Module: MultiXML::Parsers::DomParser Private

Included in:
Libxml, Nokogiri, Oga
Defined in:
lib/multi_xml/parsers/dom_parser.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

Shared DOM traversal logic for converting XML nodes to hashes

Used by Nokogiri, LibXML, and Oga parsers. Including modules must implement:

  • each_child(node) { |child| ... }
  • each_element_attr(node) { |attr| ... } (non-namespace-decl attrs only)
  • each_namespace_decl(node) { |prefix_or_nil, uri| ... }
  • element_parts(node) -> [prefix_or_nil, local_name]
  • attr_parts(attr) -> [prefix_or_nil, local_name]
