在Perl中處理和解析文本通常使用正則表達式。下面是一些處理和解析文本的常用方法：
my $text = "This is a sample text";
if ($text =~ /sample/) {
print "Found 'sample' in the text\n";
}
my $text = "apple,orange,banana";
my @fruits = split(",", $text);
foreach my $fruit (@fruits) {
print "$fruit\n";
}
my $text = "Hello, World!";
$text =~ s/Hello/Hi/;
print $text; # 輸出 "Hi, World!"
my $text = " Perl is a powerful language ";
$text = trim($text);
print $text; # 輸出 "Perl is a powerful language"
use Text::ParseWords;
my $text = 'This is a "sample text" with "quotes"';
my @words = parse_line('"', 0, $text);
foreach my $word (@words) {
print "$word\n";
}
通過這些方法，可以方便地處理和解析文本數據，在Perl中進行文本處理變得更加簡單和高效。
