Getting elements from a XSD Complex Type - ATL [message #1228778]

Hi guys,

My transformation is XSD -> UML
I tried a little bit everything to get the elements from a complex type or to know with which complex type an given element is related to (if any):

Here is .xsd file example:

<xs:element name="sayGoodbye" type="tns:sayGoodbye"/>

<xs:element name="sayGoodbyeResponse" type="tns:sayGoodbyeResponse"/>

<xs:element name="sayHello" type="tns:sayHello"/>

<xs:element name="sayHelloResponse" type="tns:sayHelloResponse"/>

<xs:complexType name="sayHello">
<xs:sequence>
<xs:element name="arg0" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>

<xs:complexType name="sayHelloResponse">
<xs:sequence>
<xs:element name="return" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>

<xs:complexType name="sayGoodbye">
<xs:sequence>
<xs:element name="arg0" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>

<xs:complexType name="sayGoodbyeResponse">
<xs:sequence>
<xs:element name="return" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>

By now.. I couldn't get the list of elements from a XSD!XSDComplexTypeDefinition (if is really here I will find).. or to get the complextype related to a XSD!XSDElementDeclaration. If anyone could help me.

Many thanks in advance

Michel,

Of course if you're using the XSD model, you'll have to look closely at
that model to understand the structure you'll have to navigate using
ATL. Have you done that? Base on that, what specifically have you tried?

Hi Ed Merks...

I figured out how to get them. Doing:

s.contentType.content.contents.first().content.name (only the first here)
's' being a XSD!XSDComplexTypeDefinition

Trying to write the transformation.. I just could see "s.contentType". When I tried to use the shortcut (ctrl + space) to see what I could get from "s.contentType.(ctrl + space) this ".content" option was not available.. in some way it was hidden. Only in debug mode it was possible to access.. I don't know why.

Now I'm trying to get the list of ComplexType inside a XSD file.. I can only see the list of Element Declaration (elements). Maybe the same happens..

Michel,

Yes, the XSD model is quite complex and the elements in a complex type
are part of complex content's particle structure which is in general a
tree structure that can nest arbitrarily deep. You might find it
helpful to use the Sample XSD editor that comes with the XSD SDK in
order to view/understand the tree structure as well as the logical
semantic structure of an instance to better understand how to navigate it.

Hi Ed Merks,

thanks for your advice. I'll take a look at it!
