in reply to Re: LWP::UserAgent & match
in thread LWP::UserAgent & match

Thanks hippo. I did make the change but no luck in match. BTW, the $string does contain the matcheded string $todaysQuoteStr. My revised code 
use strict;
use warnings;
use LWP::UserAgent;
use feature 'say';
my ($position,$price);
my $todaysQuoteStr = 'data-reactid="49"><span class="Trsdu(0.3s) Fw(b)
+ Fz(36px) Mb(-4px) D(ib)" data-reactid="50">';
$todaysQuoteStr = quotemeta($todaysQuoteStr);

my $url = 'https://finance.yahoo.com/quote/AAPL?p=AAPL&.tsrc=fin-srch'
+;

my $ua = LWP::UserAgent->new();
my $req = HTTP::Request->new(GET => $url);
$ua->agent('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.
+36 (KHTML, like Gecko) Chrome/80.0.3987.163 Safari/537.36');

my $response = $ua->request($req);
my $string = $response->decoded_content;
#say "string = $string";
say "\t\t\t=>searching for todays quote pattern [$todaysQuoteStr]";   
+ 

$position = 0;

if ($string =~ m/$todaysQuoteStr/) {
    my $quoteStr = substr $string, $position, 20;
    say "quoteStr = $quoteStr";
    my @quotes   = split(/<\/span>/,$quoteStr);
    $price = $quotes[0];
    say "\t\t\t[price = $price]"; 
} else {
    say "\t\t\t pattern not found";
}

   $counter++;
   $position = pos($string);
   if ($counter == 1) {last;} # 
}
if (!(defined($position))) { $position = ''; }
if ($position eq '') {
    say "\t\t\t\t<<pattern not found!>> ";
} else {
    my $quoteStr = substr $string, $position, 20;
    say "quoteStr = $quoteStr";
    my $endStr = '</span>';
