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

PHP code

array("json","ajax","php+mysql");

求正则正则实在是心头的一块隐痛.....

------解决方案--------------------

PHP code

$s = <<< TXT.....<span class="singer" style="width: 95px;"><a href="artist/001">json</a></span>.....<span class="singer" style="width: 95px;"><a href="artist/002">ajax</a></span>....<span class="singer" style="width: 95px;"><a href="artist/003">php</a><span>/</span><a href="artist/004">mysql</a></span>TXT;preg_match_all("/<span.+<a.+>(.+)</isU", $s, $r);print_r($r[1]);
