[TextMate] multiple folding structures for latex

[profprof at mac.com]

I am trying to improve the syntaxe for the Latex bundle. However, I am not familiar with plist. 

In addition to structures of the type 

\begin{..}

\end{...}

I would like to add a folding of the \section, \chapter, \subsection structure. 

For this, I thought of adding in a snipped a line at the end of these structures which would be considered as a comment by Latex:

\section{This is a section}


%\end-section{This is a section}

\section{A new section}
....

I have tried to modified the current Latex.plist to :

         <key>foldingStartMarker</key>
           <string>(\\begin\{.*\}|\\(((sub)*section)|(chapter)|(paragraph)|(part))(\*?)\{.*\})</string>
           <key>foldingStopMarker</key>
           <string>(\\end\{.*\}|%\\end-(((sub)*section)|(chapter)|(paragraph)|(part))(\*?)\{.*\})</string>

However, this does not work very well as if there is any substructure in a \section of the type (\end{equation}, for example), the folding occurs from \section to \end{equation}.

Anybody could tell me how to correct that??

I thank you in advance!
