我如何从xml获取第一个子元素？

我如何从PHP中的xml中获取第一个子元素：

    $xmlPath = 'www.example.com/file.xml';
    $fileContents= file_get_contents($xmlPath);

    $fileContents = str_replace(array("\n", "\r", "\t", "<br>"), '', $fileContents);
      $fileContents = trim(str_replace('"', "'", $fileContents));
      $simpleXml = simplexml_load_string($fileContents);
      $xmlArray = array();
      foreach($simpleXml->children() as $child) {
        $xmlArray [] = array(
          'parent' => $child->getName(),
        );
        foreach($child->children() as $subchild) {
          $xmlArray[] = array(
            'child' => $subchild->getName()
          );
        }
      }

XML代码：

所以,我只想获得第一个要素,我有什么建议吗？

解决方法:

除非我对这个问题有误解(可能是,您不太清楚),否则所有子元素都有一个循环：

foreach($simpleXml->children() as $child) {

将其更改为仅访问第一个子元素确实很简单：

$children = $simpleXml->children();
$first_child = $children[0];
