Hi every body,
I have a problem when i want to transform an XML to another XML in ATL.
When i want to translate a root vers the other root, i have this error "Cannot set feature children to value [org.eclipse.emf.ecore.impl.DynamicEObjectImpl@106c28e (eClass: org.eclipse.emf.ecore.impl.EClassImpl@45a13b (name: Attribute) (instanceClassName: null) (abstract: false, interface: false)), org.eclipse.emf.ecore.impl.DynamicEObjectImpl@22610b (eClass: org.eclipse.emf.ecore.impl.EClassImpl@15c4245 (name: Text) (instanceClassName: null) (abstract: false, interface: false)), org.eclipse.emf.ecore.impl.DynamicEObjectImpl@cf16e8 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@e25e24 (name: Element) (instanceClassName: null) (abstract: false, interface: false)), org.eclipse.emf.ecore.impl.DynamicEObjectImpl@1112380 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@15c4245 (name: Text) (instanceClassName: null) (abstract: false, interface: false)), org.eclipse.emf.ecore.impl.DynamicEObjectImpl@122d2ad (eClass: org.eclipse.emf.ecore.impl.EClassImpl@e25e24 (name: Element) (instanceClassName: null) (abstract: false, interface: false)), org.eclipse.emf.ecore.impl.DynamicEObjectImpl@31d83c (eClass: org.eclipse.emf.ecore.impl.EClassImpl@15c4245 (name: Text) (instanceClassName: null) (abstract: false, interface: false)), org.eclipse.emf.ecore.impl.DynamicEObjectImpl@1a71ca6 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@e25e24 (name: Element) (instanceClassName: null) (abstract: false, interface: false)), org.eclipse.emf.ecore.impl.DynamicEObjectImpl@6b5372 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@15c4245 (name: Text) (instanceClassName: null) (abstract: false, interface: false))], inter-model references are forbidden. Configure launching options to allow them."

I didn't understand this error.

So, i need your help and this is my Root rule.
rule ROOT {
from
i : XMLS!Root
to
o: XMLC!Root (
name <- 'donneesMUDU',
startLine <- i.startLine,
startColumn <- i.startColumn,
endLine <- i.endLine,
endColumn <- i.endColumn,
children <- i.children

)
}
what should i do!

Thank you,
Samar

Hello,

The error message says "inter-model references are forbidden. Configure launching options to allow them".
You should try to set the corresponding option to yes in your launch configuration and then run your transformation again.
Maybe this could solve your problem.

Thanks,
but when i execute this is the result:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="/projet2/metamodele/XML.xml">
<Root startLine="1" startColumn="1" endLine="11687" endColumn="13" name="donnees"/>
<Element name="OccurrenceDeComposant">
<children xsi:type="Attribute" name="typeComposant" value="F"/>
<children xsi:type="Attribute" name="repere" value="054"/>
<children xsi:type="Attribute" name="uid" value="83678fd1a6ab"/>
</Element>
.....
the root is not for all the element.

So how can i do to have the root containes all the element.


Thank you,
Samar

Hello,

You first have to ensure that, in your XML.ecore file (i.e. your XML metamodel), the "children" reference is actually a containment one.
Then, this can also depends on your input model (is it correct?) and on the other rules in your transformation.

Hi,
After the XML2XML transformation ,I have as a result an xmi like this :

<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="XML">

<children xsi:type="Attribute" name="typeComposant" value="F"/>
<children xsi:type="Attribute" name="r" value="015"/>
<children xsi:type="Attribute" name="uidComposant" value="1235"/>
</children>
</Root>
<Root name="m">
<children xsi:type="Element" name="composant">

<children xsi:type="Attribute" name="r" value="157"/>
<children xsi:type="Attribute" name="uidComposant" value="8320"/>
</children>
</Root>
<Root name="m">
<children xsi:type="Element" name="composant">
<children xsi:type="Attribute" name="typeComposant" value="b"/>
<children xsi:type="Attribute" name="r" value="1546"/>
<children xsi:type="Attribute" name="uidComposant" value="5990"/>
</children>
</Root>......

but i want it as a model xml like this
<?xml version="1.0" encoding="ISO-8859-1"?>
<Root xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="XML" name="m">

<children xsi:type="Attribute" name="r" value="015"/>
<children xsi:type="Attribute" name="uidComposant" value="1235"/>
</children>
<children xsi:type="Element" name="composant">
<children xsi:type="Attribute" name="typeComposant" value="b"/>
<children xsi:type="Attribute" name="r" value="157"/>

<children xsi:type="Attribute" name="r" value="1546"/>
<children xsi:type="Attribute" name="uidComposant" value="5990"/>
</children>
...
</Root>

So how can i do!!

