本文主要介绍PHP 读取和编写 XML的方法,非常的简单实用,给需要的小伙伴们参考下吧

什么是 XML?
XML 是一种数据存储格式。它没有定义保存什么数据,也没有定义数据的格式。XML 只是定义了标记和这些标记的属性。格式良好的 XML 标记看起来像这样:

复制代码 代码如下:


Jack Herrington

DOM读取 XML

复制代码 代码如下:


  $doc = new DOMDocument();
  $doc->load( 'books.xml' );
 
  $books = $doc->getElementsByTagName( "book" );
  foreach( $books as $book )
  {
  $authors = $book->getElementsByTagName( "author" );
  $author = $authors->item(0)->nodeValue;
 
  $publishers = $book->getElementsByTagName( "publisher" );
  $publisher = $publishers->item(0)->nodeValue;
 
  $titles = $book->getElementsByTagName( "title" );
  $title = $titles->item(0)->nodeValue;
 
  echo "$title - $author - $publisher\n";
  }
  ?>

用 DOM 编写 XML

复制代码 代码如下:


  $books = array();
  $books [] = array(
  'title' => 'PHP Hacks',
  'author' => 'Jack Herrington',
  );
  $doc = new DOMDocument(); //创建dom对象
  $doc->formatOutput = true;
 
  $r = $doc->createElement( "books" );//创建标签
  $doc->appendChild( $r );            //将$r标签,加入到xml格式中。
 
  foreach( $books as $book )
  {
      $b = $doc->createElement( "book" );        //创建标签
      $author = $doc->createElement( "author" );
      $author->appendChild($doc->createTextNode( $book['author'] ));  //给标签添加内容
      $b->appendChild( $author );                //将子标签 加入父标签
     
     
      $r->appendChild( $b );                    //加入父标签中!
      }
     
      echo $doc->saveXML();
  ?>

以上就是这2段读取和编写XML的DOM代码了,小伙伴们了解了没,有什么疑问可以给我留言
