xml-dev - Re: create valid XML from DTD and database

[mark hu <mark@fintrack.com>]

Hi, there:
    The way I mention the hashmap is like this: on the server side you init
your hashmap to host all the method calls which in turn to construct your
XML structure ( this will provide you a helper object which can be used at
client side Applet - data pumper ), and if you are talking about any generic
database and XML rendering - e.g. you are coding in JAVA, I assume you are
using JDBC (ver ??), and the most generic way is to use ResultSet to get the
data and construct your own XML - then you will feel the need for HashMap
which mapping the XML tag and you data fields, and the way you represent DTD
is to load you DTDs into your XML structure, if you want to do
post-processs, you ahve to wait till the whole document finished loading
..... I do not get the idea why you use " ResultSetMetaData " ?????? if you
want to create valid XML from DTD and database, I believe this is the right
way, cause it works anywhere - let me know if I get you wrong.
