XSD & Xpand (for xmt2test) [message #494539]

Hi,

I found a tutorial for XSD and Xpand for oAW 4.3.1. This is exactly what I want to do. But how can I do with the current version integrated in eclipse Galileo?

When I create a Xpand project I do not have the XSD option.

Please help me. This tool combination would be sooo cool.

br,
Marco

Hello Marco,

there is no problem to create a xml 2 text project using the XSD Adaptor that moved from oAW to Eclipse too.

Here are the Steps you have to do:

Creste a New Xpand Project
Go to your projects Properties and select XSD Metamodels in the Xtend/Xpand Section
place your XSD and XML File somewhere in a Source Folder

Create your workflow (adjust the one from oAW 4.3.1 to the new Classes. The result might look like this


	
<workflow>
	<!-- load the file -->
	<component class="org.eclipse.xtend.typesystem.xsd.XMLReader">
		<modelSlot value="model" />
		<uri value="model/mysetup.xml" />
		<metaModel id="mm"
			class="org.eclipse.xtend.typesystem.xsd.XSDMetaModel">
		</metaModel>
	</component>

	<!-- clean up the target directory -->
	<component
		class="org.eclipse.emf.mwe.utils.DirectoryCleaner">
		<directory value="src-gen/mypackage" />
	</component>

	<!-- generate some code -->
	<component class="org.eclipse.xpand2.Generator">
		<metaModel idRef="mm" />
		<expand value="templates::wizard::Root FOR model" />
		<outlet path="src-gen" />
		<beautifier
			class="org.eclipse.xpand2.output.JavaBeautifier" />
	</component>

</workflow>

adjust your projects dependencies
run the workflow

Hi Christian,

Thanks for your help.

Still I don't know how to match my template with the names of the workflow and the model.

I start with this template:
«IMPORT metamodel»

«DEFINE Root FOR breakdownXml::BreakdownXmlDocumentRoot»
«FILE "breakdown.xxx"-»
«this.toString()»
BREAKDOWN:
«ENDFILE»
«ENDDEFINE»

and get this error from the workflow:

SEVERE: Error in Component of type org.eclipse.xpand2.Generator:
EvaluationException : No Definition 'template::Template::Root for type::AnyType' found!
[23,41] on line 1 'EXPAND template::Template::Root FOR model'

As you might see I am a complete beginner with XPand and EMF. So please do not hesitate to mention basics.

Pease help me further.

br,
m

could you please post your workflow / xsd / xml and folder structure.
and check if you use inhertiance in your metamodel - then you have to place the definition for the subtypes as well as for the supertype to match xpands polymorphim requirements

your root element is a named root that has an anonymous complex type. these types are mapped to the EClass [[elementName]]Type. so in your case the root Element is of type metamodel::RootType and your template should looklike this

«IMPORT metamodel»

«DEFINE Root FOR RootType»
«FILE "breakdown.stm"-»
«this.toString()»
BREAKDOWN:
«ENDFILE»
«ENDDEFINE»

fore more information how xsd constructs are mapped to ecore construct have a look at http:// www.eclipse.org/modeling/emf/docs/overviews/XMLSchemaToEcore Mapping.pdf

The result has not changed.

So still
'template::Template::Root for type::AnyType'
does not match
«DEFINE Root FOR metamodel::RootType» (also tried just RootType)

yes the other thing is that you xml should use xsd / refer to xsd
therefore the xsd should look like this

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xs:schema xmlns="http://www.example.org/test" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.org/test">
<xs:element name="root">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" ref="Breakdown"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="Breakdown">
<xs:complexType>
<xs:sequence>
<xs:element ref="DictDetail_Name"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="DictDetail_Name">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:NCName">
<xs:attribute name="Type" type="xs:NCName" use="required"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
</xs:schema>

and the xml like this

<?xml version="1.0" encoding="ISO-8859-1"?>
<root xmlns="http://www.example.org/test"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.example.org/test metamodel.xsd ">
<Breakdown>
<DictDetail_Name Type="String">abc</DictDetail_Name>
</Breakdown>
</root>

or try the other possibilities described at http:// help.eclipse.org/galileo/index.jsp?topic=/org.eclipse.xpand. doc/help/ch04s05.html

Thanks again for the suggestion.

I tried it all, except the import variant, but the result is still the same.

There is no message about a missing xsd.

Any more ideas?

hi, of course you have to class the right template from your workflow. in your case this might look like this

<component class="org.eclipse.xpand2.Generator">
		<metaModel idRef="mm" />
		<expand value="template::Template::Root FOR model" />
		<outlet path="src-gen" />
		<beautifier
			class="org.eclipse.xpand2.output.JavaBeautifier" />
	</component>

and you have to add some additional dependency

com.ibm.icu
