Regexp can be pretty brutal for that kind of document parsing.
In direct answer to your question, I'm not sure you can negate a pattern,
only a list of
characters in brakets like so:
'!<#mytag>([^<]+)</#mytag>!'
any '<' character between the tags would break the pattern, but if you stick
to valid HTML
then you shouldn't find that character between tags anyway
allow matched tags to have attributes like so:
'!<#mytag[^>]*>([^<]+)</#mytag>!'
I suggest a look at the Smarty template engine. <smarty.php.net>
--or--
How about defining your own XML markup with two namespaces
<h1>Regular heading</h1>
<tpl:h1>Editable heading</tpl:h1>
-- stuff --
<tpl:p> ... editable paragraph ... </tpl:p>
A custom XML parser routine could do whatever you need when it comes across
your special tags.
I am about to embark on something similar myself
