Wouter and All,
thank you very much for all your replies! Noew thanks to this function, we can probe a string to see if it is Base64 encoded and add it as a <base64> item in the XML-RPC Lib!
Thanks andre
Tnx, but I should learn to use the find and replace instead of replacing by hand and watching movies, damn me...as you all have seen already
One could test for a *welformed* base64Encodeded string :
function isWelformed64 pText replace cr with "" in pText
if the num of chars in pText mod 4 = 0 then
repeat for each char i in pText
put i into tArray[i]
end repeat
put the keys of tArray into tKeys
if "=" is in tKeys then
put the num of chars in pText - 1 into x
put 1 into tC
repeat for each char i in pText
if i = "=" and tC < x then return false
add 1 to tC
end repeat
end if
repeat for each line i in tKeys
if i is not in "abcdefghijklmnopqrstuvwxyz1234567890/=" then return false
end repeat
return true
else return false
end isWelformed64
Sorry once again. Greetings, WA
