      • elementByID

        Element elementByID​(java.lang.String elementID)

        Removes the given Node if the node is an immediate child of this branch. If the given node is not an immediate child of this branch then the Node.detach()method should be used instead. This is a polymorphic method which will call the typesafe method for the node type such as remove(Element) or remove(Comment).
        Parameters:
        node - is the given node to be removed
        Returns:
        true if the node was removed

        true if the comment was removed

      • remove

        boolean remove​(Element element)

        Removes the given ProcessingInstruction if the node is an immediate child of this branch. If the given node is not an immediate child of this branch then the Node.detach()method should be used instead.
        Parameters:
        pi - is the processing instruction to be removed
        Returns:
        true if the processing instruction was removed

      • normalize

        void normalize()
        Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.In cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes.
        Since:
