1.DOMDocument方法
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";
 echo "
";
 }
 ?>
 
2.用 SAX 解析器读取 XML
 

 
3.用正则表达式解析 XML
 
(.*?)\<\/book\>/s", $xml, $bookblocks );
  
 foreach( $bookblocks[1] as $block )
 {
 preg_match_all( "/\(.*?)\<\/author\>/", $block, $author );
 preg_match_all( "/\(.*?)\<\/title\>/",   $block, $title );
 preg_match_all( "/\(.*?)\<\/publisher\>/", $block, $publisher );
 echo( $title[1][0]." - ".$author[1][0]." - ".$publisher[1][0]."\n" );
 }
 ?>
 
4.解析XML到数 组
 
简单的XML数据";
     $parser = xml_parser_create();                        //创建解析器
     xml_parse_into_struct($parser, $data, $values, $index);    //解析到数组
     xml_parser_free($parser);                            //释放资源
      
     //显示数组结构
     echo "\n索引数组\n";
     print_r($index);
     echo "\n数据数组\n";
     print_r($values);
 ?>
 
5.检查XML是否有效
 
";
  
         //输出错误行，列及其错误信息
         $error_line   = xml_get_current_line_number($xml_parser);
         $error_row   = xml_get_current_column_number($xml_parser);
         $error_string = xml_error_string(xml_get_error_code($xml_parser));
  
         $message = sprintf("［第%d行，%d列］：%s", 
                         $error_line,
                         $error_row,
                         $error_string);
         echo $message;
     }
     else
     {
         echo "该XML文档是结构良好的。";
     }
      
     //关闭XML解析器指针，释放资源
     xml_parser_free($xml_parser);
 ?>

2.PHP中的生成XML文件的4种方法
【前言】
使用PHP怎么创建XML文件呢？
一直以来都是使用别人封装好的类，没有自己尝试过，难得放几天假，于是自己总结了下。使用PHP生成XML文件的4种常见方法如下：
