这里使用ruby里面非常实用的库 mechanize和hpricot
sudo gem install hpricot
sudo gem install mechanize

首先准备两个文件

然后呢, 打开你最习惯的代码编辑器, 使用如下代码
yobo_music.rb
require "rubygems"
require "mechanize"

agent = WWW::Mechanize.new
page = agent.get "http://www.yobo.com/s/rise?fr=2"
musics = page.search "//td.risesong"
tm = File.new("tm.html", "w+")
head = File.new("head.html", "r")
tm.syswrite head.read
head.close
musics.each do |music|
    tm.syswrite "<tr>"
    tm.syswrite music.to_html
    tm.syswrite "</tr>"
end


end_file = File.new("end.html", "r")
tm.syswrite end_file.read
end_file.close

tm.close

最后, 我未检测过是否必须登录才可以听歌, 如果确实要登录, 你可以尝试这样
yobo_login.rb
require "rubygems"
require "mechanize"

agent = WWW::Mechanize.new
page = agent.get    "http://www.yobo.com/s/rise?fr=2"
forms = page.forms
login_form = form[3]

#用户邮箱
login_form.fields[0] = "[email]xxx@xxx.com[/email]"
#密码
login_form.fields[1] = "xxxxxxxx"

#登录
page = agent.submit login_form
