Hello hanson and alister,

Many thanks for your time to try to help. And thanks for your explanations, I have more clear some things.

hanson,

I was tried too, use double escaping but I had the semicolon in the same place either Smilie.

Alister,

May you explain me please, why that misplaces semicolon generates an empty if-statement.

When I need to put semicolon (when is mandatory and when is not)?

In this case, the semicolon was actually ruining the output.

Thanks for all the help.

PPI::Statement::Null(3) 				User Contributed Perl Documentation				   PPI::Statement::Null(3)

NAME
PPI::Statement::Null - A useless null statement SYNOPSIS
my $foo = 1; ; # <-- Null statement my $bar = 1; INHERITANCE
PPI::Statement::Null isa PPI::Statement isa PPI::Node isa PPI::Element DESCRIPTION
"PPI::Statement::Null" is a utility class designed to handle situations where PPI encounters a naked statement separator. Although strictly speaking, the semicolon is a statement separator and not a statement terminator, PPI considers a semicolon to be a statement terminator under most circumstances. In any case, the null statement has no purpose, and can be safely deleted with no ill effect. METHODS
"PPI::Statement::Null" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element. SUPPORT
See the support section in the main module. AUTHOR
