Hey.. I just installed hpricot but it acts strange..
I tried an example from
http://code.whytheluckystiff.net/hpricot/wiki/Hpr... but it
didn't work.. It just gave me "test.rb:1: parse error, unexpected
tIDENTIFIER, expecting $"...

After that i tried ruby -ropen-uri -e
'eval(open("http://balloon.hobix.com/hpr...).read)' and it launched
the script on that page without any problems..
I tried to copy that script and pasted it into my texteditor to just
try to launch it but it gave me the :

"test.rb:1: parse error, unexpected tIDENTIFIER, expecting $
puts "You may use XPath (//span[@class='entryPermalink']) or CSS
selectors (spanendlements.each { |ele| pp ele } }t? [h/I]? "ts found."

What does that mean? And why doesn't it work? I followed the steps from
:
http://hivelogic.com/articles/2005/12/01/ruby_rails_lighttpd_m...

Maybe you better show us your actual code. There are several examples
on that page.

Look at this:

require 'rubygems'
require 'hpricot'
require 'open-uri'
doc = Hpricot(open("http://qwantz....))
(doc/"p/a/img").each do |img|
puts img.attributes['class']
end

It works although it doesn't actually find and image with a 'class'
attribute.

Weird,

I'm running ruby 1.8.5 (2006-08-18) [powerpc-darwin8.7.0] with
Hpricot 0.4.43 and I just cut and pasted the above code. It still
works. I'm stumped.

Maybe. It seems to me that if it weren't installed correctly it
wouldn't work in irb either but I can't think of anything better to try.

Yeah.. re-installed it but i still get the same error..

I just pasted:

require 'rubygems'
require 'hpricot'
require 'open-uri'

doc = Hpricot(open("http://qwantz....))
(doc/"p/a/img").each do |img|
puts img.attributes['class']
end

into a file and tried to run it.. It gave me the
"hej.rb:1: parse error, unexpected tIDENTIFIER, expecting $
require 'open-uri'"

But it still works when i paste it directly into irb..

I think maybe Justin is on to something here. Could your editor be
messing up the end-of-lines? I'm using TextMate and not having any
problems.

Smells like you've got a line-endings problem.
