Thanks Ravinder,

I generally use various online REGEX checkers when when I am writing REGEX expressions, mostly REGEX for PHP code.

This is the first one I have seen that has the "visualization" done like this, thanks for sharing.

The REGEX checkers I like the best have always been the ones where we can cut-and-paste our text into the checker and then see
the resulting matches so we can easily test the input versus the output when debugging.

Next time I need a REGEX I will also try this visualization tool.

Thanks for sharing.
