what is a mature api / solution for this problem ?

1. user always submit XML document from page, the server side need to save this xml data to sql database.

2. user could add/delete field (node) in the Runtime, server side should detect this modification and make change on sql database accordingly.
for example, user add a new field "age", then it should add a new column in database and save this "age" data into database.

3. when retrieving data from database, it will generate xml file base on table metadata .

In order to detect a change you will have to parse the input document. The standard Java library for DOM will certainly handle this.

I suggest that you work on understanding DOM parsing outside the client-server environment until you are confident that your code can:

1. Catch badly formed xml.
2. Locate the values of all parts of the document.
