Insert Text After Specific XML Tag in Nokogiri

问题

I'd like to create the following XML:

<?xml version="1.0">
<foo>
  <bar/>
  TEXT GOES HERE
</foo>

The structure is pretty simple to build with Nokogiri:

builder = Nokogiri::XML::Builder.new do |xml|
  xml.foo { 
    xml.bar {}
  }
end
puts builder.to_xml

What I can't figure out is how to insert the TEXT GOES HERE string inside <foo> but after <bar/>.

Obviously, xml.foo("TEXT GOES HERE") produces the text before <bar>. What am I missing?

回答1:

You want the text method:

require 'nokogiri'
builder = Nokogiri::XML::Builder.new do |xml|
  xml.foo { 
    xml.bar
    xml.text "TEXT GOES HERE"
  }
end

puts builder.doc
#=> <?xml version="1.0"?>
#=> <foo><bar/>TEXT GOES HERE</foo>
