这个问题已经在许多变化已经回答了，但他们没有提到我的情况。

我使用的WSMan，然后返回输出作为一种须藤-XML的拉动数据。 我甚至不认为这是“真正”的XML，因为它有许多不规范的属性。 的问题是，我需要能够引用输出作为内PHP的对象。 所以目前我使用了很多str_replace函数的。 这样做的问题是，如果非标准格式偏离（在某些情况下，它会返回这样的事情<KeyID xsi:nil="true"/>在其他情况下，它可能是这样的<CMCIP xsi:nil="true"/>它是很难预见所有的不同属性，我将不得不考虑和导入它作为使用simplexml_load_string一个对象之前拔出可变的。

所以，我在所有简单的问题：有没有办法来加载非标准XML到对象？ 这里是XML数据的样本，让你知道我们这里处理什么疯狂。

Answer 1:

你获得了作为响应/输出多个XML文档的串联。 在您的例子这是两个。

这不是有效的XML，但它也并不少见。

因此，所有你需要做的是分裂的文件，并选择你需要要处理（在你的例子第二）之一： 

$split = preg_split('~\Q<?xml version="1.0" encoding="UTF-8"?>\E\R~u', $sequenced_xml, 2, PREG_SPLIT_NO_EMPTY);
$xml   = simplexml_load_string($split[1]);

正如你现在有XML文档your're兴趣，你可以做什么都很多其他的答案如何解析SOAP响应建议。 有没有畸形XML（实际上是串联简洁（wellformed）XML文档的顺序）的任何更长的时间。

其余的正在处理的命名空间。

一些指针：

...得到SOAP信封体： 

$soap = 'http://www.w3.org/2003/05/soap-envelope';
$body = $xml->children($soap)->Body;

......所有的列举项目为数组： 

$wsen = 'http://schemas.xmlsoap.org/ws/2004/09/enumeration';
$xml->registerXPathNamespace('wsen', $wsen);
$items = $body->xpath('.//wsen:*/*[not(namespace-uri(.) = namespace-uri(..))]');

等等等等。

在你自己的代码，例如一个音符你给你的答案是：如果你在任何命名空间中寻找一个元素的名称，你可以做到这一点在XPath的local-name() 

$pullitem = 'ServiceTag';
$try      = $xml->xpath(sprintf("//*[local-name(.)='%s']", $pullitem));

printf("pullitem '%s' has been foun in the following namespaces:\n", $pullitem);
foreach ($try as $element) {
    $nsURI = dom_import_simplexml($element)->namespaceURI;
    printf(" - %s\n", $nsURI);
}

该作备用您在五年左右的个人XPath的电话。

如果你终于不希望因为你希望它是每个项目的“那一个”反正关心的命名空间，你可以用DOM文档的帮助下各提取到一个新的文件是为每个结果一个SimpleXMLElement拥有： 

/**
 * create a new SimpleXMLElement out of an existing one
 *
 * @param SimpleXMLElement $item
 *
 * @return SimpleXMLElement
 */
function simplexml_export_element(SimpleXMLElement $item) {
    $doc  = new DOMDocument();
    $node = $doc->importNode(dom_import_simplexml($item), true);
    $node = $doc->appendChild($node);
    return simplexml_load_string($doc->saveXML($doc->documentElement), get_class($item), 0, $node->namespaceURI);
}

这种辅助程序是有帮助的，因为它把元素的自己的名字空间的命名空间，新的SimpleXMLElement。 这允许直接访问的孩子在同一个命名空间。 进一步使用它的代码将不再需要关心这个“默认”的命名空间明确。

例： 

$split = preg_split('~\Q<?xml version="1.0" encoding="UTF-8"?>\E\R~u', $sequenced_xml, 2, PREG_SPLIT_NO_EMPTY);

$xml  = new SimpleXMLElement($split[1]);

$soap = 'http://www.w3.org/2003/05/soap-envelope';
$body = $xml->children($soap)->Body;

$wsen = 'http://schemas.xmlsoap.org/ws/2004/09/enumeration';
$xml->registerXPathNamespace('wsen', $wsen);

$enumerated = $body->xpath('.//wsen:*/*[not(namespace-uri(.) = namespace-uri(..))]');
$enumerated = array_map('simplexml_export_element', $enumerated);

foreach ($enumerated as $item) {
    echo $item->getName(), "\n";
    foreach ($item as $key => $value) {
        printf(" - %s: %s\n", $key, $value);
    }
}
