hpricot and regexp?

[Feng Tien]

I'm trying to grab the "cache date" off of the google search.

using Mechanize (and built in hpricot)


agent = WWW::Mechanize.new
agent.user_agent_alias = 'Mac Safari'
page = agent.get("http://www.google.com/")
search_form = page.forms.with.name("f").first
search_form.q = "Hello"
search_results = agent.submit(search_form)
cache_date = agent.click search_results.links.text('Cached')

date = cache_date.search('table table > td').inner_html


How do i grab the date like on this page:
http://209.85.173.104/search?q=cach...s=org.mozilla:en-US:official&client=firefox-a

the part that's right after "as retrieved on" (the date)
Is there a built in hpricot method that can search by rexep?
or will I have to use something like gsub?

oops, I mean, grep.

oh, i got it down to this:

date = cache_date.search('table table > td').inner_text.grep(/retrieved
on (.+)./)


which outputs:["This is G o o g l e's cache of http://www.hello.com/ as
retrieved on May 11, 2008 01:09:29 GMT.\n"]

How do I get rid of everything before the date?

Now I have this:

date = cache_date.search('table table > td').inner_text.grep(/retrieved
on (.+)./).to_s.gsub(/.+as retrieved on /,"").gsub(/.\n/,"")

which gives me exactly what i need. is there a better way to doing this?
