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

[Fisher, Paul_K (Houston)]

Because then the extra ">" characters are considered content after the root element of the document is closed.

	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.
