拆分时动态重建html标记

Question

当出现特定变量时，我需要将我的html分成两部分。

下面是一个例子：

<h1>I can have any kind of text here</h1> 
<p>&nbsp;</p> 
<p><em><strong>When I see this variable :)</strong> I want to rebuild my html.</em></p> 

我想在最后什么：

<h1>I can have any kind of text here</h1> 
<p>&nbsp;</p> 
<p><em><strong>When I see this</strong></em></p> 

<p><em><strong> :)</strong> I want to rebuild my html.</em></p> 

这是我想（告诉我，如果有更好的方法）：

1. 在我的变量上分割
2. 通过正则表达式获取所有标记？ （我只是知道正则表达式来告诉我是真是假）
3. 把所有的标签都放在堆栈上？
4. 循环两次（阵列分割1和阵列分开2）

EDIT实施例2：

<ol> 
<li> 
<h2>I can have any kind of text here 1</h2> 
</li> 
<li> 
<h2><strong>I can have any kind of text here 2 variable</strong></h2> 
</li> 
<li> 
<h2><strong>I can have any kind of text here 3</strong></h2> 
</li> 
<li> 
<h2>I can have any kind of text here 4</h2> 
</li> 
<li><em><strong>When I see this</strong></em></li> 
</ol> 
<p>&nbsp;</p> 

...

<ol> 
<li> 
<h2>I can have any kind of text here 1</h2> 
</li> 
<li> 
<h2><strong>I can have any kind of text here 2 variable </strong></h2> 
</li> 
</ol> 

可变

<ol> 
<li> 
<h2><strong>I can have any kind of text here 3</strong></h2> 
</li> 
<li> 
<h2>I can have any kind of text here 4</h2> 
</li> 
<li><em><strong>When I see this</strong></em></li> 
</ol> 
<p>&nbsp;</p> 

为例3：

<p><a href="test">I can have any kind of text of varaible here even clickable.</a></p> 

...

<p><a href="test">I can have any kind of text of</a></p> 

varaible

<p><a href="test">here even clickable.</a></p> 

Answer 1

这是众所周知的是，你应该使用HTML解析器，而不是一个正则表达式。

无论如何，你可以使用一个简单的字符串replaceAll来做你想做的。如果你想使用正则表达式你可以使用这样的事情：

String str = "<h1>I can have any kind of text here</h1>\n<p>&nbsp;</p>\n<p><em><strong>When I see this variable :)</strong> I want to rebuild my html.</em></p>\n"; 
str = str.replaceAll("variable", "</strong></em></p>\n<p><em><strong>"); 
System.out.println(str);

输出

<h1>I can have any kind of text here</h1> 
<p>&nbsp;</p> 
<p><em><strong>When I see this </strong></em></p> 
<p><em><strong> :)</strong> I want to rebuild my html.</em></p>
