what is the best way of converting xsd to xml?

Answer 1

There are a set of tools that you could accomplish this task.
XBinder XML Schema Compiler ( http://www.obj-sys.com/products_xbinder.shtml ) is one of them.
Similar tools (many open source) also exist for Java such as Castor and JAXB.

An open source tool which I use is great:

Good Luck, you obviously should understand both syntax;s before continuing.

Answer 2
