CDATASection

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The CDATASection interface represents a CDATA section that can be used within XML to include extended portions of unescaped text. When inside a CDATA section, the symbols < and & don't need escaping as they normally do.

In XML, a CDATA section looks like:

xml
<![CDATA[ … ]]>

For example:

xml
<foo>
  Here is a CDATA section: <![CDATA[ < > & ]]> with all kinds of unescaped text.
</foo>

The only sequence which is not allowed within a CDATA section is the closing sequence of a CDATA section itself, ]]>.

Note: CDATA sections should not be used within HTML. They are considered comments and are not displayed.
