PHP正則表達式幫助解析字符串

我有一個字符串，如下列：PHP正則表達式幫助解析字符串

Are you looking for a quality real estate company? 

<s>Josh's real estate firm specializes in helping people find homes from   
[city][State].</s> 

<s>Josh's real estate company is a boutique real estate firm serving clients 
locally.</s> 

In [city][state] I am sure you know how difficult it is 
to find a great home, but we work closely with you to give you exactly 
what you need

我想有這一段分成基礎上，<s> </s>標籤的數組，所以我有以下數組作爲結果：

[0] Are you looking for a quality real estate company? 
[1] Josh's real estate firm 
    specializes in helping people find homes from [city][State]. 
[2] Josh's real estate company is a boutique real estate firm serving clients 
    locally. 
[3] In [city][state] I am sure you know how difficult it is 
    to find a great home, but we work closely with you to give you exactly 
    what you need

這是我目前使用正則表達式：

$matches = array(); 
preg_match_all(":<s>(.*?)</s>:is", $string, $matches); 
$result = $matches[1]; 
print_r($result);

但這個只返回一個包含<s> </s>標籤之間的文本的數組，它忽略了在這些標籤之前和之後發現的文本。（在上面的例子中，將只返回數組元素1和2

任何想法

我可以用preg_split()而不是得到最接近？

$string = <<< STR 
Are you looking for a quality real estate company? <s>Josh's real estate firm 
specializes in helping people find homes from [city][State].</s> 
<s>Josh's real estate company is a boutique real estate firm serving clients 
locally.</s> In [city][state] I am sure you know how difficult it is 
to find a great home, but we work closely with you to give you exactly 
what you need 
STR; 

print_r(preg_split(':</?s>:is', $string));

，並得到這樣的輸出：

Array 
(
    [0] => Are you looking for a quality real estate company? 
    [1] => Josh's real estate firm 
specializes in helping people find homes from [city][State]. 
    [2] => 

    [3] => Josh's real estate company is a boutique real estate firm serving clients 
locally. 
    [4] => In [city][state] I am sure you know how difficult it is 
to find a great home, but we work closely with you to give you exactly 
what you need 
)

除了產生一個額外的數組元素（索引2）那裏的所述片段之間[city][State].</s>換行符和<s>Josh's real estate company。

雖然添加一些代碼來刪除空白匹配將是微不足道的，但我不確定是否需要這樣做。

額外的數組元素是好的，但它似乎在尋找的只是''，這意味着像'我的名字是鮑勃。 im 17。'和'我的名字是鮑勃。 ~~im 17~~'會被分成2個元素，它是否可以改變，所以第一個例子只保存在1個數組元素中？（我希望未打開的''不匹配）。 – 2010-06-30 06:07:46

此外，如果可以刪除空的數組元素，那麼我更喜歡它。 – 2010-06-30 06:24:10

我會用我的代碼撥弄一下，然後更新我的答案，如果我只能匹配正確打開和關閉的標籤，並刪除空的元素。 – BoltClock 2010-06-30 06:27:22

我建議你看看DOM http://php.net/manual/en/book.dom.php
