Hi all,
I wrote some generator of classes from XSD files but encountred unexpected (for me) values in parsed DOM.
First I load XSD with XmlSchema.Read() method, then iterate through XmlSchemaElements. I have a function
IsComplex() which return bool value if it has simple content (e.g. type string, int,...) or complex one (sequence,
choice, ..). This function looks like this:
bool IsComplex(XmlSchemaElement el) {
if (el.SchemaType is XmlSchemaComplexType) {
XmlSchemaComplexType t = (XmlSchemaComplexType)el.SchemaType;
if (t.ContentModel is XmlSchemaSimpleContent)
return false;
else
return true;
}
else
return false;
}
but when I use definition of type within XSD, SchemaType property of element returns null. I would expect here
instance of XmlSchemaComplexType. However SchemaTypeName is not null and contains correct value
(PackageList for example bellow).
Is it correct behaviour ? Is there better approach how to recognize content of schema element ?
Here's sample of XSD:
<?xml version="1.0" encoding="utf-16"?>
<xs:schema xmlns="http://test.shipments" targetNamespace="http://test.shipments" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="shipments">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="unbounded" name="shipment">
<xs:complexType>
<xs:sequence>
<xs:element name="shipment_reference" type="xs:string" />
<xs:element name="packages" type="PackageList" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:complexType name="PackageList">
<xs:sequence>
<xs:element name="package_reference" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:schema>
Thanks for any help,

You must compile your schema using XmlSchema.Compile and then access the ElementType property to obtain an instance of the XmlSchemaType corresponding to the type in the schema.

Thanks a lot, it works as I need.
However, MSDN class library is poor documentation for using SOM, is there some good source of information on working with SOM ?
I would rather avoid this try-fail approach next time.
