Get Type Information of Element
Hallo,
I am working on a project using XML as the query
language. To process the query, I need to validate
the query, which is a xml file, against a specified
XML Schema, then transform the element in the query
into interne presentation. I would like to know
whether I can get the type information of an element
or an attribute, e.g. string, integer, that is
defined in the XML schema as I am parsing the XML
file. How can I do it using Xerces-Java?
Thanks in advance,
zhou

Hallo, Xueming,
thanks for your information. You are right that the
type infomation of the element/attribute could be
found by searching through the XML schema. However,
it maybe very complex to determine the base type of an
element whose type is nested definied by extension/restriction
of base type. Are there some predefined APIs to
determine the base type of an element/attribute?
thanks in advances,
zhou

I am not sure if I fully understand your questions.
I try to give a bit of hints.
Sure, you can get the type of an element, after all the
XML schema is a XML file. I belive it is best addressed
by Xpath.
