拆分时动态重建html标签

Question

当出现特定变量时，我需要将html分成两部分。

以下是一个例子：

<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>

最后我想要的是什么：

<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>

以下是我的想法（告诉我是否有更好的方法）：

1. 拆分我的变量
2. 通过正则表达式获取所有标签？ （我只知道正则表达式告诉我真或假）
3. 将所有标签放在堆叠上？
4. 循环两次（数组拆分1和数组拆分2）

编辑示例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>

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>

变通

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

众所周知，您应该使用 html解析器而不是正则表达式。

无论如何，你可以使用一个简单的字符串replaceAll来做你想要的。如果你想使用正则表达式，你可以使用这样的东西：

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>
