<&#63;php
 $xml = "";
 $f = fopen('person.xml', 'r');
 while($data = fread($f,4096)){
  $xml .= $data;
 }
 fclose( $f );
// 上面读取数据
 preg_match_all("/\<humans\>(.*&#63;)\<\/humans\>/s",$xml,$humans); 
//匹配最外层标签里面的内容
 foreach( $humans[1] as $k=>$human )
 {
  preg_match_all("/\<name\>(.*&#63;)\<\/name\>/",$human,$name);
//匹配出名字
  preg_match_all("/\<sex\>(.*&#63;)\<\/sex\>/",$human,$sex);
//匹配出性别
  preg_match_all("/\<old\>(.*&#63;)\<\/old\>/",$human,$old);
//匹配出年龄
 }
foreach($name[1] as $key=>$val){
