Regexp help

[mike]

Hi,

I have the following line that I want to use a regexp to match:

I have tried the following pattern.

String pattern = "#define\\s[A-Z_]+\\s\\(\\"[A-Z_]+\\"\\)";

This is the input line that I want to match:

#define MY_NAME_INTERFACE ("GROUP_INTERFACE_04")

MY_NAME_INTERFACE - can contain any caps and underscore.
GROUP_INTERFACE_04 - can contain any caps and underscore as well as
digits at the end.

br,

//mike

You forgot the digits in your pattern.

Use just "\"" to put a quote in a string, and do not try to protect it
from interpretation by the regexp engine at all. It is not special.

Thanks!

I missed about the " character.

String pattern = "#define\\s[A-Z_]+\\s\\(\\"[A-Z_]+\\"\\)"; [...]
#define MY_NAME_INTERFACE ("GROUP_INTERFACE_04")

in general there can be as much whitespaces as you like, so
\\s should better be \\s+
