我需要为一个看起来大致如下的Feed生成一个xml: –
<?xml version="1.0" encoding="iso-8859-1" ?> <RSS version="2.0" xmlns:g="http://base.google.com/ns/1.0" xmlns:atom="http://www.w3.org/2005/Atom"> <channel> <item> <g:id><![CDATA[id]]></g:id> <title><![CDATA[Product Name]]></title> <description><![CDATA[This should be a relatively detailed description with as little formatting as possible.]]></description> <g:brand>Brand X</g:brand> <g:sale_id>new</g:sale_id> </item> <item> Next product... </item> </channel> </RSS>
我的代码目前看起来像这样: –
xml=Builder::XmlMarkup.new(:indent => 3) xml.instruct! xml.RSS("version" => "2.0","xmlns:g" => "http://base.google.com/ns/1.0","xmlns:atom" => "http://www.w3.org/2005/Atom"){ xml.channel{ # remove xml.namespace = xml.namespace_definitions.find{|ns|ns.prefix=="atom"} sale_products.each do |sp| sid = (products_info[sp.product_id]["sale_id"]).to_s() xml.item { #xml.id{ |xml| xml.cdata!(products_info[sp.product_id].own_id) } #xml.g :id,{ xml.cdata!("sdaf") } xml.product_title{ |xml| xml.cdata!(products_info[sp.product_id].name) } xml.description{ |xml| xml.cdata!(ActionController::Base.helpers.strip_tags(products_info[sp.product_id].description)) } xml.item { xml.brand { |xml| xml.cdata!(products_info[sp.product_id].designer_1) } xml.sale_id{ |xml| xml.cdata!(sid) } } } end } }
xml.g :id,"fdsafsad"
这将获取namesapce前缀.
xml.product_title{ |xml| xml.cdata!(products_info[sp.product_id].name) }
这会在值周围获得cdata标记.
xml.g :id,{ xml.cdata!("sdaf") }
这无法做到这一点.
如何同时为同一标记获取名称空间前缀和cdata标记.我究竟做错了什么?
编辑: – 我目前得到的输出如下: –
<g:id> <![CDATA[10005-0003]]> </g:id>
我想要的输出应该只有cdata标签内的值(没有换行符等): –
<g:id><![CDATA[10005-0003]]></g:id>
解决方法
xml.tag!("g:id") { xml.cdata!("sdaf") }
