Question

我试图用我从大型XML文件解析的数据来构建关联数组。问题是数组只输出一个循环。我无法使用所有相关节点循环来构建它。

XML结构如下：

<?xml version="1.0" encoding="utf-8"?>
<root>
    ...
    <property>
        ...
        <images>
            <image id="1">
                <url>https://example.com/image1.jpg</url>
                <title>
                    <en>en_lang_translation</en>
                    <es>es_lang_translation</es>
                    <de>de_lang_translation</de>
                </title>
            </image>
            <image id="2">
                <url>https://example.com/image2.jpg</url>
                <title>
                    <en>en_lang_translation</en>
                    <es>es_lang_translation</es>
                    <de>de_lang_translation</de>
                </title>
            </image>
        </images>
        ...
    </property>
    ...
</root>

...到目前为止我所获得的代码如下：

foreach($property->childNodes as $nodename) {

    if($nodename->nodeName == 'images') {

        $imageArray = array();

        foreach($nodename->childNodes as $imageNodes) {

            foreach($imageNodes->childNodes as $imageSubNodes) {

                if($imageSubNodes->nodeName == 'url') {

                    $imageArray['url'] = $imageSubNodes->nodeValue;

                } else if($imageSubNodes->nodeName == 'title') {

                    foreach($imageSubNodes->childNodes as $titleNode) {

                        foreach($titleNode->childNodes as $titleLangNode) {

                            $childs = $titleNode->childNodes;
                            $key = $titleNode->nodeName;

                            foreach ($childs as $p) {

                                $imageArray[$key] = $p->nodeValue;

                            }
                        }
                    }
                }
            }
        }
    }
}

破解了。下面的评论（谢谢你们）指出了我的解决方案。我在每次循环运行时都覆盖了数组。我回到绘图板并简化了foreach循环，因为那是我出错的地方，在多个循环中迷路了。我的固定代码如下：

while(is_object($property = $doc->getElementsByTagName("property")->item($i))) {

    foreach($property->childNodes as $nodename) {

        if($nodename->nodeName=='images') {

            foreach($nodename->childNodes as $images) {

                if($images->nodeName == 'image') {
                    //now in each images node - children are image
                    foreach($images->childNodes as $image) {
                        //now in each image node - children are url & title
                        if($image->nodeName == 'url'){
                            $image_url = $image->nodeValue;
                        }
                        if($image->nodeName == 'title'){
                            foreach($image->childNodes as $title) {
                                // now in title node - children en, es, de
                                if($title->nodeName == 'en'){
                                    $title_en = $title->nodeValue;
                                }
                                if($title->nodeName == 'es'){
                                    $title_es = $title->nodeValue;
                                }
                                if($title->nodeName == 'de'){
                                    $title_de = $title->nodeValue;
                                }
                            }
                        }                       
                    }
                }
                $imageArray[] = array('url' => $image_url, 'title_en' => $title_en, 'title_es' => $title_es, 'title_de' => $title_de);
            }

        } 
    }

    $i++;
}
echo '<ul>';
foreach ($imageArray as $key => $value) {
    echo '<li>'.$value['url'].' - '.$value['title_en'].'</li>';
}
echo '</ul>';

或者，考虑使用零循环，if逻辑或数组，仅XSLT将源XML转换为HTML列表项：

XSLT （另存为.xsl脚本，格式正确的.xml文件）

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output indent="yes" method="xml"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="/root">
    <ul>
      <xsl:apply-templates select="property"/>
    </ul>
  </xsl:template>  

  <xsl:template match="property|images">    
      <xsl:apply-templates select="*"/>    
  </xsl:template>

  <xsl:template match="image">    
      <li><xsl:value-of select="concat(url, ' - ', title/en)"/></li>
      <li><xsl:value-of select="concat(url, ' - ', title/es)"/></li>
      <li><xsl:value-of select="concat(url, ' - ', title/de)"/></li>
  </xsl:template>

</xsl:stylesheet>

<强> PHP

// LOAD XML AND XSL SOURCES
$xml = new DOMDocument;
$xml->load('Input.xml');

$xsl = new DOMDocument;
$xsl->load('XSLTScript.xsl');

// CONFIGURE TRANSFORMER
$proc = new XSLTProcessor;
$proc->importStyleSheet($xsl);

// TRANSFORM XML 
$newXML = new DOMDocument;
$newXML = $proc->transformToXML($xml);

echo $newXML;   // <--- STRING OUTPUT

// <ul>
//    <li>https://example.com/image1.jpg - en_lang_translation</li>
//    <li>https://example.com/image1.jpg - es_lang_translation</li>
//    <li>https://example.com/image1.jpg - de_lang_translation</li>
//    <li>https://example.com/image2.jpg - en_lang_translation</li>
//    <li>https://example.com/image2.jpg - es_lang_translation</li>
//    <li>https://example.com/image2.jpg - de_lang_translation</li>
// </ul>

XML数组循环仅循环
