echo "Journey data: " . $Journey["uid"] . "\n\r";
    echo "Journey data: " . $Journey["trainId"] . "\n\r";
    echo "Journey data: " . $Journey["ssd"] . "\n\r";
    echo "Journey data: " . $Journey["toc"] . "\n\r";
}
?>

感谢您的贡献。我从SimpleXML搬到了xmlReader

这就是我如何回答我自己的问题的方式，可能并不圆滑，但它正在发挥作用：

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {

// open the file for reading
$xmlReader->open($argv[1]);

// Inittiate var
$rid = "";
$sql_table_name = "";
$number_of_inserts = 0;
    while ($xmlReader->read()) { 
        // check to ensure nodeType is an Element not attribute or #Text

考虑MySQL的

加载XML

功能，它可以将XML数据直接导入数据库，类似于

加载CSV

。但是，您需要扁平化和简化XML以适应不同的需求。幸运的是，有一个很好的工具可以用来转换这样一种以属性为中心的XML:，这是一种专门用于转换XML文件以满足最终使用需求的专用语言。PHP可以用它的类运行XSLT1.0脚本

特别是下面的XSLT提取所有

属性。如果它们作为根节点的子节点驻留，则可以将XSLT中的旅程更改为其他路径：Association、main等。当然，确保您的MySQL目标表具有来自XML的所有可能字段

XSLT（另存为.xsl文件）

PHP（无循环或if语句）

//加载XML和XSL源
$doc=新的DOMDocument（）；
$doc->load（'Input.xml'）；
$xsl=新文档；
$xsl->load（'XSLT_Script.xsl'）；
//配置变压器
$proc=新的XSLTProcessor；
$proc->importStyleSheet（$xsl）；
//变换源
$newXml=$proc->transformToXML（$doc）；
//保存到文件
文件内容（'Output.xml'，$newXml）；
//运行MYSQL命令（可能需要在设置中允许--local infle）
试一试{
$conn=newmysqli（$servername、$username、$password、$dbname）；
$conn->query（“加载XML数据填充'path/to/Output.XML'
进桌之旅
由“；”标识的行；
}捕获（例外$e）{
echo$e->getMessage（）；
}
$conn->close（）；

XML（转换后的输出传递到加载XML）
