Adjusting AttributeValue content of an Reference in XML


I'm trying to implement XML DOM converter, however it is not clear to me how I can modify the String value of an attribute value before and after the resolution happens.


I have an XML file called MyItem.xml that contains a reference to the file itself via the name AttributeValue. However the name should be without the xml extension.

<item name="MyItem"/>


I've created DOM model

@Convert(value = MyFileReferenceConverter.class)
GenericAttributeValue<XmlFile> getName();

and a custom converter that adds the necessary extension.

public class MyFileReferenceConverter extends PathReferenceConverter {

public PsiReference[] createReferences(final GenericDomValue genericDomValue, final PsiElement element, final ConvertContext context) {
String text = ((XmlAttributeValue) element).getValue() + ".xml";
FileReferenceSet referenceSet = new FileReferenceSet(text, element, 1, null, true);
return new PsiReference[]{referenceSet.getLastReference()};



This seems to work nicely, however when I rename the file to e.g. OtherItem.xml, the contents becomes

<item name="OtherItem.xml"/>

Is there a way to remove the suffix when the file is renamed?


I was also confused by the fact that the fromString/toString methods in PathReferenceConverter were never called by anyone, but maybe that's only when used directly from my own plugin?

Create plain com.intellij.util.xml.CustomReferenceConverter returning above FileReferenceSet but with custom FileReference created via com.intellij.psi.impl.source.resolve.reference.impl.providers.FileReferenceSet#createFileReference overriding FileReference#handleElementRename to strip extension
