I use the Watir extension to generate automated test
for web pages. To control the test results I retrieve
information from the same web page, but I get the
information from a XML-file.
I use the REXML extension, and when the XML file is
saved on my computer I can retrieve the values from it
using XPath.
How can I get the values from the XML-file, so that I
can compare it with the value I set?
Code:
require 'watir'
require 'rexml/document'
include REXML
ie = Watir::IE.start("http://x.x.x.x/site.ssi")
# ie.show_all_objects
# change one value in the dropdown list
ie.select_list(:name,
"/Configuration/Audio/Inputs/Headset/Level").select_value("7")
puts "Value changed"
#saves
ie.link(:id, "").fire_event("onclick")
# open another browser and get's the xml-file
ie2 =
Watir::IE.start("http://10.47.11.217/getxml?location=/Configuration/Audio/Outputs/Headset/Level")
doc = ie2.document()
#try to use XPath to retrieve the value
node =XPath.first( doc,
"*/Configuration/Audio/Outputs/Headset/Level").get_text.value
The last line gives an error in the xpath_parser
(method_missing)
Hope someone can help me

What sort of object are you expecting ie2.document() to return?
The call to XPath.first expects a REXML Document object; the WATIR docs really don't say much on this (it only says that document() returns the current document. )
But grepping the WATIR source code does not show any references to REXML, so it appears you'll need to first convert the IE document or content to a REXML Document object.
Calling ie2.html gets you the DOM rendering of the document HTML; it's *not* the same as the HTML sent to the browser. If it is not already XML (and imagine it is not) you'll need to fix it up. Take a look at Michael Neumann's Mechanize library for some ways to do this. His code fetches HTML pages and exposes the content via a nice API over an REXML document.

Hi
I looked at this project, but I can't seem to find the
examples/code that can help me...
Can anyone tell me how to fetch the HTML code and
convert it into a REXML document?

The project is Mechanize (though it is listed on the same main page as the Wee project; really should get its own page, Michael!).
You can install Mechanize using rubygems.
This example logs into rubyforge.org, using values passed at the command line:
require 'mechanize'
agent = WWW::Mechanize.new {|a| a.log = Logger.new(STDERR) }
page = agent.get('http://rubyforge.org/'\)
link = page.links.find {|l| l.node.text =~ /Log In/ }
page = agent.click(link)
form = page.forms[1]
form.fields.find {|f| f.name == 'form_loginname'}.value = ARGV[0]
form.fields.find {|f| f.name == 'form_pw'}.value = ARGV[1]
page = agent.submit(form, form.buttons.first)
puts page.root.class
img_alt = REXML::XPath.first( page.root, "//img" ).attributes[ 'alt' ]
p img_alt
The 'root' method of the Page instance returns a REXML Document.
