use Selenium::Remote::Driver;
 @webelements=$driver->find_elements("input","tag_name");
foreach $elemnt (@webelements){
    sleep(5);
    $string = $elemnt->get_attribute('src');
    print "The string is [$string] \n";
    if ( $string && $string =~ /disk25.gif/i){
         print "one lement found \n";
    $elemnt->submit();
    sleep(5);
        #$elemnt->click();
        my @handles = $driver->get_window_handles;
        print "handles in last loop @handles ".@handles;
        open (F1,'>C:\Users\u0156151\Desktop\final');
        open (FS,'>C:\Users\u0156151\Desktop\finalfile');
        #$F="Z$count";
        binmode FS;
         print FS $driver->get_page_source();
         print F1 $driver->get_page_source();
