[Expat-discuss] Well formedness Validation not proper in EXPAT

[devyani.sapre at wipro.com]

Hi rolf,

Thanks a lot for clarification , I verified it with both xerces and
expat and they are treating such an entry as wellformed only. But if I
have  a ">"  at the end of the last tag of the file (as given below) ,
both throw an error. Can you please explain me this behaviour too???

Eg:

<doc>
 	<name1>devyani</name1>>>>> 
	<name2>raj</name2>
</doc>>>


Thanks
Devyani

I would concur with rolf's interpretation. Note that section 2.4 of the
XML specification states:

The ampersand character (&) and the left angle bracket (<) MUST NOT
appear in their literal form, except when used as markup delimiters, or
within a comment, a processing instruction, or a CDATA section. If they
are needed elsewhere, they MUST be escaped using either numeric
character references or the strings "&amp;" and "&lt;" respectively. The
right angle bracket (>) MAY be represented using the string "&gt;", and
MUST, for compatibility, be escaped using either "&gt;" or a character
reference when it appears in the string "]]>" in content, when that
string is not marking the end of a CDATA section.

So, the < character in the character data would constitute a violation
of well-formedness. But, the same does not hold true for >. So, the
document is well formed and xerces is complaining about something it
should not complain about.

Reid.
