Re: Etxraction of numbers in an array

t-rex, you will have to try a bit harder with your posts. With 47 posts, you've been around long enough that by now you should have at least mastered some of the syntax and terminology.

I have the following string: A1=<m,n>:<p,q>:<s,t>...go on

Is all of that stuff in code brackets the "string"?
Or, is the A1= part meant to indicate that the rest is assigned to a variable called "A1"?
If so, where are the quotes ('' or "") around the "string"?
Where is the sigil($) on the variable name?
Is the "..,go on" also part of the string?
Or is that meant to indicate that the :<n,m> bit can be repeated more times?
If so, don't you mean "so on"?
And wouldn't it be clearer if you put that bit outside of the code brackets!?

I have to extract values m,n,p,q,s,t from the above array.

Why has the "string" suddenly become an "array"?
Are m,n, etc. just single alphabetical characters? Or perhaps single digit numbers? Or multi-digit numbers?

How do i do it

After 6 months here you haven't achieved any enlightenment as to where to start?

I'd do it this way: `#! perl -sw use strict; my $string = "<1,2>:<5,7>:<3,0>"; my @x = $string =~ m[<(\d+),(\d+)>]g; print "Extraction = @x\n"; print "1st element = $x[0]"; __END__ c:\test>junk Extraction = 1 2 5 7 3 0 1st element = 1` [download] With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
