open xml file with nokogiri update node and save

Question

I\'m trying to figure out how to open an xml file, search by an id, replace a value in the node and then resave the document.

my xml

Answer 1

First of all, your node_update is actually a NodeSet, not the Node that you probably think it is. You need a Node if you want to call inner_html= on it:

node_update[0].inner_html = 'true'

Then writing out the updated XML is just a bit of standard file manipulating combined with a to_xml call:

File.open('whatever.xml', 'w') { |f| f.print(doc.to_xml) }

As an aside, your input isn't valid XML. You have a </details> but no <details>.
