My opinions:

1. First of all, one minor correction: SAX is not a W3C standard.
2. I don't think this is a practical idea, because as someone has mentioned, it is going to involve too much of reflection overheads and messy code generations. But, even if we do that, what are we going to achieve by that? If your idea is to generate strongly typed application specific Xml datastructure for an Xml instance, you can take a look at JAXB.


Thanks,

Hi All,

W3C defines specific methods witihn a SA ContentHandler like
startElement(), endElement() etc... that would be called back when
elements are encountered within the XML Document.
User overrides these methods to define the logic within each of these
callback methods.

As an alternative, what if the User defines explicit methods like

public void startEmployee() [simplified here- ignoting namespace mappings]
public void endEmployee()
public void onEmptyAdddress()
public void onAttr_Employee_Name() [this is just illustrative of the
attributes scenario.]

Advantage
-----------------

Cleaner separation of logic.

Disadvantages
---------------------

No Clear contract.

This is only an ilustrative subset of the functionalty.
What do you folks think of this ? Is this a better alternative ?
