xsd to xml

I have to do generate the xml instance on my own?

In an arbitrary schema you may have option groups, attributes without
default values, etc.
So you'd need to come up with some heuristics for these cases appropriate to
your
application.

Once you've got that you could walk the schema using the SOM to create
such an instance yourself.

There are tools that do this.
Altova's XMLSpy does this, and probably some others as well. You have to
set up the heuristics within the tool.

One of the approaches to instantiate an XML file (I am unfortunately made to
use) is to read XSD file into a DataSet.
This will create a data set of the specified structure.
After that you may use WriteXML(fileName) method to generate and XML file.
There are two potential problems.
1. Not every XSD may be read into data set. Some legal constructions cause
errors while parsing.
2. You'll need to add some information to the dataset before you write XML.
Otherwise you will get an XML file consisting of <YourRootElement /> only.

(Do not forget to set msdata:IsDataSet="true" attribute in the root element
of your dataset, where msdata is
xmlns:msdata="urn:schemas-microsoft-com:XML-msdata".)

Good Luck.

Hello everyone,
I'm trying to generate a xml instance with some default values from a xsd schema with vb.net. I think .net does not provide any classes to do
this, does it? Alternatively are there any third classes namespaces that make this operation or I have to do generate the xml instance on my own?
Thanks to all, Gionni
