I'm a big fan of simplifying regex. I think a simpler regex would be

\[shortcodename id=\"12\"\](.*)\[\/shortcodename\]

If the id changes:
\[shortcodename id=\"[0-9]+\"\](.*)\[\/shortcodename\]
or
\[shortcodename id=\"[^"]+\"\](.*)\[\/shortcodename\]


How you use these is up to you.  My 2 cents: If this is a one-off, I'd
consider using mysqldump and vi or sed to modify the dbdump rather than
compiling and installing installing UDFs. Something like this:

mysqldump -flags your_database | sed s/\[shortcodename[
]?.*\](.*)\[\/shotcodename\]/\1/g  >new_sql

Here's a test with some escaped characters for sed and shell
:
mickey$ echo '[shortcodename id="foo"]bar[/shortcodename]' | sed
"s/\[shortcodename[ ]*[^]]*\]\([^[]*\)\[\/shortcodename\]/\1/g"
bar
mickey$

Egad I haven't seen a regex discussion in years.
