Question

在使用Nokogiri阅读器解析XML文件时，我是新手。这是我要解析的XML文件和示例代码：

<?xml version='1.0' encoding='UTF-8'?>
<inventory>
  <tire name="super slick racing tire" />
  <tire name="all weather tire" />
</inventory>
-----------------------------------------------------------------
require 'rubygems'
require 'nokogiri'

io = File.open('test.xml', 'r')
reader = Nokogiri::XML::Reader(io)

reader.each do |node|

# node is an instance of Nokogiri::XML::Readerruby
puts node.name

end

以下是我收到的错误消息：

pcs$ ruby1.9 TestNok.rb

非常感谢任何帮助。

Answer 1

您粘贴的代码在我的计算机上运行：

jablan@jablan-hp:~/dev$ ruby testxml.rb 
inventory
#text
tire
#text
tire
#text
inventory
jablan@jablan-hp:~/dev$ ruby -v
ruby 1.9.1p243 (2009-07-16 revision 24175) [i686-linux]
jablan@jablan-hp:~/dev$ gem list | grep nokogiri
nokogiri (1.4.0)

Answer 2

似乎是读者解析器的重复数据。

inventory
tire
tire
inventory

必须是：

inventory
tire

使用'Reader'和Nokogiri解析XML文档会返回LibXML错误
