    You're not using quotemeta :)

     my( $lid ) = m{\Q<div class='PlayVideo'></div>\E(.*?)<div class='RadioButtonClipStyle'>}s;

      it is fetching the whole img tag
      i need the value of src attribute only

        No it isn't, there is no image tags in the data you posted

        If you can't keep your posting straight, take a break

        strike it out and update with an explanation why, rather than removing the title and post conents.

    In a much as I will not recommend using regex to parse HTML doc., however, for this you could use Look-Around Assertions like so:

    use warnings; use strict; my $str = "<div class='PlayVideo'></div> A8A <div class='RadioButtonClipStyle'>"; if ( $str =~ m#(?<=</div>)(.+?)(?=<div.+?>)#s ) { print $1; ## prints A8A }

    If you tell me, I'll forget.
    If you show me, I'll remember.
    if you involve me, I'll understand.

      your solution is correct but the file i am parsing contains many div tag
      can you please provide the more specific solution

        Since you're having so many problems achieving this with a regex, have you considered taking the previous advice of using a HTML Parser?

    Do not use regular expressions to parse HTML. Use a proper tool. For example, using XML::XSH2, you can load the whole file and extract the string easily:
    open :F html 1011977.html ; echo //div[@class="PlayVideo"]/following-sibling::text() ;
