Hi all
Think I have a better unstanding of the use of () for my regex search,
but this morning I have a new set of problems, whereby I need to perform
a search and replace and then pass on to the new variable.
My current code is as so, and works:
$_ =~ s/(^\w+\.dat\|)//; my $lineExtract = $_;
But I would like to have it a one liner.
I tried:
my ($lineExtract) = ($_ =~ s/(^\w+\.dat\|)//);
and
$lineExtract = ($_ =~ s/(^\w+\.dat\|)//);
($lineExtract) = /^\w+\.dat\|(.+)$/o;
s/(^\w+\.dat\|)//o says you want to remove all the \w+.dat| stuff
from the string in $_ and store it in $1;
If you want $lineExtract to be what is left after it's striped of the
\w+\.dat\| then you only need to use the line above.
If you want $lineExtract to contain the material that has been removed
then you want:
$lineExtract = /(^\w+\.dat\|)/o
If you want both... could you do this:
($lineExtract, $_) = /(^\w+\.dat\|)(.+)$/o;
I think it would work, but you'll want to test it.
(I like to add the regex option 'o' at the end to improve performance.)
