Rails - Jul 2009 - Problem when copying files somehow related to REXML

Hi guys.
I am trying to copy files from one folder to  another.
The code is quite simple:

      frompath = File.join(fromdirectory,filename)
      topath = File.join(todirectory,filename)
      FileUtils.cp(frompath, topath)

The code actually works and indeed copies the images.
The problem is that right after copying them, the REXML throws the
following exception:

REXML::ParseException
 log:
#<RuntimeError: Illegal character '&' in raw string
"���� JFIF    ��;CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality 85
��C                      
                   !         "$" $    ��C                             
��   �
\  "      ��                 
 ���             }       !1A  Qa "q 2��� #B�� R��$3br�
     %&'()
*456789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz���������������������������������������������������
..

So., what does REXML have to do with the code?
The actual filename comes from a parsed element. The code previous to
the copy does something like t his.

 doc = REXML::Document.new(screencontent)
    doc.root.each_recursive {|c|
      if c.name == 'File'
        images << c.attributes['source']

After that, I loop through the images array to get and copy all of the
image files.
I must insist that before throwing the exception, the files are
actually copied.

Thanks so much for your help in advance.

Could you show the entire code - it''s hard to say much from the
fragments you''ve posted.

We had faced same type of problem while working on www.scrumpad.com ,
next generation scrum project management tool. In that case we have
installed a gem rexml fix. that had saved us from this problem you
can check that one.

basically rexml is used for parsing

I found the error. It was actually my mistake. Later in the code for
whatever reason I was actually opening and trying to parse an image
file with REXML, so it was breaking there, not in the previous part.

Thank you so much for your useful replys.
