Re: [Wtr-general] xpath support doesn't work for me

Hi Chris,

I am still not able to locate the cause of error. Lets make sure that these things are in place:

1. You should have new 'elements.rb' & 'functions.rb' copied from tar ball to [ruby installation directory]/lib/ruby/1.8/rexml. This is the correct folder where you should have elements.rb & functions.rb.

2. You have latest version of watir installed using install.rb not by using watir_installer.exe

Let me know if you still face any problem.

Regards,
Angrez

Hi Angrez,

I haven't been able to spend time on this recently. As you can see from the details below my setup should be okay

C:\>ruby -vrrexml/rexml -e 'p REXML::Version, PLATFORM'
ruby 1.8.2 (2004-12-25) [i386-mswin32]
"3.1.2.1"
"i386-mswin32"

Given the following error

c:/ruby/lib/ruby/site_ruby/1.8/watir.rb:1922:in `elements_by_xpath': undefined method `elements' for nil:NilClass (NoMethodError)
        from c:/ruby/lib/ruby/site_ruby/1.8/watir.rb:1912:in `element_by_xpath'
        from G:/workspace/web_pages/trial.rb:3

This is what's in watir.rb at line 1922

        def elements_by_xpath(xpath)
            doc = rexml_document_object()
            modifiedXpath = ""
            selectedElements = Array.new

=>        doc.elements.each(xpath) do |element|   <= line 1922
                modifiedXpath = element.xpath
                temp = element_by_absolute_xpath(modifiedXpath)
                selectedElements << temp if temp != nil
            end

element.rb seems to be the missing link. I've tried this file in several locations

C:\ruby\lib\ruby\1.8\rexml

C:\ruby\lib\ruby\1.8\watir\rexml
C:\ruby\lib\ruby\site_ruby\1.8\rexml

C:\ruby\lib\ruby\site_ruby\1.8\watir\rexml

I've read the code and see where rexml/document gets loaded. If create_rexml_document_object does its thing then how can the elements be missing?

Any ideas?

Regards

Chris

p.s.

I've just tried v 1.8.4 of Ruby and get the following

c:/ruby/lib/ruby/site_ruby/1.8/watir.rb:1755: [BUG] Segmentation fault
ruby 1.8.4 (2005-12-24) [i386-mswin32]

abnormal program termination

Hi Chris,

What version of Ruby are you running?

I am using Ruby 1.8.2 and latest watir tar ball. Also REXML version is "3.1.2.1". You can check this by using following command:

ruby -vrrexml/rexml -e 'p REXML::Version, PLATFORM'

But still I have no clue of what is going wrong?

Regards,
Angrez
