Question
How I can store base64 strings in XML?
Do you use CDATA to store base64 strings in XML? Would it help as it allows use of < > within the strings?
Is base64 configurable where you tell it not to use certain chars if they conflict with XML?
Solution
You can just store it as a text or attribute value; no escaping or CDATA
sections needed. The standard base 64 characters +
and /
(other than a-z
, A-Z
and 0-9
) do not interfere with XML parsing at all.
OTHER TIPS
Base64 only uses alphanumeric characters and '+' (plus), '/' (slash) and '=' (equals). No need to encode anything for XML.
There are no characters whatsoever in the Base64 charset that will conflict with XML strings.
