Question

i have the following regex:

private string tokenRegEx = @"\[%RC:(\w+)%\].*?";

which is when i pass in the string below it finds it:

[%RC:TEST%]

However the following returns false

[%RC:TEST ITEM%]

how can i modify the regex to allow for spaces as well as whole words?

Answer 1

You need to change the \w pattern (which matches alphanum plus underscore only) to something more liberal. For example this would also allow whitespace:

private string tokenRegEx = @"\[%RC:((\w|\s)+)%\].*?"; 

Of course the “correct” solution would need to take into account exactly what you consider acceptable input, which is kind of open to discussion at this point.
