Some advice for a VB programmer who is new to XML.

[wxdqz]

I'm new to XML and have read a book and taken a CBT class and there arestill some things that are still a little mysterious to me.I need to put together a VB program that will pull and process datasourced from 5 different repositories. 2 of them have some mechanismthat exports the data in an XML format the other 3 will happen sometimein the future. Questions:1) How should I architect the exchange of data between theserepositories and my application. The data is not storedin XML format hence there is some utility that createsthe XML file. Which is not going to be of any use to mebecause I'm querying the database.2) Is there some generic XML parser everyone is using or do I have towrite my own?Thanks in advance for any help.James
