you're missing a point ...

remember: you asked sscanf to match a pattern, and it will ;

what sscanf will not do, is to search (crawl) for a pattern, for this is the purpose of strstr ... see below:

Code:

#include <stdio.h>
#include <string.h>
int main(void) {
	char A[5000] = "";
	float B = 0;
	char * begin;

	strcat(A, "		hello world! WORD' name='5.3498' hello world!            ");
	begin = strstr (A, "WORD'") ;
	sscanf(begin, "WORD' name='%f", &B); // how can I match all chars before WORD and after the float ?

	printf("%f\n", B);

	return 0;
}

- strstr will actually find the beginning of the pattern to match, and sscanf will do what it does best: just scan ...

ok ?

good luck, and success !
