Hi Robert,


As for the code that I am using, I simplified the code in my original 
post. The first line:

doc = REXML::Document.new error

Should parse in the XML document and recognize all of the roots, 
elements, attributes, etc. from the input document.

i.e.:
puts doc.root.attributes["test"]

Should return "yes" because the attribute in the error xml file (see 
above) is "yes. With the extra line, it puts "nil". (because the parser 
did not do its job).

I tried converting all of the files to UTF-8 and they still did not 
work. (If you remove the extra line, it does work) I do not think the 
problem with is in the unicode.

Thanks,

Mike
