Description

if a closure is added to the meta class it seems that the node.@attribute is not working anymore
however it is still working when we use quotes, i.e. node.'@attribute'

here is some tests that reproduce the probleme, they have to be run alone

    @Test
    public void working() throws Exception {
        //given
        def root = new XmlParser().parseText('''<node id="12">value</node>''')

        //when
        String id = root.@id;

        //then
        assertEquals("12", id);
    }
    @Test
    public void notWorking() throws Exception {
        //given
        Node.metaClass.findParent = { closure ->
            def parent = delegate.parent()
            if(parent == null){
                return null
            }
            if(closure(parent)){
                return parent
            }
            return parent.findParent(closure)
        }

        def root = new XmlParser().parseText('''<node id="12">value</node>''')

        //when
        String id = root.@id;

        //then
        assertEquals("12", id);
    }
    @Test
    public void workingOnlyWithQuotes() throws Exception {
        //given
        Node.metaClass.findParent = { closure ->
            def parent = delegate.parent()
            if(parent == null){
                return null
            }
            if(closure(parent)){
                return parent
            }
            return parent.findParent(closure)
        }

        def root = new XmlParser().parseText('''<node id="12">value</node>''')

        //when
        String id = root.'@id';

        //then
        assertEquals("12", id);
    }
