我已经在这个问题上待了一个星期左右，并且没有在已经存在的导致解决方案的问题中找到任何信息。我从一家公司（它是一个MITS Feed）中提取了一个非常大的XML文件，它可以轻松超过一百万行输出。遗憾的是，由于法律原因，我无法提供此文件的位置，但我会解释我正在尝试做什么，也许你们都可以帮我解决这个问题。
我正在调用文件：
<?php
$xml=simplexml_load_file("location-of-file/feed.xml");
?>
在此之后，我想要浏览并提取每个属性的信息。这是我们使用的确切模式 -
http://www.mitsproject.com/Content/ServeFile.cfm?FileID=4075
我尝试将其作为DOMDocument导入并以这种方式遍历XML，但没有运气。可能只是一个如何在PHP for循环中拉出所有Property节点的例子就是炸弹。提前谢谢。
P.S。我知道文件至少被抓住了，因为当我跑 -
<?php
$xml = simplexml_load_file("location-of-file/feed.xml", null, LIBXML_NOCDATA);
print_r($xml);
?>
我得到了一个疯狂的大输出。
更新：
以下是一个'Property'作为SimpleXMLElement的示例，也许这会有所帮助 -

答案 0 :(得分：1)
尝试使用
输出Feedecho '<pre>';
print_r($feed);
echo '</pre>';
这应该给你一个更“漂亮”的方案视图以及哪些节点不可访问！
答案 1 :(得分：0)
我建议使用类似的东西：
$xml = simplexml_load_file("location-of-file/feed.xml", null, LIBXML_NOCDATA);
foreach($xml as $key => $item){
// to select an element do something like this
$item->WebSite;
}
但请注意$ item是数组$ xml的副本，因此要操作此对象，您需要将$ item更改为＆amp; $ item，否则您需要在循环中操纵实际值
$test = $item->WebSite;
//do something to $test
$xml->$key->WebSite = $test;
如果您正在构建新的数组/ xml文档，则无需担心此问题
更新
我已经在示例Feed中对此进行了测试，您应该可以通过一些编辑来实现这一点
header("Content-Type: application/xml; charset=utf-8");
$xml = simplexml_load_file("test.xml", null, LIBXML_NOCDATA);
$values = array("Belgian Waffles","French Toast");
$new = new SimpleXMLElement("<tester></tester>");
foreach($xml->food as $item){
if(in_array($item->name,$values)){
$type = $new->addChild('type');
$movie = $type->addChild('movie');
$movie->addChild('price', $item->price);
}else{
}
}
echo $new->asXML();
基本上给这个以前，编辑它以使用正确的节点并为你构建适当的权限然后这应该工作。 asXML（）有一个可选参数，你可以传入它来写文件
因此，将echo $new->asXML();更改为$new->asXML("test.xml");会将文件写入test.xml而不是输出数据。如果你保存它，请确保你摆脱header("Content-Type: application/xml; charset=utf-8");
