htmlcxx - html and css APIs for C++

---------------------------------------------


	Description
	===========

htmlcxx is a simple non-validating css1 and html parser for C++.
Although there are several other html parsers available, htmlcxx has some
characteristics that make it unique:

- STL like navigation of DOM tree, using excelent's tree.hh library from
  Kasper Peeters 
- It is possible to reproduce exactly, character by character, the
  original document from the parse tree
- Bundled css parser
- Optional parsing of attributes	
- C++ code that looks like C++ (not so true anymore)
- Offsets of tags/elements in the original document are stored in the
  nodes of the DOM tree

The parsing politics of htmlcxx were created trying to mimic mozilla
firefox (http://www.mozilla.org) behavior. So you should expect parse
trees similar to those create by firefox. However, differently from firefox,
htmlcxx does not insert non-existent stuff in your html. Therefore, serializing
the DOM tree gives exactly the same bytes contained in the original HTML
document.


        News for version 0.85
        =====================

Fixed gcc 4.3 compiler errors, several minor bug fixes, improved distribution
of the css library.


	News for version 0.7.3
	======================

Added utility code to escape/decode urls as defined by RFC 2396.
Added new SAX interface. The API was slightly broken to support the new
SAX interface :-(.
Added Visual Studio 2003 projects for the WIN32 port.


	Examples
	========

Using htmlcxx is quite simple. Take a look
at this example.

-----------------------------------------------------------------------

  #include <htmlcxx/html/ParserDom.h>
  ...
  using namespace std;
  using namespace htmlcxx;
  
  //Parse some html code
  string html = "<html><body>hey</body></html>";
  HTML::ParserDom parser;
  tree<HTML::Node> dom = parser.parseTree(html);
  
  //Print whole DOM tree
  cout << dom << endl;
  
  //Dump all links in the tree
  tree<HTML::Node>::iterator it = dom.begin();
  tree<HTML::Node>::iterator end = dom.end();
  for (; it != end; ++it)
  {
     if (strcasecmp(it->tagName().c_str(), "A") == 0)
     {
       it->parseAttributes();
       cout << it->attribute("href").second << endl;
     }
  }
  
  //Dump all text of the document
  it = dom.begin();
  end = dom.end();
  for (; it != end; ++it)
  {
    if ((!it->isTag()) && (!it->isComment()))
    {
      cout << it->text();
    }
  }
  cout << endl;

	The htmlcxx application
	=======================

htmlcxx is the name of both the library and the utility
application that comes with this package. Although the 
htmlcxx (the application) is mostly useless for programming, you can use it 
to easily see how htmlcxx (the library) would parse your html code.
Just install and try htmlcxx -h.
