Mechanize users - Apr 2009 - undefined method ''text'' ...

Just trying to run the example

*****
  require ''rubygems''
  require ''mechanize''

  a = WWW::Mechanize.new
  a.get(''http://rubyforge.org/'') do |page|
    # Click the login link
    login_page = a.click(page.links.text(/Log In/))

    # Submit the login form
    my_page = login_page.form_with(:action =>
''/account/login.php'') do |f|
      f.form_loginname  = ARGV[0]
      f.form_pw         = ARGV[1]
    end.click_button

    my_page.links.each do |link|
      text = link.text.strip
      next unless text.length > 0
      puts text
    end
  end
*****

with command

/opt/local/bin/ruby rubyforge.rb

but getting

rubyforge.rb:7: undefined method `text'' for #<Array:0x16d2940>
(NoMethodError)
        from
/opt/local/lib/ruby/gems/1.8/gems/mechanize-0.9.2/lib/www/mechanize.rb:232:in
`get''
        from rubyforge.rb:5


Installed mechanize with

sudo /opt/local/bin/gem install mechanize

which resulted in

/opt/local/lib/ruby/gems/1.8/gems/mechanize-0.9.2/

System is Mac OS X 10.4.11

ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-darwin8]

The error message tells you line 7, which is login_page = ...

A page.links returns an Array, which -- like the error messages says-- does
not have a #text method.

You''re going to have to choose one link from the Array somehow and pass
that
to a.click().

You probably want something like:

  login_page = a.click(page.links.select{|x| x.text =~ /Log In/}.first)

Personally I would not chain all that stuff together without making sure my
#select and #first return a non-empty, non-null value. But to each his own.
