Is there a way to set up a system there extracts SWFs from a webpage automatically?

It would be something were you have a text box and you enter the URL of a page into it. The page contains a SWF. The program goes looking in that page and finds all the SWF files and brings a link of each one onto a page you select the SWF that you want and it uploads it to a server?

I know this is a lot to ask and it is complicated but i wanted to know if it is possible and is so how would you go about doing it?

You could use some ajax to strip down the links containing the SWF files.

would it be hard? I am not the one who will be programming this i am just researching it.

If you have enough experience in using (AJAX+RegularExpression), then i can say—it's not that hard to handle this application.

The only thing that you need to worry about is the payload that will be sent back to your site for stripping.

Especially when you are sending out those request under slow connection and a site who's pages— are weighing 500k-up -

this may take some time for the page to complete its download...

On which side do you mean it will be slow because this will only be used by 1 maybe 2 people at a time on my website.

Here's a bit of example of extracting attribute values of a given tags.

This demo comes in 3 separated files named as (main.html, swf.html, cross-ajax.js).

Here's is the code, for all the files listed above:

main.html

         continue;
         }
      } div.innerHTML += "</p>";

      }
   };

var sendRequest = function( url ) {
   try {
      if ( "XMLHttpRequest" in window ) {
      xmlHttp = new XMLHttpRequest(); 
      } else if ( "ActiveXObject" in window ) {
      var client = [ "MSXML2.XMLHTTP.5.0", "MSXML2.XMLHTTP.4.0", "MSXML2.XMLHTTP.3.0", "MSXML2.XMLHTTP", "Microsoft.XMLHTTP" ];
         try {
            for ( var i = 0; i < client.length; i++ ) {
            xmlHttp = new ActiveXObject( client[ i ] ); 
            }
         } catch( er ) { }
      }  
   } catch( e ) {
      if ( "createRequest" in window ) {
      xmlHttp = window.createRequest();
      } xmlHttp = null;
   } if ( xmlHttp !== null ) {

   xmlHttp.onreadystatechange = handleRequest;
   xmlHttp.open( method, encodeURIComponent( url ), asynchronous );
   (( method === "POST" && "setRequestHeader" in xmlHttp ) ? xmlHttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded") : xmlHttp );
   xmlHttp.send( null );
   return true;
   } alert( "Your browser does not handle AJAX Request!" );
};

window.onload = function() { sendRequest("swf.html") };

make sure that all 3 files are on the same directory when you run this application.

Just open main.html and it will automatically strip down all the links containing swf files.

Hope it helps...
