Finding PsiReference to an XML file referenced by an XML tag value in custom PsiReferenceContributor Follow

Hello!

I am attempting to create a custom PsiReferenceContributor which interprets the value of a tag in an XML file as a reference to another XML file. For example:

<site>
   <group-profile-ref>mygroup</group-profile-ref>
</site>

where mygroup is interpreted as a reference to an xml file that lives in the same root as the above xml file and would have a relative path of something like m/mygroup/config/config.xml

I have been able to get a VirtualFile for the mygroup config.xml file, but am having no luck getting a reference to the that file so that  "Go To Declaration" works when mygroup is clicked on.

Here is what I have so far:

public class SiteReferencesContributor
        extends PsiReferenceContributor {
    private static final VirtualFilePattern CONFIG_XML = namedXmlFile("config.xml");
    private static final XmlTagPattern.Capture SITE_TAG = xmlTag().withName("site");

    @Override
    public void registerReferenceProviders(@NotNull PsiReferenceRegistrar registrar) {
        registrar.registerReferenceProvider(psiElement(XML_DATA_CHARACTERS)
                        .withParent(xmlText()
                                .withParent(siteChildren("profile-ref", "group-profile-ref",
                                        "oem-profile-ref", "country-profile-ref"))),
                new ProfileReferenceProvider());
    }

    private static VirtualFilePattern namedXmlFile(final String name) {
        return virtualFile()
                .ofType(XmlFileType.INSTANCE)
                .withName(name);
    }

    private static PsiElementPattern<XmlTag, XmlTagPattern.Capture> siteChildren(String... names) {
        return xmlTag()
                .withName(names)
                .withParent(SITE_TAG)
                .inVirtualFile(CONFIG_XML);
    }
}

public class ProfileReferenceProvider
        extends PsiReferenceProvider {
    private static final PsiFileReferenceHelper fileReferenceHelper = new PsiFileReferenceHelper();

    @NotNull
    @Override
    public PsiReference[] getReferencesByElement(@NotNull final PsiElement element, @NotNull ProcessingContext context) {
        String profile = element.getText();
        final Project project = element.getProject();
        final VirtualFile referringFile = element.getContainingFile().getVirtualFile();
        final PsiFileSystemItem dvsRoot = fileReferenceHelper.findRoot(project, referringFile);
        final String relativeProfilePath = profile.toLowerCase().charAt(0) + "/" + profile + "/config/config.xml";
        final VirtualFile profileXml = dvsRoot.getVirtualFile().findFileByRelativePath(relativeProfilePath);
        if (profileXml != null && profileXml.exists()) {
            final PsiManager psiManager = dvsRoot.getManager();
            PsiFile file = psiManager.findFile(profileXml);
            return new PsiReference[]{file.getReference()};
        }
        return PsiReference.EMPTY_ARRAY;
    }
}

Any help would be greatly appreciated.

Thanks!
