Constructor Details

#initialize(name, _line_or_content = nil, _col_or_children = nil) ⇒ Element

operates in two modes:

  • from Ruby

  • from file

in file mode, args provide Element’s line and column location then freezes each Fixnum so it cannot be overwritten in Ruby mode, args are some combination of new attributes/values and/or child nodes (text or XML) with which to initialize this node

Parameters:

  • name (String) —

    name of element, in both Ruby and file modes

  • _line_or_content (Fixnum, Array, Hash) (defaults to: nil) —

    line number of element file mode; if Array, new child nodes; if Hash, attributes; can be nil

  • _col_or_children (Fixnum, Array) (defaults to: nil) —

    column position in file mode; if Array, new child nodes; can be nil
