使用DOMDocument提取XML值

标签: php xml soap domdocument

我有一个XML格式的Soap Envelope响应,我正在尝试从中提取数据。我已经成功提取了一些数据点;但是,我正在与一对夫妇奋斗。到目前为止,除了DOMDocument函数之外,我还使用了getElementsbyTagName()

我正在尝试提取<technicalSpecification>数据。主要是“奥迪S4”,“ 5门旅行车”,“全轮驱动”,“小型旅行车”和“ 5.0”。

这是XML(note.xml):

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">

        </value>
     </technicalSpecification>
     <technicalSpecification>
        <titleId>7</titleId>
        <value value="Small Station Wagon" condition="">
           <styleId>292015</styleId>
           <styleId>292016</styleId>
        </value>
     </technicalSpecification>
     <technicalSpecification>
        <titleId>8</titleId>
        <range min="5.0" max="5.0"/>
        <value value="5" condition="">
           <styleId>292015</styleId>
           <styleId>292016</styleId>
        </value>
     </technicalSpecification>
  </VehicleDescription>

这是我的PHP:

<html>
 <body>

  <?php

  $xml = file_get_contents('note.xml');

  $dom = new DOMDocument();
  $dom->loadXML($xml);


  $id = $dom->getElementsByTagName('WorldManufacturerIdentifier')->item(0);
  $vin = $dom->getElementsByTagName('titleId')->item(0);

  echo $id->textContent;
  echo "<br>";
  echo $vin->textContent;


  ?>

 </body>
</html>

这将返回:

Germany Audi Nsu
1

我理想的回报是:

Germany Audi Nsu
Audi S4
5 Door Wagon
All-Wheel Drive
Small Station Wagon
5.0

任何有关如何调用这些technicalSpecification变量的想法都很棒。非常感谢!

我现在正尝试从“外部颜色”部分中提取数据。我很亲近我希望输出如下所示:

常用颜色名称-技术颜色名称
就像这样:

红色-艳红
黑色-亮黑色

以下是“外部颜色”输出的XML:

     <exteriorColor colorCode="A2A2" colorName="Brilliant Black" rgbValue="131313">
        <genericColor name="Black" primary="true"/>
        <styleId>292015</styleId>
        <styleId>292016</styleId>
     </exteriorColor>
     <exteriorColor colorCode="C8C8" colorName="Brilliant Red" rgbValue="D23637">
        <genericColor name="Red" primary="true"/>
        <styleId>292015</styleId>
        <styleId>292016</styleId>
     </exteriorColor>
     <exteriorColor colorCode="8A8A" colorName="Deep Sea Blue Pearl" rgbValue="0F172A">
        <genericColor name="Blue" primary="true"/>
        <styleId>292015</styleId>
        <styleId>292016</styleId>
     </exteriorColor>
     <exteriorColor colorCode="F5F5" colorName="Dolphin Gray Metallic" rgbValue="53575F">
        <genericColor name="Gray" primary="true"/>
        <styleId>292015</styleId>
        <styleId>292016</styleId>
     </exteriorColor>
     <exteriorColor colorCode="T9T9" colorName="Ibis White" rgbValue="F4F5EF">
        <genericColor name="White" primary="true"/>
        <styleId>292015</styleId>
        <styleId>292016</styleId>
     </exteriorColor>
     <exteriorColor colorCode="1T1T" colorName="Imola Yellow" rgbValue="FFE242">
        <genericColor name="Yellow" primary="true"/>
        <styleId>292015</styleId>
        <styleId>292016</styleId>
     </exteriorColor>
     <exteriorColor colorCode="5B5B" colorName="Light Silver Metallic" rgbValue="A4A5A7">
        <genericColor name="Gray" primary="false"/>
        <genericColor name="Silver" primary="true"/>
        <styleId>292015</styleId>
        <styleId>292016</styleId>
     </exteriorColor>
     <exteriorColor colorCode="L8L8" colorName="Phantom Black Pearl" rgbValue="000000">
        <genericColor name="Black" primary="true"/>
        <styleId>292015</styleId>
        <styleId>292016</styleId>
     </exteriorColor>
     <exteriorColor colorCode="5N5N" colorName="Sprint Blue Pearl" rgbValue="1F3986">
        <genericColor name="Blue" primary="true"/>
        <styleId>292015</styleId>
        <styleId>292016</styleId>
     </exteriorColor>

到目前为止,这是我的PHP:

$finalColor = [];
foreach ($dom->getElementsByTagName('exteriorColor') as $exColor){
   $genColor = $exColor->getElementsByTagName('genericColor')->item(0)->getAttribute("name");
   $colorNames = $exColor->getAttribute("colorName");
   $finalColor = $genColor."- ".$colorNames;
 }
   print_r($finalColor);
   echo "<br>";

这仅检索最后一种颜色,而不检索整个数组。对其进行了一段时间的调整,但没有成功。有什么想法吗?

1 个答案:

答案 0 :(得分:1)

您可以使用与已有的想法相同的方法-使用getElementsByTagName()来获取<technicalSpecification>元素的列表,然后在其中提取<value>元素。使用元素的->getAttribute("value")提取之后的值。

foreach ( $dom->getElementsByTagName('technicalSpecification') as $techSpec )   {
    echo $techSpec->getElementsByTagName('value')->item(0)->getAttribute("value");
    echo "<br>";
}

哪个输出...

Audi S4<br>5 Door Wagon<br>All-Wheel Drive<br>Small Station Wagon<br>5<br>

唯一的事情是最后一个值是5而不是5.0,因为它与其他项目不在同一字段中。

更新

您可以使用<titleId>值作为索引,并使用上面提取的值作为反对值来存储所有这些数据。因此,只需在构建过程中建立一个数组即可。

$techData = [];
foreach ( $dom->getElementsByTagName('technicalSpecification') as $techSpec )   {
    $id = $techSpec->getElementsByTagName('titleId')->item(0)->nodeValue;
    $techData [$id]= $techSpec->getElementsByTagName('value')->item(0)->getAttribute("value");
}
print_r($techData);
echo $techData[7];

这给你...

Array
(
    [1] => Audi S4
    [2] => 5 Door Wagon
    [6] => All-Wheel Drive
    [7] => Small Station Wagon
    [8] => 5
)
Small Station Wagon

您可以使用XPath进行相同的操作,但是如果您使用多个字段,则以这种方式(IMHO)做起来可能会更容易。
