An XML parser isn't guaranteed to return the entire contents of a tag in a
characters callback. It is free to break on every byte, or newlines, or
entities, or...

So your application is most likely expecting all the base64 string, but
only getting part of it. Use a buffer to bundle it all together, and
process the string in the call to end_element.
