REXML and Empty-Elements


#1

Hello all,

I have been using REXML to help me merge some XML files. I noticed that
simply opening an XML document and writing it to a file will
automatically convert the blank nodes with a start-tag and an end-tag to
empty-element tags. Here is an example:

Original.xml:

John
123 Maple Lane

Chicago
IL

Basic Ruby Script:
require ‘rexml/document’
xml = REXML::Document.new(File.open(“Original.xml”))
f = File.new(“New.xml”,“w”)
f.puts xml

New.xml:

John
123 Maple Lane

Chicago
IL

In this example I would like to prevent Address2 from being modified to
use empty-element tags. I would rather it be displayed as
. Is there a way to prevent REXML from converting
blank nodes?

Thank you for your time.

Ryan

Better use the block form of File.open here.

There is no point in doing this since both representations are
equivalent from an XML point of view. I don’t believe there is such a
mechanism. What does REXML’s documentation say?
