Regular Expressions
Code:
#!/usr/bin/perl
$word = "one last challenge";
if ( $word =~ /^(\w+).*\s(\w+)$/ )
{
print "$1";
print "\n";
print "$2";
}
The output shows that "$1" is with result one and "$2" is with result challenge. I am confused about how this pattern match expression works step by step. I request u guys` explanation. Thank u very much. Last edited by pludi; 11-02-2009 at 09:57 AM.. Reason: code tags, please... |
