[ruby-core:85802] [Ruby trunk Bug#10864][Rejected] REXML adds white space to text property when indent > -1

Issue #10864 has been updated by kou (Kouhei Sutou).

Status changed from Assigned to Rejected

If you don't want to add extra spaces with indent, use `transitive: true` option:

```ruby
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:

```text
Write Text: "bar"
Read Text:  "bar"
XML String:
<root
><foo
    >bar</foo
    ></root
>
```

Bug #10864: REXML adds white space to text property when indent > -1
https://bugs.ruby-lang.org/issues/10864#change-70655

* Author: amclain (Alex McLain)
* Status: Rejected
* Priority: Normal
* Assignee: kou (Kouhei Sutou)
* Target version: 
* ruby -v: ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
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.

~~~ruby
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
~~~

~~~text
Write Text: "bar"
Read Text:  "\n        bar\n    "
XML String:
<root>
    <foo>
        bar
    </foo>
</root>
~~~
