How to Read XSD values into text file using .NET?

string xsdFile="<xs:simpleType name="file-number"><xs:union><xs:simpleType><xs:restriction base="xs:integer"><xs:totalDigits value="3"/>
<xs:minInclusive value="1"/><xs:maxInclusive value="999"/></xs:restriction></xs:simpleType><xs:simpleType><xs:restriction base="xs:string">
<xs:whiteSpace value="preserve"/><xs:enumeration value=""/>
</xs:restriction></xs:simpleType></xs:union></xs:simpleType>";
var document = XDocument.Load(xsdFile);
var nodes = document.Descendents().Where(e => e.Name.LocalName.StartsWith("xs:simpleType"));
foreach(var node in nodes)
{
 // get the node values one by one here
}
