我不确定这是 REXML 还是 ruby 问题。但是当我使用 REXML 时,就会发生这种情况。
下面的程序应该访问目录中每个 xml 文件的元素。
#!/usr/bin/ruby -w
require 'rexml/document'
include REXML
p "Current directory was: " + Dir.pwd
Dir.chdir("/home/askar/xml_files1") {
p "Now we're in: " + Dir.pwd
if File.exist?(Dir.pwd)
xml_files = Dir.glob("ShipmentRequest*.xml")
Dir.foreach(Dir.pwd) do |file|
xmlfile = File.new(file)
xmldoc = Document.new(xmlfile)
end
else
puts "It's empty"
end
}
当我运行时:
ruby import_xml.rb
错误:
"Current directory was: /home/askar/Dropbox/rails_studio/xml_to_mysql"
"Now we're in: /home/askar/xml_files1"
There're 6226 files in the folder...

当我注释掉:
#xmldoc = Document.new(xmlfile)
它没有给出错误。
文件夹 /home/askar/xml_files1 仅包含 3 个 xml 文件。
我正在使用 Linux Mint Nadia 和
ruby -v
ruby 1.9.3p429 (2013-05-15 revision 40747) [x86_64-linux]
如果您注意到,由于某种原因,错误显示 ruby 1.9.1。这是一个问题吗?
