This Ruby code uses a unified XML format to create a password record on a web server. It's intended to be run as a batch file which gets called from another Ruby application called maintain_projectx which gets called from a cronjob.

In this example the password is stored on the server not for authentication but simply to provide a reminder service in the event the user forgets it.

require 'net/http'
require 'rexml/document'
include REXML

class ProjectXClient
  attr :doc
  def initialize(raw_url)
    url = URI.escape(raw_url)
    xml_data = Net::HTTP.get_response(URI.parse(url)).body
    @doc = Document.new(xml_data)
  end
  
end

if __FILE__ == $0

  xml_project = <<PROJECT
  <project name='password'>
    <method name='create'>
      <params>
        <param var='password' val='p6789c'/>
        <param var='title' val='hotmail'/>
      </params>
    </method>
  </project>
PROJECT
  
  pxc = ProjectXClient.new("http://yourdomain.com/p/projectx.cgi?xml_project=" + xml_project)
  doc = pxc.doc
  puts doc
    
end

output -what's returned from the server is an XML response containing a result. The result echos the method executed and the output from that method, which in this instance is the xml record node 'entry'.

<result method='rtn_create'>
  <append id='19367'>
    <entry id='19367'>
      <password>p6789c</password>
      <title>hotmail</title>
      <description/>
    </entry>
  </append>
</result>

This Ruby code uses WWW:mechanize to act like a web browser.

 require 'rubygems'
 require 'mechanize'

 agent = WWW::Mechanize.new
 page = agent.get('http://google.com/')

Refer to the documentation at http://mechanize.rubyforge.org/mechanize/. Then gem install mechanize, and try running the code in an irb session.

output (extract):

=> #<WWW::Mechanize::Page

// description of your code here
This code reads an xml file, modifys an element and saves the file locally.

require 'net/http'
require 'rexml/document'

url = 'http://www.example.com/journal080907.xml'

element_name = ARGV[0] # basic_category
xpath = ARGV[1] # eg.'entries/entry'
file = ARGV[2] # eg. 'journal080907.xml'
element_value = ARGV[3] # 'ruby'

file = File.new(file,'w')
# get the XML data as a string
xml_data = Net::HTTP.get_response(URI.parse(url)).body

# extract event information
doc = REXML::Document.new(xml_data)
docx = doc

node = docx.elements[xpath]
element = node.elements[element_name]
puts element.text
element.text = 'ruby'
file.puts docx
