REXML adds white space to text property when indent > -1
Bug #10864: REXML adds white space to text property when indent > -1
Description
The following example shows that REXML is adding white space to the text property of elements when setting the :indent option on Document#write greater than -1. The value written should be the same value read.
require 'rexml/document' xml_string = '' REXML::Document.new(xml_string).tap do |doc| doc.add_element('root').tap do |root| write_text = 'bar' puts "Write Text: #{write_text.inspect}" root.add_element('foo').text = write_text end doc.write output: xml_string, indent: 4 end REXML::Document.new(xml_string).tap do |doc| read_text = doc.elements['/root/foo'].first puts "Read Text: #{read_text.inspect}" end puts "XML String:" puts xml_string Write Text: "bar" Read Text: "\n bar\n " XML String: <root> <foo> bar </foo> </root>

If you don't want to add extra spaces with indent, use transitive: true option:
require 'rexml/document' xml_string = '' REXML::Document.new(xml_string).tap do |doc| doc.add_element('root').tap do |root| write_text = 'bar' puts "Write Text: #{write_text.inspect}" root.add_element('foo').text = write_text end doc.write output: xml_string, indent: 4, transitive: true end REXML::Document.new(xml_string).tap do |doc| read_text = doc.elements['/root/foo'].first puts "Read Text: #{read_text.inspect}" end puts "XML String:" puts xml_string Output:
Write Text: "bar" Read Text: "bar" XML String: <root ><foo >bar</foo ></root > Actions
