    - #### FilteredNodeChildren

          public FilteredNodeChildren(GPathResult parent,
                              Closure closure,
                              Map<String,String> namespaceTagHints)

      Parameters:
        `parent` - the GPathResult prior to the application of the expression creating this GPathResult
        `closure` - the Closure to use to filter the nodes
        `namespaceTagHints` - the known tag to namespace mappings

  - ### Method Detail

    - #### pop

          public GPathResult pop()

      Description copied from class: `GPathResult`
      Returns the parent of this GPathResult. If this GPathResult has no parent the GPathResult itself is returned. This is no navigation in the XML tree. It is backtracking on the GPath expression chain. It is the behavior of parent() prior to 2.2.0. Backtracking on '..' actually goes down one level in the tree again. find() and findAll() are popped along with the level they have been applied to.
      Overrides:
        `pop` in class `GPathResult`
      Returns:
        the parent or `this`

    - #### nodeIterator

          public Iterator nodeIterator()

      Overrides:
        `nodeIterator` in class `NodeChildren`
