推荐答案

来自维基百科

CDATA 部分以下列顺序开始:

A CDATA section starts with the following sequence:

<![CDATA[

并以第一次出现的序列结束:

and ends with the first occurrence of the sequence:

]]>

这两个序列之间包含的所有字符都被解释为字符，而不是标记或实体引用.例如，在这样的一行中:

All characters enclosed between these two sequences are interpreted as characters, not markup or entity references. For example, in a line like this:

<sender>John Smith</sender>

开始和结束sender"标签被解释为标记.但是，如果这样写:

the opening and closing "sender" tags are interpreted as markup. However, if written like this:

<![CDATA[<sender>John Smith</sender>]]>

然后代码被解释为就像它是这样写的一样:

then the code is interpreted the same as if it had been written like this:

<sender>John Smith</sender>
