Initial Comment:
<Test>
<Row>&#60;OK&#62;</Row>
</Test>

For the test case above, I assume the result in 
void characterDataHandler(void *userData, const 
XML_Char *s, int len)
{
}

*s should be "&#60;OK&#62;"
but the result I got was "<"

Is it a bug or by design?

Thanks.

I don't think it's a bug. I'll change my code to follow the 
standard. :-)
Please close it.

Thanks.

The definition of XML_Char in Expat depend on how Expat
is compiled:
- XML_UNICODE defined: 
  XML_Char = ushort
- XML_UNICODE and XML_UNICODE_WCHAR_T:
  XML_Char = wchar_t
- otherwise:
  XML_Char = char

Yes, it was not my faulty memory, but my faulty eyes, too.

const XML_Char* s, int len

means, that you get block of XML_Chars in "s", in which
first "len" XML_Chars have meaning. I don't know, what
XML_Char means in your expat. It could be char, or wchar_t,
so one problem is that you treat string "s" as char string when
it is wide-char string (and all you see is first "<\0" sequence),
or you shouldn't use *s (which means "XML_Char at zero
index", hence you get a '<' char), and use s instead
(remembering "len" stuff)

And what you got was probably "<OK>" (if my guessing for 60 
and 62 chars is correct), but in wide (16b, 2-bytes), not old, 
one-byte characters. So "<" 0 "O" 0 "K" 0 ">" 0 and trailing 
duble-0 for end-of-string-zero-char. Latter may be my faulty 
memory, for callback have probably just block and its width, 
not wide-character C-string :) ). Hoping it wasn't to messy.

According to section 4.4 in the XML specs
(XML Processor Treatment of Entities and References)
the behaviour of Expat appears to be correct.
