PHP SimpleXML获得价值

<?xml version="1.0" encoding="UTF-8"?>
<languages>
    <language lan="de">
        <lanString key="siteTitle">Simple engine DE</lanString>
    </language>
    <language lan="en">
        <lanString key="siteTitle">Simple engine EN</lanString>
        <lanString key="welcomeText">Welcome to Simple engine</lanString>
    </language>
</languages>

How can i access the value of lanString with the key: "siteTitle" I have tried it with the following:

public function getString($key, $lan){
    return $this->mXmlFile->xpath('language[@lan="'.$lan.'"]/lanString[@key="'.$key.'"]');
}

But there is no output :(

    The following code, using the same XML that you provided and the same call to xpath(), works well:

    function getString($xml, $key, $lan){
      return $xml->xpath('language[@lan="'.$lan.'"]/lanString[@key="'.$key.'"]');
    }
    
    $data = '<?xml version="1.0" encoding="UTF-8"?>
      <languages>
        <language lan="de">
          <lanString key="siteTitle">Simple engine DE</lanString>
      </language>
      <language lan="en">
          <lanString key="siteTitle">Simple engine EN</lanString>
          <lanString key="welcomeText">Welcome to Simple engine</lanString>
      </language>
    </languages>';
    
    $xml = new SimpleXMLElement($data);
    
    print_r(getString($xml, "siteTitle", "de"));
    

    For the sake of simplicity, I changed the method into a simple function. It prints out:

    Array
    (
        [0] => SimpleXMLElement Object
            (
                [@attributes] => Array
                    (
                        [key] => siteTitle
                    )
    
                [0] => Simple engine DE
            )
    )
    

    So I think the code that you provided is OK. If it doesn't show any output, the issue might be somewhere else...
