I tried to translate README into English.
It has probably some mistakes, but it is better than nothing
for non-Japanese speaker, I think.

--README----------------------------------------------------------
`xmlscan' is a collection of XML-related technology implemented Ruby.
The goal is to construct XML application with only Ruby.

It's still under construction.


xmlscan.rb:

  class XMLScanner

    Class for parsing XML document.
    It does not use any extended library, just only Ruby.

  module XMLScanner::Loose

    Mix-in which make scanner ignore any error.

  module XMLScanner::Recoverable

    Mix-in which make scanner raise ParseError and continue parsing.

  module XMLScanner::ExternalEntity

    Mix-in to parse external parsed entity.

  class LooseXMLScanner
  class RecoverableXMLScanner

    XMLScanner including {Loose|Recoverable}.

  class WellFormedXMLScanner

    XMLScanner with some well-formed contraint.

  class XMLScannerWithNamespace

    WellFormedXMLScanner with supporing XML Namespace.


htmlscan.rb:

  module XMLScanner::HTML

    Mix-in to parse HTML.

  class HTMLScanner
  class LooseHTMLScanner
  class RecoverableHTMLScanner

    XMLScanner including HTML.
    It is a little faster than html-parser/sgml-parser.rb with
    some HTML docuemnts.

xmltoken.rb:

  module XMLScanner::Tokenizer

    pull-based XMLScanner(?). Under construction.


xmldtd.ry:

  class XMLDTDScanner

    class for parsing DTD. You need Racc. Under construction.


xpath.ry:

  module XPath

    XPath processor for Ruby.

  class XPath::Compiler

    class for compiling XPath expression into Ruby script. you need Racc.

xpath.rb:

  racc -E -o xpath.rb xpath.ry


xpathtree.rb:

  Sample implementation of XPath data model. It's just sample.

xpath-dom.rb:

  XPath supporting DOM. It uses Adapter pattern to separate
  processing module and data structure, but it is too slow (;_;
  It might be rejected.


You can redistribute/modify it under the same term as Ruby.
