用于解析字符串的PHP正则表达式帮助

我有一个字符串，如下所示：

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

这是我当前使用的正则表达式：

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

$matches=array（）；
preg_match_all（“：（*？）：is“，$string，$matches）；
$result=$matches[1]；
打印（结果）；

但是这个函数只返回一个数组，其中包含在

标记之间找到的文本，它忽略了在这些标记之前和之后找到的文本。（在上面的示例中，它只返回数组元素1和2

---

有什么想法吗？

我能找到的最接近的方法是使用

preg\u split（）

：

$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));

除了生成一个额外的数组元素（索引

2

），其中片段

[城市][州]。

和

Josh的房地产公司

之间有一条新线

虽然添加一些代码来删除空白匹配项很简单，但我不确定您是否希望这样做。

我建议您研究DOM

---

额外的数组元素很好，但它似乎只查找

，这意味着类似

的东西我的名字是bob.im 17。

和

我的名字是bob.im 17

都将被拆分为2个元素，是否可以更改它，使第一个示例仅保留在1个数组元素中？（我希望未打开的

不匹配）。另外，如果可以删除空数组元素，那么我更喜欢它。我将稍微修改一下代码，然后更新我的答案，如果我能够匹配正确打开和关闭的标记，并删除空元素。

$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));

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
