我正在尝试从XML文件中检索XML数据，当我使用children（）时，我希望它会检索子节点的数据，但它不会检索。在以下XML文件中

我使用了以下PHP代码来打印这个数据
$fileloc = "../qjfiles/c2014-2.001.xml";
$filedata = new SimpleXMLElement(file_get_contents($fileloc));
foreach ($filedata->Notes->children() as $filexmldata) {
echo $filexmldata->children()."<br/>";
}
输出显示如下
The second respondent by virtue of the extended definition of “foreign state†in s 3(3) of the Act.

如何分别显示<Note id="f1"和<Note id="f2"的输出？
我试过像$filexmldata->Note[1]->children()一样，但它不起作用
这个问题的答案
How can I display the output of <Note id="f1" separately and <Note id="f2" separately?
您可以使用xpath方法。下面是一个关于如何获取包含id="f2"的节点的示例：
$xml = simplexml_load_string($xml);
$node = $xml->xpath('/Notes/Note[@id="f2"]');
您可以替换下面的php代码并尝试吗
<?php
$fileloc = "../qjfiles/c2014-2.001.xml";
$filedata = new SimpleXMLElement(file_get_contents($fileloc));
foreach ($filedata as $filexmldata) {
foreach($filexmldata->attributes() as $a=> $b) {
echo $a,'="',$b,"'"'n";
}
echo '<pre>'; print_r($filexmldata->P);
}
?>
