Split file content	Can't Post

Hi to all,
I'm new here.

I've a little problem with a perl script.
I have a file with many information. with ":" in it.
For example:
word1Line1:word2Line1:word3Line1
word1Line2:word2Line2
....

I should have an output file with Word splitted each for new line:
word1Line1
word2Line1
word3Line1
<separator>
word1Line2
word2Line2

I try to split it with following loop, without any output:

Code

open (myfile, 'test.log'); 
while (<myfile>){ 
 $SplitVar = split (':', <myfile>); 
} 
print $SplitVar; 
close (myfile);

supposing you have this line in your file

Code

$line = "word1Line1:word2Line1:word3Line1  
word1Line2:word2Line2 "; 
@txt = split (/:/, $line);

then you need a for loop to display it

Code

for ($i = 0; $i < @txt; $i++) { 
	print "$txt[$i]\n"; 
	}

Many thanks Jurafsky,
how should I change split command to have following syntax, with ":" at the end?

word1line1:
word2line1:
.....

Thanks to you.

You mean that you want to keep the : at the end of your line?

Well, split on ':' will remove it, so either you add it back after the split, or you use another syntax such as:

Code

$line = " word1line1: word1line2: word1line3:"; 
$line =~ s/:/:\n/g; 
print $line;

which will print:

Code

word1line1: 
word1line2: 
word1line3:
