Subject: Re: edit xml file.

Josh,

Thank you for that unbelievably helpful and in-depth reply. The "editing 
xml" section of Nokogiri, is helpful, and I will experiment with that.

So now that I am a little more clear I can ask better questions. Are you 
saying that in my post block, I should do something like:




#this is defined globally
$script = File.read("public/script.xml")






post "/" do
   @xml = Nokogiri::XML($script)

   # read the nokogiri tutorial to learn how to search for the
   # thing that i want to change, and modify it,
   # i don't know how to do this yet
   @xml.blah
   # assume that worked and the Nokogiri object got modified

   # Save it back to the xml file.
   # I saw something like this, looks like it may save over the
   # original xml?
   @xml.to_xml

   # now that i've changed the xml, diplay the page again
   erb :index
end


OR,

in an index_post erb file, should I be trying to change values sorta 
like this:


<% current code %>
<% animation_url 
=dialogue.search("property[name=animationUrl]").first.andand["value"]%>

<% # my additional code suggestion. change the value based on user input
   dialogue.search("property[name=animationUrl]").first.andand["value"]
   = "some new value entered by user"%>

and then somehow write this back to the xml?

Again, thanks a ton. Hope this makes sense.
