Hi,
I'm looking for the best way to work with a datatyped
xml document. I've read the validation section in the
cookbook and had a flick over the relevant jdocs, but
I am still unsure of how to accomplish what I want.
For instance, lets say I have an xsd schema and
document po.xsd and po.xml. (PurchaseOrder) And one of
the elements is a Price which is required and typed as
Integer
I first validate the po.xml against po.xsd then create
the Document. (<-- not quite sure how to do this but
it shouldn't be too hard)
Now that I have the document, I want to be able to
determine the Datatype of an element or attribute so I
can act accordingly, how do I this?
I would need this in a situation where I have a List
of PO's and would like to sum the prices of all the
PO's. However, the above situation is determined
dynamically and I can't hard code anything in because
I don't know what type of document I'll be getting, I
just know that I might have to add different fields in
any schema and document pair.
I would like to be able to do something like:
Element price1 = doc1.getElement("Price")
Element price2 = doc2.getElement("Price")
if(schema.getDataType(price1) == Integer) {
int price1Int = Integer.parseInt(price1.getText());
int price2Int = Integer.parseInt(price2.getText());
System.out.println(price1Int + price2Int);
}
else if (schema.getDataType(price1) == Float) {
etc etc
}
Whats the best way to go about something like this?
Regards,
Beri
