Parsing XML file using chlikat in ruby

[braj1999]

I am working on RHEL 5. I have to build a web automation framwork using
Ruby. when I am trying to read a XML file using Chilkat ruby I am
getting following error.

Ruby code where I am getting the error.

require 'rubygems'
require 'Chilkat'

...

...

xml = Chilkat::CkXml.new()
xml.LoadXmlFile('/root/Desktop/XML/Vendor_Registration_Flow01.xml')
@strContent = Chilkat::CkString.new()
@strTag = Chilkat::CkString.new()
@strXml = Chilkat::CkString.new()
@processNode = xml.SearchForTag(nil,"t:test_case")

...

....

While running the code I am getting this message --

/root/Desktop/readxml.rb:14:in `LoadXmlFile': Expected argument 0 of
type CkXml *, but got Chilkat::CkXml #<Chilkat::CkXml:0x000000038e3...
(TypeError)
in SWIG method 'LoadXmlFile'
from /root/Desktop/readxml.rb:14:in `<main>'

Please help me in resolving the error.

Thanks.
