使用SimpleXML使用命名空间解析XML [英] Parse XML with Namespace using SimpleXML

问题描述

我将其作为xml:

<root xmlns:event="http://www.webex.com/schemas/2002/06/service/event">
    <event:event>
        <event:sessionKey></event:sessionKey>
        <event:sessionName>Learn QB in Minutes</event:sessionName>
        <event:sessionType>9</event:sessionType>
        <event:hostWebExID></event:hostWebExID>
        <event:startDate>02/12/2009</event:startDate>
        <event:endDate>02/12/2009</event:endDate>
        <event:timeZoneID>11</event:timeZoneID>
        <event:duration>30</event:duration>
        <event:description></event:description>
        <event:status>NOT_INPROGRESS</event:status>
        <event:panelists></event:panelists>
        <event:listStatus>PUBLIC</event:listStatus>
    </event:event>
    ...
</root>

如何遍历所有event:event节点并显示例如所有event:SessionKey?

How can I loop through all of the event:event nodes and display, for example, all of the event:SessionKey's?

这不起作用:

$xml = new SimpleXMLElement($r);
$xml->registerXPathNamespace('e', 'http://www.webex.com/schemas/2002/06/service/event');

foreach($xml->xpath('//e:event') as $event) {
 var_export($event->xpath('//e:sessionKey'));
}

推荐答案

在没有registerXPathNamespace和xpath查询中的完整名称空间前缀的情况下，它确实可以工作:

it does work without registerXPathNamespace and the full namespace prefix in the xpath queries:

$xml = new SimpleXMLElement($r);

foreach($xml->xpath('//event:event') as $event) {
 var_export($event->xpath('event:sessionKey'));
}
