Does REXML add spaces to comments?

Rubistas:

I'm using REXML to read and write XML too often.

Whenever REXML saves a comment, it adds linefeeds to it. Because I
write too often, these are stacking up. Is this my fault? I tried
various doc.write(f, x) options for the indentation levels.

Ruby 1.8.2 (from the Pragmatic Programmers' way cool installer).

Doesn't seem that way for me:


#--------
require 'rexml/document'
doc = REXML::Document.new( "<foo>Text</foo>" )
doc.root << REXML::Comment.new( 'My Comment')
puts doc # <foo>Text<!--My Comment--></foo>
#--------


This is using

ruby 1.8.2 (2004-11-06) [i386-mswin32]

on Win2K

I believe this is Curt Hibbs' work, now referred to as the "One-click
Installer."

I cannot reproduce the problem using a 4 line program like that, with a copy
of the production XML that causes the problem. Thanks for trying. I have to
look closer at the production then...

I have the same problem: Read document and write it
out again with (usually) doc.write(file, 0).
This adds some (at least one) linefeeds to previously existing ones.

Ruby version: ruby 1.8.2 (2004-11-06) [i686-linux]
