The following examples are variations (not the actual because I could get in trouble here at work) of what I was able to do off the top of my head:

/^p\d{3}$/ // looks for a “p” followed by 3 digits
/^\d{6}(-\d{6})?$/ // looks for 6 digits with an optional dash then 6 more digits

Just thought I’d share in my own joy. Can you see the joy in those regex? Love it.

Note: I fixed the second example per Mitch’s bug find. Apparently my transcription from my whiteboard was not perfect. :-)

The code is as follows:

s/<a (.*?)HREF\s*=\s*"(?!(javascript|mailto|[#]))(.*?((FL(?{$w=250})|OV(?{$w=800})|TK(?{$w=350}))(\w|_)*?\.htm).*?)"(.*?)>
/<a href="http://www.orwd.com/blog/wp-admin/post.php#" mce_href="http://www.orwd.com/blog/wp-admin/post.php#" onClick="
w=window\.screen\.width-$w-12;
window\.open('$3','helpWin$i','top=0,left='+w+',width=$w,
height=650,top=no,status=no,toolbar=no,menubar=no,
location=no,scrollbars=yes,resizable=yes');">/gis;

I can happily blame Lynn Killam and my partner Fred Kush for this undertaking. I am very happy to tell you that it works beautifully.
