Subject: [ANN] xml-map

Hello.

Thanks to my bas from softwarelab.eu (little advert)
I'm starting to release code that i wrote so far :)
for now there's little - or no- documentation but i'll be working on it

back to the topic:

xml-map is easy to use XML to ruby object library with rails-like models, 
validators and more ^^, it uses vary fast libxml instead of slow and old 
REXML, you need version 0.4 of libxml to work properly

you can grab it from svn from xml-map.rubyforge.org

What is done:
- Import valid XML 
- autogenerate models
- some validators

what i'm working on:
- all validators from XmlSchema
- autogenerating models with validators from xsd

require 'rubygems'
require 'xml/libxml'

require '../lib/xml_models'

require 'pp'

============================================
> cat sample/sample.rb

tfile = ARGV.shift || "test.xml"
# auogenerate required models
xm=XmlMapper.new({:generate=>true, :file=> $stdout})

#load xml file
doc = XML::Document.file(tfile)
root_node = doc.root

# parase xml and create model instances
rn = xm.parse_xml(root_node)

pp rn

rn.content[0].content<<"dwa"

rn.save(out.xml)

============================================
> cat sample/test.xml
<?xml version="1.0"?>
<root>
  <simple>raz</simple>
  <Complicated param2="2" param1="string" param3="3">
    <simple>dwa</simple>
    <simple>trzy</simple>
  </Complicated>
</root>
============================================
ruby sample.rb
class RootNode < XmlNode
 end

class SimpleNode < XmlNode
 end

class ComplicatedNode < XmlNode
 end

#===== class generation ends here, you can copy above classes add 
attr_accessors for desired attributes

#<RootNode:0xb7810364
 @content=
  [#<SimpleNode:0xb780fc20 @content=["raz"], @node_name="simple">,
   #<ComplicatedNode:0xb780f39c
    @content=
     [#<SimpleNode:0xb780eac8 @content=["dwa"], @node_name="simple">,
      #<SimpleNode:0xb780e640 @content=["trzy"], @node_name="simple">],
    @node_name="Complicated",
    @param1="string",
    @param2="2",
    @param3="3">],
 @node_name="root">

======================================

soon i'm going to provide more documentation and more compleate support for 
xsd and validators, if anyone is interested in helping in this easy but time 
consuming work, please let me know ^^
