SYMPTOMS
When you parse or load XML base64 encoded data with the MSXML parser version 2.0a and the data contains the slash mark (/) character, you may receive the following error message:

Run-time error '-2147467259 (80004005)':

Error parsing '...' as bin.base64 datatype.



CAUSE
The base64 character set contains the following characters, with decimal values ranging from 0 to 63: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/ The MSXML parser version 2.0a (Msxml.dll, file version 5.0.2314.1000) that ships with Internet Explorer version 5.0a recognizes the asterisk (*) instead of the slash mark character (/) of the Base64 character set.



RESOLUTION
The bug has been fixed in the MSXML parser version 2.5a (5.0.2919.6303), which ships with Internet Explorer version 5.01 and in later versions of the parser.



STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
