Thanks for responding, why: and thanks very much for Hpricot.

I'm a long way from completely understanding Hpricot but I did try to  
use inner_html in what I though was the correct way.

Here is a little sample program:

require 'rubygems'
require_gem 'hpricot'

doc = Hpricot(open('TestFile.html'))
body = doc.search('body')
body.each {|elmnt| elmnt.inner_html}
body.inner_html
(body/:a).inner_html = "New Link Text"
puts doc

The output is:
testHpricot.rb:6: undefined method `inner_html' for #<Hpricot::Elem: 
0x7546bc> (NoMethodError)
         from testHpricot.rb:6:in `each'
         from testHpricot.rb:6

If I comment out the body.each... line I get:

testHpricot.rb:7: undefined method `inner_html' for  
#<Hpricot::Elements:0x753d48> (NoMethodError)

If I comment out that line, I get:

testHpricot.rb:8: undefined method `inner_html=' for []:Array  
(NoMethodError)


What may be related is that the file text.rb is at:
/usr/local/lib/ruby/gems/1.8/gems/hpricot-0.3/lib/hpricot/text.rb
but it is not actually being required anywhere in Hpricot. When i  
tried to require it manually, i found that it was requiring files  
that gem didn't give me. This is all in Hpricot 0.3.

Thanks again for both your time and Hpricot.
