How to listen changes of xml attributes in xml files?

I know how to listen changes in file in general

VirtualFileManager.getInstance().addVirtualFileListener(new VirtualFileAdapter(){
  @Override
  public void beforeContentsChange(VirtualFileEvent event) {
    super.beforeContentsChange(event);
  }
});

But how to listen changes of xml tag specifically? For example

Before change:
<tag id="1"/>

After change:
<tag id="2"/>

Pseudocode:
VirtualFileManager.getInstance().addVirtualFileListener(new VirtualXmlFileAdapter(){

  @Override
  public void beforeXmlAttributeChange(String oldValue/*==1*/, String newValue/*==2*/) {
    super.beforeXmlAttributeChange(oldValue, newValue);

  }
});
