Preserving EOL styles during SXML (de)serializing with xml->sxml/sxml->xml

Hi Guile community!

First of all, thank you for the wonderful language you created.  It's
super fun for me to try to get stuff done using Guile.

Now to my problem: I have an XML file like this:


[-- Attachment #2: eol-guile.xml --]
[-- Type: application/octet-stream, Size: 139 bytes --]

<root>
  <node>Text with Windows
  line endings, that is, CRLF.</node>
  <node>Text with UNIX
  line endings, that is, LF.</node>
</root>

In this file there are elements that contain text nodes with CRLF
(Windows style EOL) and ones containing LF (UNIX style EOL).  I wish to
preserve the CRLF line endings.  However, the following little script
shows that they get lost during reading/parsing:


[-- Attachment #4: eol-guile.scm --]
[-- Type: text/plain, Size: 214 bytes --]

(use-modules (sxml simple)
             (srfi srfi-26))

(let ((sxml (call-with-input-file "eol-guile.xml" xml->sxml)))
  (write sxml)
  (call-with-output-file "eol-guile-written.xml"
    (cut sxml->xml sxml <>)))

[-- Attachment #5: Type: text/plain, Size: 170 bytes --]


After reading in the file and parsing it to SXML the CRLF is gone.  This
seems to happen during the SXML parsing.  How do I prevent this from
happening?

Thanks,
Daniel
