[xwiki-devs] Exclude a piece of content from pdf result document

Hi, I need to compile all pages (from parent to children) to one pdf document. Pages may contain a piece of data not to be included to the final document. This piece of data can be bound with [Exclude] ... [/Exclude] tags, or smth like this. Currently I see the only way to do it with parsing the each page 'String' content before including it to the output document and get rid of these pieces. But currently I experience some issues with this approach and it seems not clean. Is there another way around? Or maybe some doc links. <sorry if the question is too dumb, I have just started with the xwiki> thanks
