Please 开发者_StackOverflow社区tell me when I add in the xml while writing <![CDATA[ content ]]> then when I view the source in Mozilla Firefox then it shows <![CDATA[ content ]]> and when I parse this xml then is it escape or it comes? Please tell me! I want to parse this xml in objective C?

The purpose of CDATA is to mark things that shouldn't be parsed. Anything you put within <![CDATA[...]]> will not be parsed.
