Re: How to clean an array of strings after a split

You could also search the pieces of interest with a single regex, and fill the array with sufficiently many empty strings like this:

my ($var1, $var2, $var3, $var4, $var5) = ( $str =~ /(?:^|\|)\s*(.*?)\s
+*(?=$|\|)/g, ("")x5 );

Thanks, but please explain what this does: `(?:^\|\\|)` and this: `(?=$\|\\|)`	[reply] [d/l] [select]

`(?: non-capturing parentheses ^ start of string \| or \\| pipe character )` [download] `(?= look-ahead, not part of match $ end of string \| or \\| pipe character )` [download] So I am looking for something between the start of string or a pipe and a pipe or the end of the string, ignoring whitespace, matching non-greedily. In order to make it work, I need to use each pipe twice, once for the string before the pipe, and then for the string following it. Thus the look-ahead assertion. HTH.	[reply] [d/l] [select]
