使用php将非标准xml wsman数据加载到对象中

标签： php xml parsing object wsman

这个问题已经在很多方面得到了回答，但没有一个涉及我的情况。

我使用WSMan提取数据，然后将输出作为一种sudo-xml返回。我甚至不会考虑它＆＃34;真实＆＃34; xml，因为它有很多非标准属性。问题是我需要能够将输出作为PHP中的对象引用。所以目前我使用了很多str_replace。这个问题是，如果非标准格式偏离（在某些情况下，它会返回类似于<KeyID xsi:nil="true"/>的东西，在其他情况下可能会像<CMCIP xsi:nil="true"/>那样），很难预见所有在使用simplexml_load_string将其作为对象导入之前，我必须考虑和拉出变量的不同属性。

所以，我的问题很简单：有没有办法将非标准XML加载到对象中？以下是xml数据的示例，以便您知道我们在这里处理的是什么疯狂。

2 个答案:

答案 0 :(得分：2)

您回复的内容是响应/输出是多个XML文档的串联。在你的例子中，那是两个。

这不是有效的XML，但它并不罕见。

所以你需要做的就是拆分文件并选择你需要处理的文件（在你的例子中是第二个）：

$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]);

由于您现在拥有您感兴趣的XML文档，因此您可以执行许多其他答案建议的有关如何解析SOAP响应的内容。不再存在格式错误的XML（实际上是一系列连接良好的XML文档）。

其余的是处理命名空间。

一些指示：

...获取SOAP信封体：

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

...所有枚举的项目为数组：

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

依此类推。

关于您自己的代码的说明 - 您在答案中给出的示例：如果您要在任何命名空间中查找元素名称，则可以使用local-name()在xpath中执行此操作：< / p> 

$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);
}

它可以帮助你完成五个左右的单独xpath调用。

如果你最终不想像你期望的那样关心命名空间那么一个＆＃34;无论如何，你可以在DOMDocument的帮助下为每个结果创建一个SimpleXMLElement，将每个结果提取到它自己的新文档中：

/**
 * 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);
}

这样的帮助程序是有用的，因为它将元素自己的命名空间作为新SimpleXMLElement的命名空间。这允许直接访问同一名称空间中的子项。进一步使用它的代码不需要关心这个＆＃34;默认＆＃34;命名空间。

示例：

$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);
    }
}

输出：

感谢@Paul Crovella的评论，这实际上让我走上正轨。我最终学到了很多东西。无论如何，解决方案最终成为了事物的组合。这篇文章是最有帮助的，但是：

How do I read SOAP reply Envelope by PHP

对于那些好奇我是如何使它工作的人，我最终编写了一个函数来解析这个问题。为了您的方便，它位于下方。希望这有助于其他人在路上寻找同样的事情！
