php - 我如何从 xml 中获取第一个子元素？

Question

我如何在 PHP 我的代码中从 xml 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:

所以我只想获取第一个元素我该怎么做，有什么建议吗？

Answer 1

除非我误解了这个问题(这是可能的，你不是很清楚)，你有一个遍历所有子元素的循环:

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

将其更改为仅访问第一个子元素非常简单:

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