哪位高手帮改个正则

谁帮改个正则？
这是要匹配的内容：

 

<br />
<dl><br />
	<dt>2013</dt><br />
	<dd>row1</dd><br />
	<dd>row2</dd><br />
	<dd>row3</dd><br />
</dl><br />
<dl><br />
	<dt>2014</dt><br />
	<dd>row1</dd><br />
	<dd>row2</dd><br />
</dl><br />

要匹配dl，并且匹配dl下的dt,和所有的dd,

我是这样写的：

<dl>\s+<dt>(.*?)</dt>(\s+<dd>(.*?)</dd>\s+)*?</dl>

但是这个匹配出的结果不太对，dd始终只匹配到了最后一个。这个表达式应该怎么修改呢？

正则

分享到：

------解决方案--------------------
分开匹配吧，dl 匹配一次，里面的dt和dd再匹配一次。
------解决方案--------------------
变通一下（待匹配的项数不定，形式语言基本无法实现）

preg_match_all('#<(d[dt])>\s*([^<]+)</\\1>#is', $s, $r);<br />
print_r($r);

Array
(
    [0] => Array
        (
            [0] => 

2013

            [1] => 

row1

            [2] => 

row2

            [3] => 

row3

            [4] => 

2014

            [5] => 

row1

            [6] => 

row2

        )

    [1] => Array
        (
            [0] => dt
            [1] => dd
            [2] => dd
            [3] => dd
