如何使用 Nokogiri 解析 XML 并拆分节点值? [英] How do I parse XML using Nokogiri and split a node value?

问题描述

我使用 Nokogiri 来解析 XML.

I'm using Nokogiri to parse XML.

doc = Nokogiri::XML("http://www.enhancetv.com.au/tvguide/rss/melbournerss.php")

我不确定如何正确检索节点值.

I wasn't sure how to actually retrieve node values correctly.

我特别关注位于 item 下的 title、link 和 description 节点父节点.

I'm after the title, link, and description nodes in particular that sit under the item parent nodes.

<item>
    <title>Toasted TV - TEN - 07:00:00 - 21/12/2011</title>
    <link>http://www.enhancetv.com.au/tvguide/</link>
    <description>Join the team for the latest in gaming, sport, gadgets, pop culture, movies, music and other seriously fun stuff! Featuring a variety of your favourite cartoons.</description>
</item>

我想做的是 title.split("-")，这样我就可以将日期和时间字符串转换为有效的 DateTime对象稍后在轨道上使用.

What I'd like to do is title.split("-") in such a way that I can convert the date and time strings into a valid DateTime object to use later on down the track.

推荐答案

由于这是一个 RSS 提要，您可能需要考虑使用 RSS 解析器:

Since this is an RSS feed, you may want to consider an RSS parser:

require 'simple-rss'
require 'open-uri'

feed = 'http://www.enhancetv.com.au/tvguide/rss/melbournerss.php'
rss = SimpleRSS.parse open(feed)

rss.items.each do |item|
  puts item.title, item.link, item.description
end
