Hi all,

I want to read and use html file content using Nokogiri in my cent os-32  
bit

but it not read any html contents.

@test = Nokogiri::HTML("abc.html")  
puts "#{@test}"

but it just shows me java scripts on source page not any html contents.

please reply me if any one know about this issue.

Thanks,  
Priyank Shah

hi,

Thanks for reply but not getting solution i get only

\<!DOCTYPE html public \"-//W3C DTD HTML 4.0 Tansitional//EN\" .....

as a output, not actual html contents in file.

I check nokogiri but i think it is some html character set encoding  
issue.

can you give me some idea about this?

Thanks,  
Priyank Shah

What Ryan is telling you: you have to pass a filepointer or the actual HTML as string, not a string containing a filename.

Can't reproduce your problem. Try this:

&nbsp;&nbsp;require 'rubygems'  
&nbsp;&nbsp;require 'nokogiri'  
&nbsp;&nbsp;# make sure the file contains sth.  
&nbsp;&nbsp;File.open('test.html', 'w') {|f|  
&nbsp;&nbsp;&nbsp;&nbsp;f.write("\<html\>\<body\>\<h1\>Foo\</h1\>\</body\>\</html\>") }

&nbsp;&nbsp;f = File.open('test.html')  
&nbsp;&nbsp;data = Nokogiri::HTML(f)  
&nbsp;&nbsp;puts data  
&nbsp;&nbsp;p data

Hi,

First thanks to all for helping me in my problem.

I got the solution finally,

I tried

f = open("test.html").read  
data = Nokogiri::HTML(f)  
puts data  
instead of

f = FIle.open("test.html")  
data = Nokogiri::HTML(f)  
puts data

and i get html data.

so basically i don't use File class.

Thanks,  
Priyank Shah
