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>
我正在使用scrapi
宝石来抓取内容。
这是我到目前为止提取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
我不完全确定如何提取 12月22日星期四下午2点(60分钟)和频道:ABC1 文字。
任何帮助将不胜感激。提前谢谢。
答案 0 :(得分:1)
试试这个:
channel_item = Scraper.define do
process "h3", :name => :text
process "div[2]", :time => :text
process "div[3]", :channel => :text
end
