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

.....
<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>

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]);

PHP code
 $s=<<<html
<span class="singer" style="width: 95px;">
<a href="artist/001">json</a>
</span>
.....
<span class="singer" style="width: 95px;">

<span class="singer" style="width: 95px;">
<a href="artist/003">php</a>
<span>/</span>
<a href="artist/004">mysql</a>
</span>
html;

 $s= str_replace('<span>/</span>','',$s);
preg_match_all('/<span class="singer"[^>]*>(.*)<\/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);
