Time for action – extracting a list of media links

There probably is a regular expression that would extract all of the "src" links from a page, but we're only interested in things that we know LiveCode is able to show or play. So this time we'll use a more devious way to extract just the links we can handle.

1. You may as well head over to the test stack!

2. Make a third button by duplicating one of the other two, and change the getLinks or getText part in the button script to call getMedia instead.

3. In the stack script, enter all of this:

   global gPageURL
   
   function getMedia pPageSource
      put ".jpg,.png,.gif,.jpeg,.mov,.mp4,m4v,.mp3" into tExtensions
      repeat with a = 1 to the number of items in tExtensions
         put item a of tExtensions into tExtension
         replace tExtension with tExtension & "*" & return in pPageSource
      end repeat
      repeat with a = the number of lines in pPageSource down to 1
         put line a of pPageSource into tLine
         if the last char of tLine is "*" then
    ...
