what do you *really* want to do?
do you want a generic xsd-to-xml generator? Something that can contrive XML
documents from any general XSD?
or is there a particular XSD you want to generate for?
one approach I have used is to use "xsd.exe /c" to generate classes, then
just instantiate the classes. Serialization of an instance of said class
produces an XML document that conforms to the XSD. example: http://www.winisp.net/cheeso/srcview...ile=Xsd2xml.cs
However, xsd.exe supports only a subset of W3C XML Schema. For example,
lists (as elements) are not well supported.

What I really whant, is the following:
I receive a xml instance and load it into XmlDocument. I have a XSD
specifying the full XML for the xml instance I have received. I now want to
iterate throw the xsd tree with a foreach-node/foreach-attribut the same way
as I can do it with my XmlDocument instance. I need this because I need to
do some comparison with the xml instance and the xsd and maybe fill in some
"blank" values in the xml instance (not just a simple validate againt XSD).
The XSD can be severel different XSD's and therefore I can't use the
"xsd.exe /c".
Hope you have a good idea on how to do this. I don't know much about working
with XSD in .Net.

Read in the Schema and walk through it. One way to do it: build a map in
memory of required and optional fields, and then walk the XML DOM to
determine which elements are present or not present. It sounds messy and
tedious.
see this for a hint: http://www.fawcette.com/xmlmag/2002_...hlin_09_03_02/ The XSD can be severel different XSD's and therefore I can't use the
"xsd.exe /c".
The possible use of multiple XSDs does not prevent you from using xsd.exe.
For example, you could have 3 or 4 (or more) sets of classes derived from 3
or 4 (or more) XSDs. Then you get can object programming semantics rather
than XML parsing.
Example, you de-serialize the XML file into an instance of Class1, then
examine the fields in that instance of Class1 to see if they have been set.
// Class1 is generated from xsd.exe /c (From a given XSD)
XmlSerializer s= new XmlSerializer(t ypeof(Class1));
Class1 c= s.Deserialize(t hefile);
if (c.Field1==null ) c.Field1= Field1DefaultVa lue;
//etc
Actually, by modifying the generated source for Class1, you could insert
"default" values in the instances by modifying the default ctor. These
"default" values would be over-written when de-serialiing a document that
actually has values for them. Going with this approach, you wouldn't need
to
if (c.Field1==null ) c.Field1= Field1DefaultVa lue;
//etc
....because all that would be done implicitly. On the other hand if you have
more complex rules for which fields need to be set (eg, relationships
between one field and another), then this tweak may not work. but xml
serialization still may be a nice simplification.
Though I agree, XML serialization (and xsd.exe) does not work if there is an
*infinite* number of possible XSDs.

Thanks for your input.
I need the class to be dynamical so it can load any XSD without privious
knowledge, and therefore I can't use the "xsd.exe /c".
Also the "default" values are dependent on the xml instance and therefor I
can't use the "default" values from the XSD.
Basically I loop throw the xml instance I have received, and for every node
with one or more attributes filled out, I need to check in the xsd if there
exist more attributes to this specific node, and if there does, I need to
fill them with a blank value in the xml instance.
I have found out how to load the XSD ind a XmlSchema class and I have the
xpath to the specific node, for which I need to check if it has any
attributes. I just don't know how to "navigate" throw a XmlSchem instance,
and get the list of attribute names this specific node has.
Any ideas?
