Subject: remove newline characters in d anchors

hi

i am working on this code where i need to list the files in a dir and
store it in a xml, which i managed to do. however in the generated xml
there are newline characters (\n) appearing before and after the actual
text value of each node.

below is the code i am using

require 'rexml/document'
require 'find'

doc = REXML::Document.new
main = doc.add_element 'main'

main.attributes['name'] = ""

# Find.find('./'){|path| puts path[2,path.length] }
Find.find('./'){|path|
  if path != './dirlisting.rb'
    if ! File::directory? ( path )
      newfile = main.add_element 'file'
      newfile.text = path[2,path.length]
  end
  end
}

outfile = open('dirlist.xml', 'w')
doc.write(outfile, 0)

# open('dirlist.xml', 'w') { |f| f << doc}



below is the sample output in the xml wid newline characters before &
after each text value within the anchors
<main name=''>
<file>

</file>
<file>
</main>

how can i get rid of those line breaks in each nodes and have a clean
node with just the text value?
