ruby - 如何在 Nokogiri 中创建 ... 节点？

Question

我需要形成这样的 xml:

<jobs>
  <job>
    <title><![CDATA[cleaner]]></title>
    <description><![CDATA[cleaner in af]]></description>
    <text><![CDATA[cleaner weekly in af]]></text>
    <referencenumber><![CDATA[518]]></referencenumber>
    <company><![CDATA[we q.]]></company>
    <country_code><![CDATA[NL]]></country_code>
    <city><![CDATA[af]]></city>
    <url><![CDATA[url]]></url>
  </job>
</jobs>

builder = Nokogiri::XML::Builder.new(:encoding => 'UTF-8') do |xml|
      xml.jobs {
        data.each do |data|
          xml.job {
            xml.title {
              xml.cdata "..."
            }
            xml.text {
              xml.cdata "..."
        }
    end
   }
 end

以上不工作因为text是构建器上的现有方法。

如何创建 <text>...</text>节点？

Answer 1

来自docs :

The builder works by taking advantage of method_missing. Unfortunately some methods are defined in ruby that are difficult or dangerous to remove. You may want to create tags with the name “type”, “class”, and “id” for example. In that case, you can use an underscore to disambiguate your tag name from the method call.

附加下划线也适用于“文本”，即使用 text_ 代替:

builder = Nokogiri::XML::Builder.new(:encoding => 'UTF-8') do |xml|
  xml.job {
    xml.text_ {
      xml.cdata 'foo bar baz'
    }
  }
end

puts builder.to_xml

输出:

<?xml version="1.0" encoding="UTF-8"?>
<job>
  <text><![CDATA[foo bar baz]]></text>
</job>
