The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Regular expression help

Asked by vtumati in Perl Programming Language

Tags: xyz1

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*)\.+(\S+_[$pattern])\.+/)
{
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
