I found nothing of adequate to my needs, so I started working on it.

The main idea is of a module that uses OpenOffice::OODoc::Document to manage the odt file, XML::Twig to manipulate the content, a HoAoH structured data block, and a minimal scripting language to describe the actions to be taken by the parser.

I just wrote a draft and uploaded it in psini's scratchpad describing the language to implement; if you (or anyone) are interested in this project, any suggestion or critic is welcome: I thought about it in view of my specific needs at present, so I may have forgot some possible use; maybe the structure of the language is too simple or too complex and, last but not least, I know that my English is awful, so any grammar or stylistic correction is welcome too.
