Answer 1

I used this regx in C#, and it works. Thanks for all your answers.

<([^<]*)>|([^<]*)

Answer 2

This has already been answered literally dozens of times, but it bears repeating: regular expressions can only parse regular languages, that's why they are called regular expressions. HTML is not a regular language (as probably every college student in the last decade has proved at least once), and therefore cannot be parsed by regular expressions.

Answer 3

you might want to simply use string functions. make < and > as your indicator for parsing.

Answer 4

Regular expressions are a very poor way to parse HTML. If you can guarantee that your input will be well-formed XML (i.e. XHTML), you can use XmlReader to read the elements and then print them out however you like.

Answer 5

You might want to try the Html Agility Pack, http://www.codeplex.com/htmlagilitypack. It even handles malformed HTML.
