You seem to be making great progress with Hpricot, committing changes  
every day.

Yep, 'require_gem' no longer works. Just using 'require' seems better.

I don't know that I communicated my idea behind adding a set method  
for Hpricot::Text. There are times when one wants to scan an  
potentially change everything that's *not* markup. The markup should  
be left unchanged or modified only in trivial ways such as changing  
the order of attribute declarations.

Hpricott::Traverse#traverse_text is great for finding as the stuff  
that's *not* markup, the pcdata, in an HTML file. I just added a  
method to change that data.

You suggested using inner_html= but the only way I can see that  
working is to parse the tree looking for those elements which only  
have Hpricot::Text children and then using inner_html= on them. But  
that would involve essentially recreating  
Hpricott::Traverse#traverse_text to find such elements although the  
common code could mostly be factored out.
