Re: RegEx: How to ignore the number of whitespaces?

Hi,
thanks for your response!

Hope this is something like what you meant:
"Users of my programme input sequences of arbitrary Unicode characters
(from now on, referred to as "patterns"). These patterns are supposed
to match other given sequences of Unicode characters (from now on,
referred to as "strings").

Certain subsequences of a pattern may be marked as optional. These may
be found in the string, but need not.
Certain subsequences of a pattern may be marked as a set of
alternatives. Exactly one of them must be found in the string, neither
more nor less.
A pattern will never require more than one space character without any
other characters in between to be found in a string.
A pattern will accept any number of space characters (greater than
zero) without any other characters in between in the string at a
position where a space character is expected.
A pattern will ignore any space characters at the beginning and at the
end of a string.
A pattern will never require any space characters at the beginning and
at the end of a string."

I'm looking for the easiest way to quickly convert the pattern into a
standard regular expression.

Thanks in advance,
Florian
