<p>「HTML 实体解析器」 是一种特殊的解析器，它将 HTML 代码作为输入，并用字符本身替换掉所有这些特殊的字符实体。</p>
|
|||
|
|
|
|||
|
|
<p>HTML 里这些特殊字符和它们对应的字符实体包括：</p>
|
|||
|
|
|
|||
|
|
<ul>
|
|||
|
|
<li><strong>双引号：</strong>字符实体为 <code>&quot;</code> ，对应的字符是 <code>"</code> 。</li>
|
|||
|
|
<li><strong>单引号：</strong>字符实体为 <code>&apos;</code> ，对应的字符是 <code>'</code> 。</li>
|
|||
|
|
<li><strong>与符号：</strong>字符实体为 <code>&amp;</code> ，对应对的字符是 <code>&</code> 。</li>
|
|||
|
|
<li><strong>大于号：</strong>字符实体为 <code>&gt;</code> ，对应的字符是 <code>></code> 。</li>
|
|||
|
|
<li><strong>小于号：</strong>字符实体为 <code>&lt;</code> ，对应的字符是 <code><</code> 。</li>
|
|||
|
|
<li><strong>斜线号：</strong>字符实体为 <code>&frasl;</code> ，对应的字符是 <code>/</code> 。</li>
|
|||
|
|
</ul>

<p>给你输入字符串 <code>text</code> ，请你实现一个 HTML 实体解析器，返回解析器解析后的结果。</p>
|
|||

|
|||
|
|
<strong>输出：</strong>"& is an HTML entity but &ambassador; is not."
|
|||

|
|||
|
|
<strong>输出：</strong>"x > y && x < y is always false"
|
|||
|
|
</pre>
|
|||
|
|
