To do this in WebDNA, I would use ConvertChars with a custom database that just converts ASCII characters into their numeric character references (so "a" would be converted to "a" and b would be converted to "b" and so on). I don't have such a db but I bet somebody on the list would. Hope that answers the question. -- Dana ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list .
