I am parsing a webpage right now to make it 508 compliant.

Doesn't your parser have a means of locating IMG elements, and for each of them add an attributes if the attribute doesn't already exist? Looks like 3-4 lines of code.

Update: For XML::LibXML, it would be something similar to the following snippets. I expect something similar from HTML parsers. 

for my $ele ($doc->findnodes('//img')) {
   if (!defined($ele->getAttribute('alt'))) {
      $ele->setAttribute(alt => ...);
   }
}

or even 
for my $ele ($doc->findnodes('//img[count(@alt)==0]')) {
   $ele->setAttribute(alt => ...);
}
