Hi, I have two questions 1). Does DOM parser validate the XML file against DTD? 2). How do you specify numeric validation such as range or Boolean validation in DTD.for example: Say I have <!ATTLIST subsection autoflush (true|false) #REQUIRED> here, I have specified that autoflush should require true|false values when the parser validates the XML against DTD.In the similar way, I reuire that field should only contain the numeric value and can contain range say between 10 to 20. Can anybody explain this with a snippet of code? Thanks Anand.
