Extended Knowledge

XML defines 5 predefined entity references: &lt; (<), &gt; (>), &amp; (&), &quot; ("), &apos; ('). & must be escaped first, otherwise existing entity references will be broken. CDATA sections (<![CDATA[...]]>) don't need escaping. HTML also supports numeric entity references (&#60;) and named entities (&nbsp; etc.). In XHTML, &apos; may not be supported by all browsers; &#39; is recommended as an alternative.
