String comparison

[leandronunes]

I was working in a project using web service on rails. I had a problem with a client of this web service because It was getting the a wrong result add the application crashes.

Searching the problem I found a bug in REXML on file:

/usr/lib/ruby/1.8/rexml/encoding.rb

On line 31 with the content bellow.

raise ArgumentError?, "Bad encoding name #@encoding" unless @encoding =~ /^[\w-]+$/

My app always raise the error but when I look into the encoding variable I saw the string. "\"UTF-8\"", so the string never match with the regular expression /^[\w-]+$/

I suggest replace this line with the code:

raise ArgumentError?, "Bad encoding name #@encoding" unless @encoding.gsub('"',) =~ /^[\w-]+$/

A test case would be appreciated.

Are you saying that, in your XML document, your encoding is something like this:

<?xml version='1.0' encoding='"UTF-8"'?>

Can you provide a small sample of your document that causes this error?
