Aha. So, as I thought, the very last stage of output probably isn't the most sensible place to edit anyway. So... * do you want these extra "phrases" to be inserted "on demand", when you edit the page to include special syntax? If so, look at the extensions mechanism - http://meta.wikimedia.org/wiki/Write_your_own_MediaWiki_extension * do you want these extra phrases to be inserted in reaction to certain words or phrases, or existing markup elements, appearing in the content (without having to actually add anything to the page)? [Or indeed, to appear as though they were part of the content, but on every single page - though this would seem a case for modifying the skin to me] If so, add a function in Parser.php and have it called from the internalParse() function. * do you want these extra phrases to be inserted into the actual source text, not just the output? If so, either write a bot or a script talking to the database to add them en masse, or call a function from Parser::preSaveTransform() or pstPass2() so that they will be added to the article as it is saved (and beware of adding them twice :p) * are none of these really what you're trying to do? In which case, perhaps you could explain in more detail what you're trying to do, and I'll endeavour to find the logical place for it to be done. Oh, and finally, see docs/hooks.doc (or .txt) in the source distribution, which describes a system for creating extensions which insert code at various points without actually modifying the code. In fact, I hope you read this far, because that may be more helpful than my suggestions [although the version I just looked at doesn't list a hook for ArticleShow - a mistake, surely?] -- Rowan Collins BSc [IMSoP]
