Php 子节点名称未知时提取xml数据

Php 子节点名称未知时提取xml数据,php,mysql,xml,child-nodes,Php,Mysql,Xml,Child Nodes,我有一个来自iSpring Solutions的测验系统,它将xml结果数据发送到我的php脚本。我想提取信息来更新mysql数据库 每个测验都有不同的问题,因此xml文件的长度/结构并不总是相同的,但是我需要获得特定的数据 下面是xml文件的摘录 <questions> <matchingQuestion id="{3F033905-566A-4B67-B7E4-324E4367FD16}" status="correct" maxPoints="2" maxAtt

将左侧的项目与右侧的项目匹配
哪一个不定冠词应该写在下面的单词“a”或“an”前面?
我需要 (a) 获取每个子节点的名称/id (b) 获取id、状态、maxPoints值 (c) 然后得到“方向”值

节点名称“matchingQuestion”或“FillingBlankQuestionEx”总是根据测验的不同而改变顺序

我不知道如何获得这些值,因为每个测验的问题类型都不同

非常感谢

约翰

要开始编码,我举一个例子。假设,$text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/>';
}

感谢您的回复,我使用了下面的代码,从Splash58重新编写了更新mysql数据库的php:


但是,数据库中只添加了第一个问题。

请编辑您的问题,并提供您作为起点的代码。我自己尝试过:)-在第二种情况下,$QuestionAsked包含引号,您应该使用mysql\u real\u escape\u string()好哇!像做梦一样工作!非常感谢你!

Which indefinite article should be written in front of the following words - 'a' or 'an'? 
    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);

}
