Question

我正在使用DOMDocument和foreach循环从XML文档中提取数据。数据来自VIN解码器。输入车辆的VIN，然后您将获得有关其的数据。

我苦苦挣扎的方面是，VIN解码器返回了按该车辆样式细分的车辆数据。例如，奥迪S4的VIN返回两种样式：5dr Avant Wgn Man和5dr Avant Wgn Auto。每个样式都有一个ID，应用于该样式的数据也带有该ID。

这是这两种样式的ID结构：
5dr Avant Wgn Man - ID: 292015
5dr Avant Wgn Auto - ID: 292016

以及如何将数据绑定到这些ID的示例：

    <technicalSpecification>
        <titleId>2</titleId>
        <value value="5 Door Wagon" condition="">
           <styleId>292015</styleId>
           <styleId>292016</styleId>
        </value>
     </technicalSpecification>

请注意，5门旅行车适用于两种样式。

我想要实现的是，当我选择5dr Avant Wgn Man时，将显示与该样式相关的所有<technicalSpecification>数据。同样，如果选择5dr Avant Wgn Auto，则将显示与该样式相关的所有数据。

这是XML：

还有我的PHP。该PHP将这两种样式类型放入一个下拉列表中，并打印<technicalSpecification>。我只需要根据在下拉列表中选择的<techhnicalSpecification>来更改style。

<html>
 <body>

  <?php

   $xml = file_get_contents('data.xml');
   $dom = new DOMDocument();
   $dom->loadXML($xml);

  ?>

  <form>
   <select>
    <option selected="selected">Choose style</option>
   <?php
    foreach ($dom->getElementsByTagName('style') as $styleName){
      $styleType = $styleName->getAttribute("name");
      $styleArray[] = $styleType;
     }
    foreach ($styleArray as $style){
     ?>
     <option><?php echo $style;?> </option>
    <?php
     }
    ?>
    </select>
   </form>

   <br>

    <?php

    foreach ( $dom->getElementsByTagName('technicalSpecification') as $techSpec )   {
    $id = $techSpec->getElementsByTagName('titleId')->item(0)->nodeValue;
    $techData [$id]= $techSpec->getElementsByTagName('value')->item(0)->getAttribute("value")."<br>";
     }

    echo "<br><br>";
    print_r($techData);
   ?>

  </body>
 </html>

非常感谢！为您提供帮助！

Answer 1

那是SOAP（不仅仅是XML），因此您应该尝试使用PHP SOAP库。但是，如果您只想将其解析为XML，请查看DOMXpath::evaluate()。它允许您使用Xpath表达式来获取节点（请考虑使用SQL，但要使用XML DOM）。您可以根据属性值选择元素节点：

$xpath = new DOMXpath($document);
foreach ($xpath->evaluate('//technicalSpecification[value/@value="5dr Avant Wgn Man"]') as $specNode) {
   ...
}

基于ID的DOMDocument提取XML数据
