generating xml-structured file beside the generated xmi file [message #839844]

Hello All,

I'm trying to generate xml-structured file beside the already generated xmi file, the problem is i got lots of nested elements...so i need to loop for all the created elements and create the file accordingly.

Is there any way that i could loop for all the created elements after saving the file not while writing and modifying it? (because while writing is going to be kinda messy)

below you can find the generated XMI structure, my structure should be quite similar too:

<?xml version="1.0" encoding="UTF-8"?>
<umlt:ModelUMLT>
<packagedElement xsi:type="umlt:PackageUMLT">
<packagedElement xsi:type="umlt:TransformationActivity">
<node xsi:type="umlt:StructuredTransformation">
<node xsi:type="umlt:TransformationAction">
<ownedMapping>
<ownedAssignmentDef name="a.b:=7">
<ownedExpression xsi:type="uml:Expression">
<name xsi:nil="true"/>
<symbol xsi:nil="true"/>
<operand xsi:type="uml:OpaqueExpression">
<name xsi:nil="true"/>
</operand>
<operand xsi:type="uml:OpaqueExpression">
<body xsi:nil="true"/>
</operand>
</ownedExpression>
</ownedAssignmentDef>
<ownedAssignmentDef name="a.b.c:=3">
<ownedExpression xsi:type="uml:Expression">
<name xsi:nil="true"/>
<symbol xsi:nil="true"/>
<operand xsi:type="uml:OpaqueExpression">
<name xsi:nil="true"/>
</operand>
<operand xsi:type="uml:OpaqueExpression">
<body xsi:nil="true"/>
</operand>
</ownedExpression>
</ownedAssignmentDef>
</ownedMapping>
</node>
<node xsi:type="umlt:TransformationAction">
<ownedMapping>
<ownedAssignmentDef name="a.b.c.d:=15">
<ownedExpression xsi:type="uml:Expression">
<name xsi:nil="true"/>
<symbol xsi:nil="true"/>
<operand xsi:type="uml:OpaqueExpression">
<name xsi:nil="true"/>
</operand>
<operand xsi:type="uml:OpaqueExpression">
<body xsi:nil="true"/>
</operand>
</ownedExpression>
</ownedAssignmentDef>
</ownedMapping>
</node>
</node>
</packagedElement>
</packagedElement>
</umlt:ModelUMLT>

Thanks in Advance and happy easter:)

Resource.eAllContents will walk the whole tree...

I don't follow what you're asking...

well, thanks for your quick reply...

let me show you the complete scenario:

-Create the diagram
-create the elements inside that diagram.
-saving the diagram should fire the event for looping for all the elements and creating the xml-structured file accordingly.

i have checked the eAllContents method and googled it and indeed that's what i need according to the online documentation!
TreeIterator<EObject> treeIterator = diagram.eAllContents();

but the point is i couldn't retrieve all the elements in my diagram...below is a code snippet i created for retrieving the diagram's elements:

org.eclipse.emf.ecore.resource.Resource diagramResource = umlt.diagram.part.UMLTCreationWizard.getDiagram();

TreeIterator<EObject> treeIterator = diagramResource.getAllContents();

while (treeIterator.hasNext()) {

EObject diagramEl = treeIterator.next();

String name = diagramEl.eClass().getName();

System.out.println("diagramEl.eClass().getName(): " + name);

}

the expected output was all the elements' names within that diagram, while the current output ist:
diagramEl.eClass().getName(): Diagram
diagramEl.eClass().getName(): DiagramStyle

please have a look over the attached snapshot to get a clearer idea on how to diagram looks like
index.php/fa/7842/0/

thx!
mostafa.

What does the XML for this resource look like? I imagine it only has
these two levels of nesting...

Hi Ed,

do you think a model2text transformation language could help moustafa further? This could take care of a lot of things which he would need to do by hand otherwise.

Ralph,

I suspect that he wants to create some model and serialize it as
XML/XMI, but it's all been pretty vague so far...

Hey Ed,

the model looks like the snap shot below:
index.php/fa/7899/0/

and for the xmi structure:

<ownedMapping>
<ownedAssignmentDef name="a.b.c.d:=7">
<ownedExpression xsi:type="uml:Expression">
<name xsi:nil="true"/>
<symbol xsi:nil="true"/>
<operand xsi:type="uml:OpaqueExpression">

=========================================================

i've also tried working with some other way for showing the view but it only shows the hierarchy and not all the contents...
So for example if i got a schema like the following:

ModelUMLT --> PackageUMLT --> TransformationActivity --> Structured Transformation Activity --> Mapping Rules --> Assignment Definition

if i got single Assignment Definition the result will be the same as if we got a couple of Assignment Definitions...

may i ask another piece of question?
at what event/method exactly does the xml/xmi file is generated? when we add new elements to our diagram and save the file, the xml/xmi file is updated accordingly, which event is called then?

well to make it clearer i am trying to find where and how does the editor itself generate the xml/xmi structure...

Hi,

take a look at the generated xxxDiagramEditor and its performSave method.

Cheers,

Ralph

Hey Ralph,

I checked that class but i didn't find that method, i found: "performSaveAs" and "doSaveAs" methods though!

at the xxxDocumentProvider class there's another method performing the same functionality which is "doSaveDocument"

Thanks a lot for your help!

mostafa.
