- ## Method Details

  - ### at

    Node at(String path)
    Returns a single node located by path given as a string argument.

    If no node or more than one node is available at the specified position, `NodeNotFoundException` is thrown.

    The path is a concatenation of path elements described below.

    ## Path examples:

          node.at(":'house'/'kitchen'/~chairs/~2")
             - take global node with text 'house',
             - in its subtree node find with text 'kitchen'
             - find its child node with alias 'chairs'
             - return the second child node of the chairs

          node.at(".. 'house'/**/~dog")
              -- return node with alias 'dog' within subtree of ancestor node with text 'house'

    Following path elements are defined:

    ## Child node:

         'node text' or /"node text" : child node with text 'node text'
         'node...' : child node containing text starting with 'node'
         * or '...' : any child node
         ~1 : child node at position 1 ( any number starting with 1 is allowed)
         ~nodeAlias : child node with alias 'nodeAlias', node alias can not be a number
         because numbers are reserved for the previous selector.

    ## Descendant node:

         /**/

    ## Parent node:

         ..

    ## Ancestor node:

         ..'node text' or "node text" : the closest ancestor node with text 'node text'
         ..'node...' : the closest ancestor node containing text starting with 'node'
         ..~2  : second ancestor node also the parent node of the parent node (any positive number is allowed)
         ..~nodeAlias : the closest ancestor node with alias 'nodeAlias', node alias can not be a number

    ## Root node

    Prefix `/` as the first path character means the path starts from the root node.

         /'node text' or /"node text" : child node of the root with text 'node text'
         /'node...' : child node of the root containing text starting with 'node'
         /~nodeAlias : child node of the root with alias 'nodeAlias', node alias can not be a number

    ## Global node

    (allowed only as the first path element). Here global node is a node carrying global flag which can be set using menu or by script.

         :'node text' or :"node text" : global node with text 'node text'
         :'node...' : global node containing text starting with 'node'
         :~nodeAlias : global node with alias 'nodeAlias', node alias can not be a number

    Since:
      1.7.1

  - ### allAt

    List<? extends Node> allAt(String path)
    Returns a list of all nodes matching given path. It can contain arbitrary node number or be empty. Path syntax is described in the `at` method.
    Since:
      1.7.1

  - ### getAttributes

    Attributes getAttributes()

  - ### getAt

    Convertible getAt(String attributeName)
    allows to access attribute values like array elements. Note that the returned type is a `Convertible`, not a String. Nevertheless it behaves like a String in almost all respects, that is, in Groovy scripts it understands all String methods like lenght(), matches() etc.

           // standard way
           node.attributes.set("attribute name", "12")
           // implicitely use getAt()
           def val = node["attribute name"]
           // use all conversions that Convertible provides (num, date, string, ...)
           assert val.num == new Long(12)
           // or use it just like a string
           assert val.startsWith("1")
           // check for availability of an attribute this way:
           if (node["unknown attribute"])
              // surprise: the node has an attribute with key "unknown attribute"

  - ### find

    List<? extends Node> find(NodeCondition condition)
    Starting from this node, recursively searches for nodes for which `closure.call(node)` returns true. See `ControllerRO.find(NodeCondition)` for details.

  - ### find

    List<? extends Node> find(boolean withAncestors, boolean withDescendants, NodeCondition condition)
    Starting from this node, recursively searches for nodes for which `condition.check(node)` returns true and adds their ancestor or descendant nodes if required.
    Since:
      1.7.4 See `ControllerRO.find(NodeCondition)` for details.

  - ### findAll

    List<? extends Node> findAll()
    Returns all nodes of the branch that starts with this node in breadth-first order. See `ControllerRO.findAll()` for map-global searches.
    Since:

  - ### findAllDepthFirst

    List<? extends Node> findAllDepthFirst()
    Returns all nodes of the branch that starts with this node in depth-first order. See `ControllerRO.findAllDepthFirst()` for map-global searches.
