php读取xml文件的xml实例代码

作者：袖梨 2022-06-24

代码如下

复制代码

class dom
{
  protected $_dom = null;

  public function __construct($xmlfile = '',$ver = '',$encoding = '')
  {
    $this -> _dom = ($ver && $encoding)? new domdocument($ver,$encoding):new domdocument();
    $xml = !$xmlfile?file_get_contents('php://input'):file_get_contents($xmlfile);
    $this -> _dom -> loadxml($xml);
  }

  public function getvalue($nodename)
  {
    $nodes = $this -> _dom -> getelementsbytagname($nodename);
    return null !== $nodes -> item(0)?$nodes -> item(0) -> nodevalue:false;
  }
}

//本xml类代码是利用了php domdocument来解析xml文档 ?>
