Question

我试图使用SimpleXML xpath（）函数从XML文件中提取。我注册了一个新的命名空间，它运行得很好。

$data  = simplexml_load_string('sample.xml');
$data->registerXPathNamespace("a", "http://ns.hr-xml.org/2007-04-15");
$education = $data->xpath("//a:Education"); 
$this->saveEducationData($education);

问题是我如何访问函数内的XML节点？以下代码不起作用。应该再次注册命名空间吗？

function saveEducationData($data = ''){
  $school =  $data->xpath('/a:Institution');
}

任何帮助都将受到高度赞赏。

Answer 1

您可以使用DOMDocument读取XML：

$doc = new DOMDocument();
$doc->loadXML($xmlstr);

$elements = $doc->getElementsByTagName("Education");
$value = $elements->item(0)->nodeValue;

var_dump($value);

其中$ xmlstr是您的XML字符串。

要读取该值，您只需将元素传递给要提取值的函数。
