The defined Grammer here is
{
xyz1 abc1; /*Comments*/
xyz2 abc2;
xyz3 abc3[req];
xyz4 abc4[req]; /*Comments*/
};
Here, i have defined different possibility of occurences of the structure
elements. If i could get a regex for extracting xyz1, xyz2, xyz3, xyz4 and
abc1, abc2, abc3[req], abc4[req] would be helpful. Here, the comments are of
no use, i just need to ignore them.
Correct me if I'm wrong, but from your example, it looks like all the
"Dtata Types" are uppercase alphanumerics and underscores, and all the
"variable names" are preceded with at least one space.
I would start with something like the (fragile) following:
my @lines = split /\n/, $string;
while (@lines) {
$_ = shift @lines;
next if /^{/ or /^}/;
my ($type, $name) = /([A-Z_]+)\s*(\S+)/;
if ($name =~ /\[\S+\]/) {
do something with the extra data, or not
}
}
