Oh, and assertatation are lookups like this one: (?!R_) (?=[^_])
But so far they are all wrong.

Question
Regular expression help
Hi,
I have the following lines.
-abcd "x" NR_name NR_abdcd NR_carw R_what R_noway R_word - line 1
-abcd R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
-abcd opt1 R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
I know the pattern for NR_(expression) or R_(expression) and for each given line
I need to store the first set of words and the word with the expression into variables
So for line 1 if my pattern is "what" I want to store -abcd, "x" and R_what into 3 variables
and for line 2 if my pattern is "carw" I want to store -abcd and NR_carw into 2 variables
for line 3 if my pattern is "abdcd" then i want to store -abcd,opt1 and NR_abdcd into 3 variables
so on,
Basically I want to store all the words till R_* or NR_* and finally store the
(R_* or NR_*) whichever matches my pattern.
This is what I am doing and for some reason it is not working any suggestions on how to do it
if ($Data[$k]=~/^(-\S+)\s+(\S
{
print "Debug4 \n";
$xyz1 = $1;
$xyz2 = $2;
$xyz3 = $3;
Finally I also want to be able to figure out if any of my words have double quotes and
store the values between quotes.
so for line 1 -abcd is followed by "x" which is a non (R_* or a NR_*) word and since it
has double quotes I want to save only x to an variable.
for line 2 -abcd is not followed by any non (R_* or a NR_*) so i do nothing
for line 3 -abcd is followed by opt1 which does have quotes so I want to save opt1 to an
variable.
x
Thnak you

How about this work around:
$lines = <<EOL;
-abcd "x" NR_name NR_abdcd NR_carw R_what R_noway R_word - line 1
-abcd R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
-abcd opt1 R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
EOL
$pattern = "carw";
@Data = split("\n", $lines);
for($k=0;$k<@Data;$k++){
#print $Data[$k]."\n";
if ($Data[$k]=~/^(-\w+)\W+(\w
$xyz1 = $1;
$xyz2 = $2;
$xyz3 = $3;
$_ = $xyz2;
$xyz2 = "" if (/_/);
print "1:$xyz1 2:$xyz2 3:$xyz3\n";
}
}
And if you like to have value three shifted if value2 is empty, then try this:
$lines = <<EOL;
-abcd "x" NR_name NR_abdcd NR_carw R_what R_noway R_word - line 1
-abcd R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
-abcd opt1 R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
EOL
$pattern = "carw";
@Data = split("\n", $lines);
for($k=0;$k<@Data;$k++){
#print $Data[$k]."\n";
if ($Data[$k]=~/^(-\w+)\W+(\w
$xyz1 = $1;
$xyz2 = $2;
$xyz3 = $3;
if($xyz2 =~ /_/){
$xyz2 = $xyz3;
$xyz3 = "";
}
print "1:$xyz1 2:$xyz2 3:$xyz3\n";
}
}
Nice expression :)
$lines = <<EOL;
-abcd "x" NR_name NR_abdcd NR_carw R_what R_noway R_word - line 1
-abcd R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
-abcd opt1 R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
EOL
$pattern = "carw";
@Data = split("\n", $lines);
for($k=0;$k<@Data;$k++){
@xyz = map{/^"?(\S*?)"?$/}(split/
foreach (@xyz){
print "$_\t";
}
print "\n";
}
Or into vars like this:
$lines = <<EOL;
-abcd "x" NR_name NR_abdcd NR_carw R_what R_noway R_word - line 1
-abcd R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
-abcd opt1 R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
EOL
$pattern = "carw";
@Data = split("\n", $lines);
for($k=0;$k<@Data;$k++){
@xyz = map{/^"?(\S*?)"?$/}(split/
($xyz1,$xyz2,$xyz3) = @xyz;
print "$xyz1\t$xyz2\t$xyz3\n";
}

I am working on the assertation that second word is not a R_ option, but so far I did not succeed.
My actual state is this:
$lines = <<EOL;
-abcd "x" NR_name NR_abdcd NR_carw R_what R_noway R_word - line 1
-abcd R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
-abcd opt1 R_name NR_abdcd NR_carw R_what R_noway R_word - line 2
EOL
$pattern = "carw";
@Data = split("\n", $lines);
for($k=0;$k<@Data;$k++){
#print $Data[$k]."\n";
if ($Data[$k]=~/^(-\w+)\W+(\w
$xyz1 = $1;
$xyz2 = $2;
$xyz3 = $3;
print "1:$xyz1 2:$xyz2 3:$xyz3\n";
}
}
