I am trying to create a complex XML schema, but I am unsure in how I can define the associations between objects. If I have the two objects shown in the schema below, how could I associate many 'Orders' to the 'Contact' object. <?xml version="1.0" encoding="UTF-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="Contact"> <xsd:complexType maxOccurs="unbounded"> <xsd:attribute name="Name" type="xsd:string" use="required" /> </xsd:complexType> </xsd:element> <xsd:element name="Orders"> <xsd:complexType> <xsd:attribute name="Item" type="xsd:string" use="required" /> <xsd:attribute name="Amount" type="xsd:integer" use="required" /> </xsd:complexType> </xsd:element> </xsd:schema> I couldn't find any resources in the Mendix documentation, of course I could have missed something, so any resources would be good.
You can define your "orders" as just complex type and refer it to the element in your main object, so something like :
Thanks for the help, the reference you posted was really useful. In an extension to this, is there a way to have multiple level children - I need to make one that is 4 layers deep.
In Mendix it is not possible to map a recursive structure. If you know that you will have a maximum of 4 levels, then you have to manually map them. The drawback of course is that if you decide to change something, you have to change the mapping in al 4 layers.
