Esteemed Monks:

I'm having a difficulty with a snippet of code. The larger context requires that I replace one image link embedded deep inside each of over 100 HTML recipe files. The current link in each document is a relative link and each image has a different, unknown ID number as such:
<img src='../../images/dbimage.asp?ID=758'>

The replacement string is constructed of a title gleaned from the title of the recipe and munged into a proper HTML format. I've built code that gets the title and gets to the image tag. I just can't seem to get the regex replacement to work correctly. The relevent snippet is this:

while ( $token=$p->get_token() )
{
if ($token->is_start_tag('img') )
{
my $src = $token->return_attr->{src};
 print "SRC IS $src\n";  #For Debugging
 $src =~ s/$src/$newsrc/;
 print "SRC NOW: $src\n"; #For Debugging
 $token->set_attr('src', $src);
}

There are two other image references after the one I'm interested in and the looping picks through all of them. (At this point, that's not a problem.) When I run the script on a file, my printed debugging output is this:

got filetitle: ApplePecanBreadStuffing
SRC IS ../../images/dbimage.asp?ID=751
SRC NOW: ../../images/dbimage.asp?ID=751
SRC IS ../../images/spacer.gif
SRC NOW: 'ApplePecanBreadStuffing.jpg'
SRC IS ../../images/spacer.gif
SRC NOW: 'ApplePecanBreadStuffing.jpg'

Why is the first tag missed in the replacement step and the following two work correctly? I keep looking at it and I suspect it's something obvious in the structure of the code, but I am out of ideas. Help?
