的Ruby/Rails - Scrapi宝石问题抓下一格文本

Question

我有以下HTML：

<div class="tvShow" align="left"> 
    <div class="clearfix" style="margin:0px 0px;"> 
     <h3 class="left" style="margin:0px 0px">FIRST TUESDAY BOOK CLUB WITH JENNIFER BYRNE</h3> 
    </div> 

    <div>Thursday 22nd December at 2.00 pm (60 minutes)</div> 

    <div><b>Channel: </b>ABC1</div> 
    ... 
</div> 

我使用scrapi宝石刮内容。

这是我迄今为止提取h3：

channel_item = Scraper.define do 
    process "h3", :name => :text 
end 

# let scrapi begin 

listings = Scraper.define do 
    array :programs 
    process "div.tvShow", :programs => channel_item 
    result :programs 
end 

# loop through the listings 

listings.scrape(uri).each do |program| 
    puts program.name.titleize # h3 text 
end 

我不完全知道如何提取周四12月22日下午2点（60分钟）和通道： ABC1文本。

任何帮助，将不胜感激。提前致谢。

试试这个：

channel_item = Scraper.define do 
    process "h3", :name => :text 
    process "div[2]", :time => :text 
    process "div[3]", :channel => :text 
end
