I got a string from which I want to extract some info. The string has a
format like this "$MyINFO $ALL %s %s$ $%s$%s$%s$|" ie "$MyINFO $ALL
[Sunet]smurf hmm$ $LAN(T3)$y**@mail.no$85899345920$|" for doing this I use
the The GNU C Library regular expression library.
My matchstring looks like this "$MyINFO $ALL \\(.*\\) \\(.*\\)$
$\\(.*\\)$\\(.*\\)$\\(.*\\)$|" it works fine for the 4 strings but it's
unable to match the last one which it seems to think starts from the first
space and ends at '|'. I'm a little unsure how the escapes characters works
but I think I got them right, the manual doesnt say much about them (
http://www.gnu.org/manual/glibc-2.2....lar%20Expressi
ons ).
thx for your help

outputs:
