Question

I’m using Selenium for work and I have extract some data from “//ul”, unfortunately this data contains a newline, I tried to use chomp() function to remove this (because I need to write in a CSV’s file) but it’s not working, the portion of code is:

open (INFO, '>>file.csv') or die "$!";  
print INFO ("codice\;descrizione\;prezzo\;URLFoto\n");
my $sel = Test::WWW::Selenium->new( host => "localhost", 
                                    port => 4444, 
                                    browser => "*chrome", 
                                    browser_url => "http://www.example.com/page.htm" );
$sel->open_ok("/page.htm");
$sel->click_ok("//table[2]/tbody/tr/td/a/img");
$sel->wait_for_page_to_load_ok("30000");
my $descrizione = $sel->get_text("//ul");
my $prezzo = $sel->get_text("//p/font");
my $codice = $sel->get_text("//p/font/b");
my $img = $sel->get_attribute ("//p/img/\@src");
chomp ($descrizione);
print INFO ("$codice\;$descrizione\;$prezzo\;$img\n");
$sel->go_back_ok();

# Close file
close (INFO);

but the output is:

Answer 1

chomp removes the platform specific end-of-line character sequence from the end of a string or a set of strings.

In your case, you seem to have a single string with embedded newlines and/or carriage returns. Hence, you probably want to replace any sequence of possible line endings with something else, let’s say a single space character. In that case, you’d do:

$descrizione =~ s/[\r\n]+/ /g;
