I need to help a user converting his old infoboxes to the new ones. Problem is, the old infoboxes use unnamed parameters and generally a bad syntax. Let's use this page as an example, I'd like to make a regex for AWB (or if there are better tools, tell me, I know you can use th advance find and replace settings to probably do something about it) to convert the infobox template from
{{Personaggio|[[File:Arzakon.jpg|265px]]|Arzakon|[[Piani del Multiverso|Piano Sconosciuto]]|Data Sconosciuta|Sconosciuta [[Planeswalker]]|-|Sconosciuto}}
to something like
{{Personaggio | par1 = [[File:Arzakon.jpg|265px]] | par2 = Arzakon | par3 = [[Piani del Multiverso|Piano Sconosciuto]] | par4 = Data Sconosciuta | par5 = Sconosciuta [[Planeswalker]] | par6 = - | par7 = Sconosciuto }}
