rexml - How to print empty node with close tag

Question

require 'rexml/document'
str = File.readlines('myxml.xml').join # '<a></a>'
el = REXML::Document.new str
p el.to_s # "<a/>"

I want <a></a> instead of <a />. How can I get this with rexml in ruby?

Show your attempt, please. – Aleksei Matiushkin Mar 15 '17 at 10:59 — Aleksei Matiushkin, Mar 15 '17 at 10:59

Since it’s an XML, the elements got collapsed unless there is a [possibly emply] node nested:

el.root.add_text ''
el.to_s
#⇒ "<a></a>"

Is there a way to keep the origin rather than modify it? Assume I am parsing an xml file, it is not applicable to inspect all nodes, right? – Mike Mar 16 '17 at 01:55
