XML/PHP 到数组的问题答案

【问题描述】：

我已经为此烦恼了几个小时，想把它贴在这里看看是否有人有任何建议。

基本上，我通过 SOAP/Curl 调用接收一些 XML 日期，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <LocationAvailabilityResponse xmlns="">

我正在尝试遍历每个酒店的酒店结果并将每个结果转换为多维数组。我正在使用的代码无法正常工作，如下所示：

$doc = new DOMDocument(); 


if ($doc->loadXML($result)) { 
$items = $doc->getElementsByTagName('hotels'); 
$hotelnames = array();

foreach($items as $item) { 
    $hotelname = array(); 
    $hotelimages = array();

    if($item->childNodes->length) { 
        foreach($item->childNodes as $i) {

            $hotelname[$i->nodeName] = $i->nodeValue; 

            if($i->childNodes->length){

                foreach($i->childNodes as $z) {

                    if($z->childNodes->length){

                        foreach($z->childNodes as $x) {

                            $hotelimage[$x->nodeName] = $x->nodeValue;

                        }

                    }



                }

            }

            $hotelimages[] = $hotelimage;
        } 
    } 

    $hotelnames[] = $hotelname; 
} 

}

我猜我面临的问题主要是由于子节点和父节点对于酒店和图像的命名相同。

我们将不胜感激任何对正确方向的帮助或点头。

标签： php xml arrays multidimensional-array

【解决方案1】：

我建议您使用xpath（例如在SimpleXML 实现中http://php.net/manual/en/simplexmlelement.xpath.php）来加载您需要的值。

或者如果您需要将整个 XML 解析为数组，您可以随时使用 PEAR XML_Serializer 包 (http://pear.php.net/package/XML_Serializer) 来反序列化您的 XML。

【解决方案2】：

我建议您不要直接使用 DOM，除非您确实需要访问 DOM，否则请使用 SimpleXML 执行这些任务

它使处理 XML 数据变得非常容易，您几乎可以像处理普通数组一样对其进行操作。

例子

<?php 
  $url = 'http://www.flickr.com/services/feeds/photos_public.gne';   

  foreach(simplexml_load_file($url)->entry as $entry) {
    echo $entry->content; 
  }
?>

该功能的几行代码:)

祝你好运！

【讨论】：

感谢您的回复，所以理论上这应该有效，但由于某种原因它不起作用： foreach(simplexml_load_string($result)->hotels as $entry) { echo $entry->hotels; }
您的酒店标签不在根目录下。您将它包含在必须首先访问的多个其他节点中。您可以按照与上述相同的方式执行此操作，但需要多个步骤$xml->node1->node1Child1->data，或者您可以使用children() 函数来提取hotels 标记。还有xpath() 函数可以让你对你的xml 执行xpath 搜索。如果您熟悉 xpath，这很可能是最优雅的解决方案。

【解决方案3】：

我正在查看 XML，我注意到一些 XML 标记不正确 Ex: <images><images></images><images></images></images> roomunit 也是如此。

我认为它应该像<images><image></image><image></image></images> 这将有助于在 php 中迭代 XML 标记。
