Problem when copying files somehow related to REXML

Rails
1

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.
