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!

Create a multi-dimensional array from a repeating list of items

Tags: Perl
I have an array that looks like this:

'Tablespace Name  =  ABC
Data Size = 123
Log Size = 456
Free Space = 111
Tablespace Name = DEF
Data Size = 456
Log size 123
Used Space = 333
Free Space = 222
Tablespace Name = XYZ
Data Size = 789
Log size 123
Free Space = 444

What I need is a multidimensional array that looks like this:

['ABC',123,456,,111]
['DEF',456,123,333,222]
['XYZ',789,123,,444]

Please notice that the 2nd "group" of entries has 1 one item that the others.  

What is the easiest way to accomplish this task?

If your original array is @oldarray:

1:
2:
3:
4:
5:
6:
7:
8:
9:
10:
11:
my %tmp;
my @array;
foreach (@oldarray) {
	next unless /^(.*?)\s*=\s*(.*?)\s*$/;
	$tmp{lc($1)} = $2;
	if($1 =~ /Free\s+Space/i) {
		push @array, [$tmp{'tablespace name'}, $tmp{'data size'}, $tmp{'log size'}, $tmp{'used space'}, $tmp{'free space'}];
		%tmp = ();
	}
	
}

What is the source of your original array?  Can you skip this step and put your data directly into a multidimensional array?
 
03.04.2008 at 03:50AM PST, ID: 21040042
The source for my original array is a 'db2 list directory' command.  From inside my perl script I use backticks to execute the command and all the results are returned into a one dimensional array.

Adam314,

Your code brought me close to what I needed.  Thanks...
