Xml-map

Ruby
1

Hello.

Thanks to my bas from softwarelab.eu (little advert)
I’m starting to release code that i wrote so far :slight_smile:
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"?> raz dwa trzy ============================================ 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 ^^

two more things:

  • this module was tested on nearly 20mb XML file and worked fine, it
    made
    syncing between database and xml piece of cake (i’m going to relase code
    that
    made comparing between AR models and XmlModels so easy)

  • it was NOT tested on strange xmls - so PLEASE send me everything you
    got,
    strange xml’s with CDATA, strange characters encodings etc if it’s not
    parased properly by this library

I am looking forward to this. I had just been looking at doing a project
which could use AR <-> xml.

Thanks for releasing!

Cheers,
Mark
