我不確定這是REXML還是ruby問題。 但是,當我使用REXML時發生這種情況。與REXML相關的錯誤
下面的程序應該訪問目錄中每個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
}
當我運行:
ruby import_xml.rb
錯誤:
"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...

當我註釋掉:
#xmldoc = Document.new(xmlfile)
它不給錯誤。
Folder/home/askar/xml_files1只包含3個xml文件。
我使用Linux Mint的納迪亞和
ruby -v
ruby 1.9.3p429 (2013-05-15 revision 40747) [x86_64-linux]
如果你注意到了,出於某種原因,錯誤顯示1.9.1。這是一個問題嗎?
你爲什麼要使用REXML?就XML解析器而言,它已經走到了盡頭。我強烈推薦使用[Nokogiri](http://nokogiri.org)。它速度更快,功能更全面。 Tinman, –
,謝謝你寶貴的建議。我必須查看它! :) – Askar
