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 ��Caaaaa !"$"$��Caa��� \"��a ���}!1AQaa"q2���#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.
