If so, you would get a "char data" callback for a start or end element's end-of-record character (forced to '\n', regardless of the actual EOR char, per the XML spec). By specification, only the characters between the "<>" are considered part of the start/end element -- all other characters are char data. If your parse buffer contains multiple elements and their associated char data, you'd still see the EOR characters in the char data callback (modified as described above). I'm using Expat to parse pseudo-XML data derived from our proprietary markup format, and so i've had to use a combination of "(char_data == '\n)'" and "(buffer_length == 1)", plus a flag in the parser "userdata" to differentiate between the EOR characters at the end of element tags (what i'm discarding), and those EOR characters that represent blank lines in the content (what i have to keep).