I need your help,

Have you checked your input model as I told you before?
If you obtain such an output model according to your described transformation rule (which is basically a simple "Root element copy" rule), this means that you also have the same several Root elements in your input model.

In your transformation, do you have only one rule matching elements of type Root (i.e. the one in the first post of this conversation)?
If yes, I cannot understand why ATL would create several Root elements in your output model from one Root element in your input model...

Hi

You will generally save a lot of your own time as well as other people's
time for non-obvious problems if you take the trouble to produce a
zipped project with launch configuration that demonstrates your
observations.

Hello,

The transformation you've just shown in your last post is not the same than the one shown in your original post: please, in the future, be sure to provide the right transformation when asking your questions otherwise it is not possible for the community to provide you a good answer.

Anyway, the result model you obtain is normal according to the specified transformation: you are asking for a matching on each tuple of the Cartesian product between the Root and Element elements of your input model (as you have two elements in the rule input pattern), so you get in output as much Root elements as you have of Element elements in input.

If you go back to the initial ROOT rule (cf. your first post), you will get only one Root element in your output model.
You then have to create another rule to match the Element elements, etc.

Best regards,

thank you for the response,

yes i change the code but the first one what i want.

look i cearte now an other code:
-- @path XMLC=/projetSQL/M2/XML.ecore
-- @path XMLS=/projetSQL/M2/XML.ecore

module xml2xml2;
create OUT : XMLC from IN : XMLS;

helper context XMLS!Element def: getStringAttrValue(attrName : String) : String =
let eltC : Sequence(XML!Attribute) =
self.children->select(a | a.oclIsTypeOf(XMLS!Attribute) and a.name = attrName)->asSequence()
in
if eltC->notEmpty()
then
eltC->first().value
else
''
endif;
helper context XMLS!Element def : getChildrenbyNameElement(attr:String) : Set(XMLS!Element) =
self.children->select(a | a.oclIsTypeOf(XMLS!Element) and a.name=attr)->asSequence()
;
helper context XMLS!Root def : getChildrenbyName(attr:String) : Set(XMLS!Element) =
self.children->select(a | a.oclIsTypeOf(XMLS!Element) and a.name=attr)->asSequence()
;
helper context XMLS!Element def : getchildren(a:String) : String =
let e:Sequence(XMLS!Element)=
self.getChildrenbyNameElement('C')
in
if e->notEmpty()
then
e->first().getStringAttrValue(a)
else
''
endif
;


helper context XMLS!Root def : getCN(a:String) : String =
let e:Sequence(XMLS!Element)=
self.getChildrenbyName('N')->asSequence()
in
if e->notEmpty()
then
e->first().getchildren(a)
else
''
endif
;

--rule Root--
rule Root {
from
i: XMLS!Root
to
o : XMLC!Root (
name <- i.name,
children <- Sequence{comp}
),
comp:XMLC!Element(
name <- 'Composant',
children <- Sequence{tyComp}
),
tyComp:XMLC!Attribute(
name <- i.getCN('TypC')
)
}


but as a result with the same model, i get only the first instance:

<?xml version="1.0" encoding="ISO-8859-1"?>
<Root xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="XML" name="x">
<children xsi:type="Element" name="Composant">
<children xsi:type="Attribute" name="4"/>
</children>
</Root>
Thank you,

Samar.

Hello,

As I already said in my previous post:
If you go back to the initial ROOT rule (cf. your first post), you will get only one Root element in your output model.
You then have to create another rule to match the Element elements, etc.


So you should have a dedicated rule to deal with Element elements, another rule to deal with the Attribute elements, etc. The overall structure of your transformation should look like the following (please read carefully the ATL user guide that explains everything with a lot of details):
rule RootToRoot {
from
i: XMLS!Root
to 
o : XMLC!Root (
name <- i.name,
children <- i.children->union(Sequence{comp})
),
comp:XMLC!Element(
name <- 'Composant',
children <- Sequence{tyComp}
),
tyComp:XMLC!Attribute(
name <- i.getCN('TypC')
)
}

rule ElementToElement {
from
i: XMLS!Element
to 
o : XMLC!Element (
...
...
...
)
}

rule Attribute2Attribute {
from
i: XMLS!Attribute
to 
o : XMLC!Attribute (
...
...
...
)
}

Etc.

If you look to the XML metamodel you are using, I guess you will see that Root is inheriting from Element (which means that a Root element is also an Element element, that could be why you have your error).
Thus, in your ElementToElement rule, you have to add a filter to avoid such a Root element to be matched twice (i.e. also by the RootToRoot rule):
rule ElementToElement {
from
i: XMLS!Element (
 not i.oclIsTypeOf(XMLS!Root)
)
