这对于学习 Ruby 来说真的不是问题。数据笨拙且不可靠，对于您相对熟悉的语言来说，这将是一个有用的编程挑战。当您学习一门语言时，您需要的任务相对简单，但会测试您对语言本身的了解。
我已经写了这个，它至少符合你在章节07 中的示例。
它的工作原理是从页面中选择一个（唯一的）具有多行的表格。然后它遍历这些行，提取字段数组，将不可破坏的空格转换为普通空格，并去除前导和尾随空格。丢弃所有空字段，如果不包含数据，则忽略整行。
然后第一列以十进制数字开头的行表示章节的第一行，或者如果前面有连字符则表示同一章节的章节信息。
如果源中缺少某个字段（描述 字段和部分标题），我通常会选择从中间数据中省略它。但是，我已将这些字段默认为空字符串，以符合您的预期 JSON 输出示例。 （不存在的散列元素与值为nil 的散列元素之间存在差异。）
我希望这会有所帮助。
require 'open-uri'
require 'nokogiri'
require 'json'
open('http://www.s-techent.com/ATA100.htm') do |f|
doc = Nokogiri::HTML(f)
table = doc.at_xpath('//table[count(tr) > 1]')
chapters = []
chapter = nil
table.xpath('tr').each do |tr|
td = tr.xpath('td')
td = td.map { |td| td.content.gsub("\u00A0", ' ').strip }
td = td.select { |txt| not txt.empty? }
next if td.empty?
if td[0] =~ /^\d+/
chapters << chapter if chapter
chapter = {
'chapter' => td[0],
'title' => td[1],
'description' => td[2] || ''
}
elsif td[0] =~ /^-(\d+)/
section = {
'number' => $1,
'title' => td[1] || '',
'description' => td[2] || ''
}
chapter['section'] ||= []
chapter['section'] << section
end
end
chapters << chapter if chapter
puts JSON.pretty_generate(chapters)
end
