There is none! HTML is a type-2 language and thus not parsable with a regular expression (type-3).
See this wiki article in case of doubt.
Lots of people use regex for parsing/editing HTML. This works quite well in simple cases but is utterly error prone.
This being said: You should have fairly reliable results with this regex:
This requires “.” to also match line breaks. If it doesn’t, then use this:
Again: This is error prone, don’t do it.
What you should use is an XML parser such as
NSXMLParser.
