Has anyone been successfull using the extract\_from\_table method of  
REXML::Node  
class??

This methods is an extension added by Mechanize to REXML as I can see in  
the  
source code but I am unable to use it because it complains of private  
method  
called…

here is the code I am trying

require ‘mechanize’

agent = WWW::Mechanize.new  
page = agent.get(“[http://test.ts](http://test.ts)”)

cols = page.root.extract\_from\_table(page.root, [“col1”, “col2”])

and I get

NoMethodError: private method ‘extract\_from\_table’ called for   
…  
\</\>:REXML::Document

regards.  
Horacio

Try this:

cols = extract\_from\_table(page.root, [“col1”, “col2”])
