當子節點名稱未知時提取xml數據

Question

我有一個來自iSpring Solutions的測驗系統，它將xml結果數據發送到我的php腳本。我想提取信息來更新一個mysql數據庫。

每個測驗都有不同的問題，所以xml文件並不總是相同的長度/結構，但是我需要獲取特定的數據。

這裏是從XML文件

<questions> 

    <matchingQuestion id="{3F033905-566A-4B67-B7E4-324E4367FD16}" status="correct" maxPoints="2" maxAttempts="1" awardedPoints="2" usedAttempts="1"> 
     <direction>Match the items on the left with the items on the right</direction> 
    </matchingQuestion> 

    <fillInTheBlankQuestionEx id="{6FCC5DAC-168F-4F44-87DF-9B1D162268D1}" status="partially" maxPoints="8" maxAttempts="1" awardedPoints="4" usedAttempts="1"> 
     <direction>Which indefinite article should be written in front of the following words - 'a' or 'an'?</direction> 
    </fillInTheBlankQuestionEx> 

    </questions> 

我需要 （一）獲取每個子節點的名稱/ ID提取 （B）得到的ID，狀態，maxPoints值 （C ）然後得到'方向'值

節點名稱'matchingQuestion'或'fillInTheBlankQuestionEx'總是根據測驗改變順序。

我不知道如何獲取這些值，因爲每個測驗的問題類型都不相同！

提前感謝

Answer 1

要開始在作弄我，我展示一個例子。假設，$文本包含XML

$xml = new SimpleXMLElement($text); 
echo '<pre>'; 
foreach ($xml->questions->children() as $q) { 
//  print_r($q); echo '<br/>'; 
     print_r((string)$q->getName());echo '<br/>'; 
     print_r((string)$q->attributes()->id);echo '<br/>'; 
     print_r((string)$q->direction);echo '<br/>'; 
} 

結果：

matchingQuestion 
{3F033905-566A-4B67-B7E4-324E4367FD16} 
Match the items on the left with the items on the right 
fillInTheBlankQuestionEx 
{6FCC5DAC-168F-4F44-87DF-9B1D162268D1} 
Which indefinite article should be written in front of the following words - 'a' or 'an'? 

Answer 2

謝謝您的回覆，我用下面的代碼，從Splash58重新寫正在更新MySQL數據庫的PHP：

foreach ($xml->questions->children() as $q) { 
$QuestionType=(string)$q->getName(); 
$QuestionUUID=(string)$q->attributes()->id; 
$QuestionAsked=(string)$q->direction; 

$query="INSERT INTO questions (UUID, Qtype, Question) VALUES ('".$QuestionUUID."', '".$QuestionType."', '".$QuestionAsked."')"; 
$mysqli->query($query); 

} 

但是，只有第一個問題被添加到數據庫。
