拆分時動態重建html標記

Question

當出現特定變量時，我需要將我的html分成兩部分。

下面是一個例子：

<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> 

我想在最後什麼：

<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> 

這是我想（告訴我，如果有更好的方法）：

1. 在我的變量上分割
2. 通過正則表達式獲取所有標記？ （我只是知道正則表達式來告訴我是真是假）
3. 把所有的標籤都放在堆棧上？
4. 循環兩次（陣列分割1和陣列分開2）

EDIT實施例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> 

可變

<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> 

爲例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

這是衆所周知的是，你應該使用HTML解析器，而不是一個正則表達式。

無論如何，你可以使用一個簡單的字符串replaceAll來做你想做的。如果你想使用正則表達式你可以使用這樣的事情：

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);
