Question

我一直在尝试从Google日历中提取此XML文件中的数据，而对命名空间的内容却没有太大成功。

这只是我遇到问题的gd和gCal数据 - 我搜索了所有内容并且无法让它工作：（

任何帮助表示赞赏！：）

到目前为止，PHP代码是：

<?php
$source = "data2.xml";
$xmlstr = file_get_contents($source);
$parseXMLFile = new SimpleXMLElement($xmlstr);
echo $parseXMLFile->id[0];
echo "<br>";
echo $parseXMLFile->title[0];
echo "<br>";
echo $parseXMLFile->content[0];
?>

基本上它建议使用xPath调用，例如

$xml = new SimpleXMLElement($r);

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

使用php解析xml命名空间
