What does <![CDATA[]]> in XML mean?
- by mystify
I often find this strange CDATA tag in XML files:
<![CDATA[]]>
I have observed that this CDATA tag always comes at the beginning, and then followed by some stuff.
But sometimes it is used, sometimes it is not. I assume it is to mark that some "data" will be inserted after that. But what kind of "data"? Isn't anything I write in XML tags some sort of "data"?
