Hi ! my all meta-models are registered,i want to read the xmi:id field of the model file but unable to retrieve its value,any suggestion?

model file :

<?xml version="1.0" encoding="UTF-8"?>
<notation:Diagram xmi:version="2.0" xmlns:xmi="[url]http://www.omg.org/XMI[/url]" xmlns:xsi="[url]http://www.w3.org/2001/XMLSchema-instance[/url]" xmlns:abcd="[url]https://petrinetdsl[/url]" xmlns:ecore="[url]http://www.eclipse.org/emf/2002/Ecore[/url]" xmlns:notation="[url]http://www.eclipse.org/gmf/runtime/1.0.3/notation[/url]" xmi:id="_vSD84LHJEeq1h8ti2UwKzQ" type="Petrinetdsl" name="default.petrinetdsl_diagram" measurementUnit="Pixel">
<children xmi:type="notation:Node" xmi:id="_qLutgLHPEeqGGrut8ExKFg" type="2001">
<children xmi:type="notation:DecorationNode" xmi:id="_qLxJwLHPEeqGGrut8ExKFg" type="5001">
<layoutConstraint xmi:type="notation:Location" xmi:id="_qLxJwbHPEeqGGrut8ExKFg" x="-78" y="7"/>
</children>
<styles xmi:type="notation:DescriptionStyle" xmi:id="_qLvUkLHPEeqGGrut8ExKFg"/>
<element xmi:type="abcd:Place" href="default.petrinetdsl#//@places.0"/>
<layoutConstraint xmi:type="notation:Bounds" xmi:id="_qLvUkbHPEeqGGrut8ExKFg" x="259" y="175"/>
</children>

my code for reading different key and values

[for (aNode: Node | aDiagram.children)]
[aNode/]
[/for]

[aDiagram.children.element/]
[aDiagram.children.styles/]
[aDiagram.children.layoutConstraint/]

Thanks!

Hi Fatima,

As you seem to be using Acceleo to query your model I'd suggest posting this message to the Acceleo forum instead.

Thanks,
Dimitris

Hi! Thanks for your reply! I did it there as well! suppose if i am not using acceleo, is there any way to get the value which are like xmi: id , xmi:type , href= ""?
model file is this :

<children xmi:type="notation:Node" xmi:id="_qLutgLHPEeqGGrut8ExKFg" type="2001">
    <children xmi:type="notation:DecorationNode" xmi:id="_qLxJwLHPEeqGGrut8ExKFg" type="5001">
      <layoutConstraint xmi:type="notation:Location" xmi:id="_qLxJwbHPEeqGGrut8ExKFg" x="-78" y="7"/>
    </children>
    <styles xmi:type="notation:DescriptionStyle" xmi:id="_qLvUkLHPEeqGGrut8ExKFg"/>
    <element xmi:type="abcd:Place" href="default.petrinetdsl#//@places.0"/>

Thanks in advance!

Hi Fatima,

I've added a small example that shows how you can query GMF diagrams (as opposed to their underlying models) with EOL in https://git.eclipse.org/c/epsilon/org.eclipse.epsilon.git/tree/examples/org.eclipse.epsilon.eugenia.examples.friends.models.

Thanks,
Dimitris

Hi Dimitris! Thanks again for a quick reply! i have seen the above example;it is like

friends model example:

for (shape in Shape.all) {
	shape.id.println();
	shape.layoutConstraint.println();
	shape.element.type.println();
}

which i have done by :

[aDiagram.children.element/]
[aDiagram.children.styles/]
[aDiagram.children.layoutConstraint/]

and:

[for (aNode: Node | aDiagram.children) ]
   x="[aNode.layoutConstraint.eGet('x')/]" 
   y="[aNode.layoutConstraint.eGet('y')/]" 
   width="[aNode.layoutConstraint.eGet('width')/]" 
   height="[aNode.layoutConstraint.eGet('height')/]">[/for]

the problem is that i can get the value of any node and edges (which are in form of type, x,y, width,height,source and target etc ) but not like xmi:id etc.
Type value of node are not unique there are repeating in model so i need to use the value of xmi:id which is unique for every node and edge. :(

Hi Fatima,

I'm sorry, I don't know how Acceleo exposes the XMI id of model/diagram elements.

Thanks,
Dimitris
