Hi,

can find the position of more than specific character with strchr() function?

e.g.  
i want to search the %album% tag for either ( or [ or + and so on. So i get the first position if one theses characters appears.

I need that for cutting the tag from that position etc.

many thanks!

If you wanted to find pairs of matching simple quotation marks ' and ", that is possible in many engines: (["'])[^"']\*\1 or ("|').\*?$1, or some other combination of matching the start character, optionally advancing and then matching that start character as end character.
