ruby如何生成xml文件

[phpkunpeng]

ruby如何生成xml文件，初学　用的是ruby　on　rails　　是不是直接用rails就可以生成，还是类似php写each可以形成xml？

[phpkunpeng]

谢谢楼上的两位 不过我还是有些不太懂
我用的是rails 用里面的generator先生成一个controller吗?
您能把具体步骤说一下不?

和
用ruby生成XML有什么关系?

你想用xml来配controller？像struts那样还是什么意思?

[phpkunpeng]

不太懂楼上的意思,你说的用ruby生成xml是什么?

[phpkunpeng]

怎么生成?脱离rails了吗?
我现在在rails里有个工程

[nonocast]

use REXML lib

something like

require ' rexml/document'
doc = REXML::Document.new

root = REXML::Element.new(' my-root' )
doc.add_element(root)
puts doc.to_s

具体参看他的help

顶一下.

[nonocast]

MFC能脱离C++吗?
Struts能脱离Java吗?
有点小晕

抱歉 我描述一遍
我用的是ruby on rails 我想读数据库生成一个xml文件
第一次用的是生成rhtml 我的步骤是先生成一个controller,和views.现在是想要xml不会了

[gigix]

well...at least you can generate xml with REXML, just like nonocast said. however rails provided another powerful approach building xml documents: rxml templates. please refer to section 17.2 of the book "Agile Web Development with Rails" for detailed discussion.

[phpkunpeng]

我用的是ror,第一步怎么做?
先生成controller?

[gigix]

what do you want to do? or in other words, what do you want to ask? do you want to know how to create an application with rails? or, as the title of your post suggests, do you want to know how to manipulate xml files with ruby? would you please do us a favor, tell your requirement clearly?

我觉得rails对XML的支持并不是很好,不如自己读写文件
File.open( fpath, "w" ) do |f|
f<< xml

1. generating xml documents
and
2. accessing file
are separated things...

使用rxml模版
比如你在controller查询出结果赋给变量@orders,循环输出xml文件

xml.order_list(:for_product => @product.title) do
@orders.each{|o|
xml.order do
xml.name(o.name)
xml.email(o.email)
end}
end
