Hi Everyone,

I’m required to write a ruby script that can edit an xml file, this
script must uncomment a block of the xml document.

jetty.xml

  </New>
</Set>

How can i remove comments for this block only?

on my ruby script i have the following code, when i run the code it
removes
all the comments and its content as well.
require ‘nokogiri’

file = File.read(“jetty.xml”)
xml = Nokogiri::XML(file)

#replace with a space
xml.xpath("//comment()").each do |node|
node.content =node.content.gsub!(/(^\D\W[<!–}]\W[–>])/,’ ')
end

File.open(“newjetty.xml”,“w”) do |f|
f.write xml.to_xml
end
