Html escape转义问题

https://www.freeformatter.com/html-escape.html

Escapes or unescapes an HTML file removing traces of offending characters that could be wrongfully interpreted as markup.

The following characters are reserved in HTML and must be replaced with their corresponding HTML entities:

• " is replaced with "
• & is replaced with &
• < is replaced with &lt;
• > is replaced with &gt;

 

<123><script>
&amp;
&quot;
&lt;
&gt;

经过转义之后变为

&lt;123&gt;&lt;script&gt;
&amp;amp;
&amp;quot;
&amp;lt;
&amp;gt;
