使用php將非標準xml wsman數據加載到對象中

Question

此問題已在許多變體中得到解答，但沒有一個涉及到我的情況。

我拉數據使用WSMan，然後返回輸出作爲一種sudo-xml。我甚至不認爲它是「真正的」XML，因爲它有很多非標準的屬性。問題是我需要能夠在PHP中將輸出引用爲對象。所以目前我正在使用很多str_replace。問題在於，如果非標準格式有偏差（在某些情況下，它會返回類似<KeyID xsi:nil="true"/>的其他情況，它可能類似於此類<CMCIP xsi:nil="true"/>），因此很難預見我要前往的所有不同屬性在使用simplexml_load_string將其作爲對象導入之前，必須考慮並拉出變量。

所以，我的問題在所有簡單：有沒有辦法將非標準的XML加載到對象？以下是xml數據的示例，以便您知道我們在這裏處理的是什麼瘋狂。

Answer 1

作爲響應/輸出得到的是多個XML文檔的連接。在你的例子中有兩個。

這不是有效的XML，但它也並不少見。

因此，所有你需要做的是分裂的文件，並選擇你需要要處理的一個（在例子中的第二）：

$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]); 

正如你現在有your're XML文檔感興趣的是，您可以做所有其他答案就如何解析SOAP響應提出的建議。沒有任何格式不正確的XML（實際上是一系列格式良好的XML文檔）。

其餘的是處理命名空間。

一些指針：

...得到SOAP信封體：

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

...所有列舉的項目，如數組：

$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。

在自己的代碼，例如一個音符你給你的答案是：如果你在任何命名空間中尋找一個元素的名稱，你可以用local-name()做到這一點在XPath中：

$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); 
} 

那確實讓你有五個左右的xpath調用。

如果您最終不希望關心名稱空間，因爲您希望它是每個項目的「那一個」，您可以在DOMDocument的幫助下爲每個結果創建一個SimpleXMLElement，方法是將每個結果抽取爲一個它自己的新文件：

/** 
* 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); 
} 

這種輔助程序是有幫助的，因爲它把元素的自己的名字空間的命名空間，新的SimpleXMLElement。這允許直接訪問同一名稱空間中的子項。進一步使用它的代碼將不需要關心這個「默認」命名空間。

例子：

$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); 
    } 
} 

輸出：

謝謝@Paul Crovella的評論，這實際上讓我走上了正軌。我最終學到了很多東西。無論如何，解決方案最終都是結合在一起的。這個職位是最幫助，但是：
