##
Instance Method Detail

def [](index : Int) : Node #
def each(&) : Nil #
Description copied from module Enumerable(XML::Node)

Must yield this collection's elements to the block.

def empty? : Bool #
Description copied from module Enumerable(XML::Node)

Returns `true` if `self` does not contain any element.

    ([] of Int32).empty? # => true
    ([1]).empty?         # => false
    [nil, false].empty?  # => false

- `#present?` returns the inverse.

def inspect(io : IO) : Nil #
Description copied from struct Struct

Appends this struct's name and instance variables names and values to the given IO.

    struct Point
      def initialize(@x : Int32, @y : Int32)
      end
    end

    p1 = Point.new 1, 2
    p1.to_s    # "Point(@x=1, @y=2)"
    p1.inspect # "Point(@x=1, @y=2)"

def pretty_print(pp : PrettyPrint) : Nil #
Description copied from class Object

Pretty prints `self` into the given printer.

By default appends a text that is the result of invoking `#inspect` on `self`. Subclasses should override for custom pretty printing.

def size : Int32 #
Description copied from module Enumerable(XML::Node)

Returns the number of elements in the collection.

    [1, 2, 3, 4].size # => 4

def to_s(io : IO) : Nil #
Description copied from struct Struct

Same as `#inspect(io)`.
