I have the following requirements

1. Will be getting a XSD and XML file. Need to validate this XML against the corresponding XSD.

2. Parse the XML file and fetch the data to be inserted into a few custom tables.

3. All this is to be done using PL SQL.


Sorry for very high level requirements...but any pointers to this will be highly appreciated.

Database version is 9i

You can use an XML-schema to define a set of XML-tables. Validating incoming XMLs is done automagically, as well as storing them in these XML-tables.
This is a good way to go if you want the data as XML; if you want it as relational data later on, I'm not sure about it. Last time I worked with it, was years ago, with previous db-versions.
Probably enhanced drastically since.

Back then it was called XDB or XML DB, if you need search terms.

Almost 95% of the requirements match with my previous project, but want to know about registering XSD. Will it be done on table level or JSF class.

we would refrain from using java

Our DB version is 9i and someone suggested that we will not be able to use EXTRACTVALUE(VALUE to extract the values for various tags and attributes.
They said that it is only for 10G and above. But we will be able to use XMLTYPE to validate XML against XSD (we dont know how to do that).

According to our DB version which would be the most apt way to accomplish our task ??

You can use you EXTRACTVALUE() function to extract Values from XML. This doc shows the usage in 9i.

http://www.oracle-base.com/articles/9i/XMLDB9i.php

And register you XSD on XML type table, but be sure that is correct because you cannot change the XSD. You need to drop and recreate again.

Thanks
