如何在 Ruby 中的 Nokogiri 中遍历 XML 中的项目? [英] How do I loop through items in XML in Nokogiri in Ruby?

问题描述

鉴于我有来自这个地址的 XML ，我将如何遍历 search/events/event 事件?我的意思是循环遍历 event 项目并将它们的详细信息打印到屏幕上?到目前为止，我有以下代码:

Given I have XML from this address, how would I loop through the search/events/event events? What I mean is loop through the event items and print their details to the screen? So far I have the following code:

get_xml('/events/search', :location => 'London, United Kingdom', :date => 'Today').at('events')

get_xml 是从上面的链接中获取 XML 并选择 events 节点的方法.我将如何遍历 events 节点中的项目?

get_xml being the method which takes the XML from the link above and selects the events node. How would I loop though the items in that events node?

推荐答案

你能试试这个吗

require 'rubygems'
require 'net/http'
require 'rexml/document'

# Web search for
url = 'http://api.eventful.com/rest/events/search?app_key=PbFVZfjTXJQWrnJp&location=London&date=Today'

# get the XML data as a string
xml_data = Net::HTTP.get_response(URI.parse(url)).body

# extract event information
doc = REXML::Document.new(xml_data)
doc.elements.each('search/events/event/title') do |ele|
   titles = ele.text
   p titles
end

输出:

C:\Users\vinothini\Desktop>ruby sample_nokogiri.rb

"The 39 Steps"
"Wotever Sex 6 August"
"Phoenix Fringe"
"The Lion King"
