conditions to match reference provider

Something like this should work:

xmlAttributeValue()
      .withLocalName("receiver")
      .withSuperParent(2, DomPatterns.withDom(domElement(FooBar.class)

Hi Pribluda,

Could you post your sample XML, what you're trying to match, and what your DomElement interfaces look like? :)

Could it also be that your parent DomElement is actually a SuperParent for instance?

For example, here is an example of matching the XmlAttributeValue "value" if it has a super domElement parent of a BlueprintBean

Example of matched XML :

My XML:

   <link_in type="http" trigger="blamblam" receiver="StartMEssage"/>

And automagically generated interface:

public interface Link_in extends DomElement {

 .....
     /**
      * Returns the value of the receiver child.
      * @return the value of the receiver child.
      */
     @NotNull
     GenericAttributeValue<String> getReceiver();


}
 

So I like to reference to attribute value  of this tag defined by interface.  And while we are at it,  I'd like to navigate  to some other corresponding
tag ( so I shall return proper PSI element from my reference provicder?  right?  )  and provide error if no such tag  is found.   Is PsiReferenceContributor proper tool for this?

Solved.

Proper condition was:

 xmlAttributeValue().withLocalName("receiver").withSuperParent(2,xmlTag().withLocalName("link_in").withNamespace(NAMESPACE_URI));

Depending on your DOM and @Namespace definitions there, this might differ in the future when you change one place. I'd use DomPatterns if possible to make sure any changes in DOM are reflected here.

It did not worked with DomPatterns ,  despite declared namespace on generated interface.

Did you call com.intellij.util.xml.DomFileDescription#registerNamespacePolicy in your DomFileDescription?

Namespace policy is registered.     Shall I put key of namespace policy into @Namespace annotation or uri on interface?

@Namespace takes the key which is then registered in com.intellij.util.xml.DomFileDescription#registerNamespacePolicy with the corresponding URI(s).
See com.intellij.struts2.dom.struts.Struts2DomFileDescription and com.intellij.struts2.dom.struts.StrutsRoot as example.

OK,  not I'm slowly groking my problem.   You have to assure reachability of all the elements from root elelemt
with proper @Subag annotations  - otherwise DOM does not work properlyand does not know subtag classes.

Also,  need to check generated dom classes and adjust manually
