Hallo folks,
I am wondering if and how I can extract the Xpath of an EObject which
refers to the nodes in the XML file.
But not specific to the emf-model, which is returned by
eObj.eResource().getURIFragment(eObj);
"//@uiTemplate/@classes/@furnitureClasses/@textClasses.0" (returned by
getURIFragment)
but
"//@uiTemplate/@classes/@furniture/@text[class='furnText2']"
where the XML file is:
<uiTemplate
<classes
<furniture
<text class="furnText2" ...
...
thanks in advance
Luca

Thanks Ed,
adding ecore:keys="class" it works fine. Thank you.
Another question: is it possible to retrieve the XML-Xpath instead of the
EMF-Xpath ?
Thank you in advance

Thanks Ed,
but isnt the xml-node-name equivalent specified in the ecore file
somewhere?
My idea is to parse the eObject until root and for each element get the
corrisponding xml-node name.
I believe it is an attribute of annotation from EAttribute or EReferences...
but cant fint it :-(
thanks in advance

There's extended meta data, but not all models have that. In fact, some
models are serialized as XMI where references might be serialized as
either an element or an attribute.

You can try ExtendedMetaData.INSTANCE's APIs for getting this type of
information.

Thank you Ed,
ResourceSet resourceSet = eObj.eResource().getResourceSet();
ExtendedMetaData extendedMetaData = new
BasicExtendedMetaData(resourceSet.getPackageRegistry());
EStructuralFeature eStructuralFeature = eObj.eContainingFeature();
String name = extendedMetaData.getName(eStructuralFeature);
System.out.println(name + " " + eObj);
works well.
