Perl: pattern matching in a conditional

In this snippet of code:
printf("<email preferred=\"true\">\n") if ( $Campi[0] ne "");

Open in new window

I should add another condition:
if $Campi[0]  does not begin with ">>"
I've tried something like
printf("<email preferred=\"true\">\n") if (( $Campi[0] ne "") OR ( $Campi[0] !~ m/^>>/=true));

Open in new window

but without luck
Thanks,
Fabiano

Shouldn't OR be AND?
printf("<email preferred=\"true\">\n") if (( $Campi[0] ne "") and ( $Campi[0] !~ m/^>>/));

Hi, Norie
no: I want to override the print of
<email preferred=\"true\">\n

Open in new window

in both cases:
  • a) if $Campi[0] is null
  • b) if $Campi[0] begins with ">>"
Thanks

Try using lower case || or lower case or.

tested:
printf("<email preferred=\"true\">\n") if (( $Campi[0] ne "") or ( $Campi[0] !~ m/^>>/=true));

Open in new window

but I obtain the following error:

Can't modify not in scalar assignment at personale.pl line 114, near "true)"
Execution of personale.pl aborted due to compilation errors.

Open in new window

Sorry, my fault.

You also need to remove '=true'.

printf("<email preferred=\"true\">\n") if (( $Campi[0] ne "") or ( $Campi[0] !~ m/^>>/));

Hi Norie,

> "Try using lower case || or lower case or."
What does "lower case ||" mean?  I didn't know "||" had case.
