PHP正则表达式帮助解析字符串

我有一个字符串，如下列：PHP正则表达式帮助解析字符串

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

我想有这一段分成基础上，<s> </s>标签的数组，所以我有以下数组作为结果：

[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

这是我目前使用正则表达式：

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

但这个只返回一个包含<s> </s>标签之间的文本的数组，它忽略了在这些标签之前和之后发现的文本。（在上面的例子中，将只返回数组元素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));

，并得到这样的输出：

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 
)

除了产生一个额外的数组元素（索引2）那里的所述片段之间[city][State].</s>换行符和<s>Josh's real estate company。

虽然添加一些代码来删除空白匹配将是微不足道的，但我不确定是否需要这样做。

额外的数组元素是好的，但它似乎在寻找的只是''，这意味着像'我的名字是鲍勃。 im 17。'和'我的名字是鲍勃。 ~~im 17~~'会被分成2个元素，它是否可以改变，所以第一个例子只保存在1个数组元素中？（我希望未打开的''不匹配）。 – 2010-06-30 06:07:46

此外，如果可以删除空的数组元素，那么我更喜欢它。 – 2010-06-30 06:24:10

我会用我的代码拨弄一下，然后更新我的答案，如果我只能匹配正确打开和关闭的标签，并删除空的元素。 – BoltClock 2010-06-30 06:27:22

我建议你看看DOM http://php.net/manual/en/book.dom.php
