Question

I’m looking for a regex to remove all trailing asterisks and all asterisks inside a word.

*He*llo* -> Hello* <br>
Thi*s *is* *a* t*est* -> This is* a* test*

Ending asterisks should be accepted.

I’m not really experienced with regexes. I know I can write a simple program that loops through each word of a string and remove trailing and ‘in-word’ asterisks –
but I wonder whether my problem can be solved using a regex, or not.

Hope that you can help me.
Thank you in advance.

Best regards,
Ioannis K.

You need to use look ahead.

Take a look here :
http://www.regular-expressions.info/lookaround.html

This is something like : \*(?!( |$))

This regex says : delete all * which are not followed by a space or the end of the line.
