Ok, I don't implement namespace handling yet. 

But I introduced the node types in XML::LibXML and by default I 
export them. I am aware this is not very beautyfull -- well, the 
way it's done ... 

Since most functions need more than just a simple call to libxml2
I wrapped them in dom.c. I believe this is a better way than just put
the whole code in the XS file.

Then I patched LibXML.xs and added the parts
 XML::LibXML::Node 
 XML::LibXML::Element
 XML::LibXML::Text
 XML::LibXML::Comment
 XML::LibXML::CDATASection
As well some extra functions in XML::LibXML::Document.

Common node related functions are implemented in XML::LibXML::Node, 
so only specialized functions had to be reimplemented for sublevel 
classes. 

I treat XML::LibXML::Text as the CharacterData Class from the 
DOM spec. Since libxml2 implements all character classes slightly
different, each constructor had to be implemented seperatly.

This implementation is aware about all subclasses that are supported:
The CLASS Constant is set depending on the type of the node currently 
handled. Differently to the previous implementation it does not 
coredump that much any more. ;-)

As well I added a chunk of documentation and a new example.

_VERSION_F_ (05.17.2001)

code cleanup and better documentation
"dom.h" , "dom.c" are both much smaller after I removed redundant code
"dom.c" is sorted analogue to "dom.h"

all documentation about my extensions can be found in "examples/libxml.xml"
the script "examples/xml2pod.pl" will transform this XML document into 
various .pod documents.  
better testing the encoding


_VERSION_D_

added nodelist functions 
and 
element->getElementsByTagName 


_VERSION_C_

the current version includes some securety fixes in dom.c and LibXML.xs

also a better testsuite

-- LibXML.xs_1.22

completed function setAttributeNode
added function getAttributes 
added function getAttributesNS

more node security fixes 

these functions will return an array of attribute nodes.
both will probably renamed before i make them public


idea: global encoding constant, so all user input will be encoded from
that encoding to utf8 INTERNALLY

todo: add xmlEncodeEntitiesReentrant for all text content

dom.h/dom.c

introduced domSetAttributeNode
cleaned the test suite

LibXML.xs_1.23
    + getOwner returns the Owner Node (root of the subtree)
      of the current element 
    + getOwnerDocument returns the Owner document of the node if any 
    + proxy fixes
    + introduced documentfragment
      i will allways create a document fragment for EACH unbound node.
      made the documentFragment a node 
    + more securety checks and less memory leaks...
    + better array handling
    + DOM L2 conform naming (optional)
    + entity encoding fixed

dom.c_1.21
   + domsetnodevalue is aware of attributes as well
   + domreplacenode introduced
   + added internal function insert_node_to_nodelist

t/06nodetypes.t
   + document_fragment tests 

VERSION 1.01

   + multiple parser layer (it looks like overkill but it is not!)
   + on the fly XInclude expanding while parsing
