file_get_contents第二波！正则匹配很欢乐

问题是这样的 file_get_contents 出来的内容是这样.....

<a href="artist/001">json</a>

.....

<a href="artist/002">ajax</a>

....

<a href="artist/003">php</a>
/
<a href="artist/004">mysql</a>
我想得到的结果是array("json","ajax","php+mysql");
求正则正则实在是心头的一块隐痛.....

$s = <<< TXT
.....

<a href="artist/001">json</a>

.....

<a href="artist/002">ajax</a>

....

<a href="artist/003">php</a>
/
<a href="artist/004">mysql</a>

TXT;preg_match_all("/<span.+<a.+>(.+)</isU", $s, $r);
print_r($r[1]);Array
(
 [0] => json
 [1] => ajax
 [2] => php
 [3] => mysql
)至于 array("json","ajax","php+mysql"); 就不是正则能胜任的了
先拜谢了呵呵我想只匹配 class="singer"的span /(.+)</isU这样对吗
$s=<<<html

<a href="artist/001">json</a>

.....

<a href="artist/002">ajax</a>


<a href="artist/002">ajax</a>

....

<a href="artist/003">php</a>
/
<a href="artist/004">mysql</a>

html; $s= str_replace('/','',$s);
preg_match_all('/]*>(.*)<\/span>/isU',$s,$m);
foreach($m[1] as $v){
 $v=preg_replace('/<[^>]+>/','',$v,-1,$count);
 if($count>2) $arr[]=join('+',preg_split("/[\r\n]+/",$v,-1,PREG_SPLIT_NO_EMPTY));
 else
 $arr[]=trim($v);
}
print_r($arr); Array
(
 [0] => json
 [1] => ajax
 [2] => php+mysql
)
preg_match_all("/(.+)</isU", $s, $r);
